How to glue polyethylene foam together

There are a large number of insulation options on the market. Foamed polyethylene is the most commonly chosen material because it has impressive vapor, heat and sound insulation properties. The choice in today's market is truly great. The proposed options may have a self-adhesive surface, may be foil-coated on one side or both. There are such types of foamed polyethylene on sale as isolon, polyfom, penofol. The insulation can be attached to different materials. And depending on all its characteristics, glue is selected.

The main advantages of foamed polyethylene

Despite the availability of thermal insulation materials on sale, the production of which began later than foamed polyethylene, insulation materials of the Isolon, Temaflex, Polyfom, and Penofol brands are in consumer demand because:

the material has low thermal conductivity;
the air-bubble structure of the insulating material prevents the spread of water vapor and the penetration of precipitation;
the small thickness and high flexibility of the material facilitates installation, and the adhesive for polyethylene foam ensures its reliable fixation on the surface of building structures;
if foamed self-adhesive polyethylene is used, installation of the heat-insulating layer is greatly simplified; it is carried out at the joint, over which aluminum tape is glued;
if foil-foamed self-adhesive polyethylene is used, then after insulating the surface of the building structure with Penofol, it even acquires a certain beauty.

Best answers

Try to stick it with drool...

You'd be better off insulating it with polystyrene foam from the outside. and the floor can be insulated. You talk to those who do this.

I think you need to consult a construction store at the store or try installation

First, prime it several times with bentonite, and then glue, but it’s better with a heat-insulating layer, even PVA, but there are some that are sold as self-adhesive on a heat-insulating backing.

think about it, maybe galvanized iron, or better yet stainless steel, because foil is weak

oh, if the sticker is crooked, get a magnifying glass, with a focus like in ancient Greece they burned the fleet)

I use Termoizol - foil on foam, it’s easy to work with: I insulate steel baths - they turn out no worse than cast iron ones, they are warm. And food grade can be glued onto cardboard with slots for hooks for easy insertion.

Buy penofol, they are sold in different thicknesses. It can be self-adhesive, but if not, try double-sided tape!

If the foil is glued to the glass with egg yolk, then it will definitely stick to the concrete

Adhesive mixtures for polyethylene foam

Experts, when recommending how to glue foamed polyethylene, suggest two-component mixtures based on methyl acrylate. For example, the well-known mixture from “Easy-Mix PE-PP”, which demonstrates high adhesion, allowing you to work even with polypropylene and simple polyethylene.

They have proven themselves well:

“Quick-Bond” or “88-NP” (universal adhesive for this material;
Akrol contact;
spray "Neoprene 2136".

If you need to glue foamed polyethylene together, you can use:

Cerezit CT83;
Anserglob BCX 39;
polymer cement mixture called “Aqualit SK-106 P”;
"Master Super";
"Polymin P-20";
polyurethane aerosols “Stolit PC” or “Tytan Styro 753 O₂”.

The wall must be pre-cleaned, treated with an antiseptic, dried, and, if necessary, leveled. When fixing insulating material over large areas, we recommend using the adhesive mixture “Facade” or “Bolars” (packaged in 25 kg), pre-preparing the working solution in accordance with the manufacturer’s instructions.

Foamed polyethylene is often used for insulation and waterproofing, but for an effective and high-quality result, special glue must be used in tandem with polyethylene.

There are several types of glue:

— for exterior finishing and insulation, mounting adhesive for exterior work or liquid nails, which have a high degree of strength and are resistant to temperature changes and adverse weather conditions, are suitable;

- in a room with a high degree of humidity, in a bathhouse or bathroom, you will need MV-40 glue, which does not lose its adhesive qualities in a damp environment and has water-repellent properties;

— when insulating the inside of houses, apartments and other residential premises, you should choose non-toxic glue labeled “universal” or “express”.

There are also professional adhesive-based mixtures that have high performance and perform their functions perfectly. When dry, this mixture acquires a similar structure to the material, which gives solidity to the bonded surfaces. The correct choice of adhesive composition will help make the insulation of the room not only effective, but also durable.

Some tips for working with the material

When carrying out gluing work, you must follow the advice of the masters:

If maximum joint strength is required, then only the welding method is used. In this case, the cooling of the weld should occur gradually.
Cleaning and degreasing are carried out using any connection method.
If acrylate glue was used, the connection should be kept at a temperature of 15–70 degrees for 5 hours.
Epoxy glue does not provide the desired connection and is more difficult to work with.
It's not difficult to make your own glue. To do this, crushed chalk or cement is added to acrylate glue.

Features of choosing adhesive for polypropylene and polyethylene

At home, vapor and waterproofing can be done with ordinary foamed polypropylene (polyethylene). Polypropylene insulation, although primitive, is highly effective, allowing you to save on the purchase of more expensive analogues.

Adhesive mixture for polyethylene

But you can’t get by with polyethylene alone, since its use requires polyethylene glue. In rarer cases, other adhesive-based mixtures are also suitable. They are needed for fixing polyethylene (the so-called polyethylene gluing) on the surface of thermal insulation or any other building structure.

And among the many different adhesive-based mixtures, it is necessary to choose the most optimal and effective one.

In order to glue polyethylene to thermal insulation, experts recommend using a specialized adhesive-based mixture “Easy-Mix PE-PP”.

Baths

Energofol insulation materials, which have a protective layer of aluminum foil, are placed under the internal lining of the room (with the foil inward). These materials are designed to resist heat without releasing any odors or harmful gases.

Energofol materials are also used for thermal and sound insulation of refrigerated containers and isothermal bodies, for air conditioning systems (as an insulator for air ducts) and pipeline systems. In residential premises they are laid between the wall and the heating radiator.

The materials are ideal for insulating roofs and attics. Mounting to the roof is identical to mounting to the walls. The material is attached to the rafters from below, with an aluminum layer inside the room. When using materials with double-sided coating, an ideal microclimate will be maintained in the house at any time of the year.

The use of Energofol coating in a “warm floor” heating system leads to:

reducing energy costs;
reducing floor heating time;
reducing the heating of the ceiling of the apartment located on the floor below.

Maskizol
Overlap
A heating element
Cement-sand screed
Ceramic tiles, linoleum, carpet

To increase the efficiency of the “warm floors” system, materials with a thickness of 3 mm, 5 mm, 10 mm are used. The material is placed under the heater with the reflective surface facing the room. The Energofol material reduces heat loss spent on heating the underground space and evens out the temperature field of the apartment.

When insulating the floor using electric heaters, you must carefully comply with electrical safety requirements, since aluminum foil is an excellent conductor of current.

In addition, Energofol is perfect for installing a “floating floor” (when the thickness does not exceed 3 mm), when installing heated floors located above a cold space, as well as when insulating the floor “along guide joists” (the material is laid between the joists).

What glue to use for gluing polyethylene - composition

The easiest way is to purchase structural adhesive in the store, which contains methyl acrylate. Its properties ensure rapid softening of polyethylene and its further gluing. The glue also contains inorganic and organic acids and xylene, chromic anhydride and various additives.

The advantage of using the mixture is that no additional processing of the material is required. However, polyethylene glue is quite toxic, so it is recommended to carry out work outdoors. The glue acquires its best properties at a temperature of +35C; it is not afraid of moisture, but is flammable. It is better to buy it in specialized stores so as not to run into a fake.

If there is a need to combine polyethylene with polyethylene, it is more convenient and easier to resort to heat treatment.

This technique allows you to obtain a strong, unbreakable seam. Among the disadvantages of the method, it is worth noting the deformation of the edges of the product.

Mixtures for combining polymers are available for sale, with a consistency similar to a thick paste. An activator is included in the kit. After adding it to polyethylene glue, it acquires the necessary consistency and can be used for the near future.

Gluing polyethylene - step-by-step instructions

To glue polyethylene, you do not need special knowledge and skills. Even beginners can cope with the task at home.

The operating procedure is as follows:

Clean the surface and degrease it. Some manufacturers claim that this step is not mandatory, but experts still recommend spending a few minutes and under no circumstances skipping it.
Apply glue to the treated material. It will only take a few minutes for it to harden, so the parts need to be attached to each other without delay.
Leave the glued polyethylene elements for several hours until the glue completely sets.

In general, this algorithm is similar to working with any glue. However, you should take care to use protective gloves, since the glue can cause allergic reactions and is quite toxic.

It is more convenient to apply the adhesive using a glue gun, which can be loaded with ready-made cartridges. The mixture of them is distributed evenly, so it is easy to achieve the desired dosage. If you are planning a large amount of work, this device is worth investing in.

How to glue foamed polyethylene

Foamed polyethylene has a porous structure, therefore it provides high-quality heat, steam and waterproofing.

Types of isolon

This material is polyethylene foam, sold in the form of rolled sheets, sleeves or rolls.

The thickness of this material varies from 1 to 50 mm. There are two types of isolon: physically cross-linked, closed-cell (PPE) and non-cross-linked, gas-filled (NPE).

PPE isolon, the characteristics of which are in many ways superior to those of other insulation materials, should be supplemented with the following characteristics:

low specific gravity (which is important for the upper tiers of light frame structures) - from 30 to 200 kg/m³; good sound insulation properties (up to 68% sound absorption); ability to reflect thermal energy – up to 97%; softness and elasticity (allow you to fill hard-to-reach areas); durability (isolon is not afraid of insects and does not rot) - service life exceeds 90 years; environmental safety (non-toxic, does not emit odor, does not irritate the skin, chemically neutral); wide temperature range of application (from -60 to +75°C); versatility of use (used in residential, industrial premises, garages, warehouses, etc.); availability of the material (you can buy isolon at any hardware store); simplicity and ease of installation.

Izolon (sample photo attached below) NPE is different:

lower density (within 19 – 35 kg/m³);
thickness (up to 16 mm);
sound absorption does not exceed 13%;
thermal conductivity – at the level of 0.040 W/μ;
vapor permeability – about 0.001 0.001 mg/m×h×Pa;
water absorption – 0.2%;
temperature range of use – from -80 to +80°С.

What kind of glue to glue foamed polyethylene with?

When choosing insulation, a special place is occupied by foamed polyethylene - a material with sound, heat and vapor barrier properties. Depending on the manufacturer, it can be penofol, isolon or polyfoam. The construction market offers different types: with one-sided or double-sided foil, as well as with a self-adhesive plane. The material on which the insulation is attached also varies. Based on all the parameters, you need to be able to choose the appropriate adhesive for polyethylene foam.

How can parts made from these materials be glued together?

There are two types of adhesive materials:

single-component ones are sold ready-made (for example, “Moment” adhesive-sealant);
two-component ones are a kit consisting of a base and a hardener, which must be mixed before work (for example, epoxy glue with a hardener or “Plasticfix”).

All adhesive compositions can be divided into three groups:

cold cure (harden at room temperature);
thermosetting (heating is required for their polymerization);
mixed (polymerizes with and without heating).

Adhesive mixtures contain substances that dissolve the polymer and improve adhesion of the additive. The volatile solvent evaporates quickly, causing hardening at the joint. The parts form a single whole, which is why this process is often called cold welding.

Features of penofol fastening

Penofol (isolon) is produced by special foaming of polyethylene. The insulation is covered with aluminum foil, which maximizes heat retention. It is used for internal and external work, in finishing production mechanisms, preserving heat in pipelines or air conditioning systems. It comes in rolls and individual plates. It may have additional characteristics – thickness, color. The bonding of foil to the plane of foamed polyethylene can be chemical or physical (cross-linked).

small thickness;
environmentally friendly;
does not require additional skin and respiratory protection;
there is no need for special tools;
ease of fastening.

Glue is used for penofol with foil on one side.

Double-sided insulation is used for thermal insulation of loggias, garages, and pipes. They are attached to the sheathing or purchased polyethylene foam with a self-adhesive surface.

Due to the lightness of the insulation material, the load-bearing capacity of the adhesive is not so important.

Foil insulation for walls and floors

Foil insulation has relatively recently appeared on the construction market, but is rapidly gaining popularity for various reasons. Next, we will consider the types of this material, the advantages in comparison with traditional insulation and how to use it correctly.

What is rolled foil insulation

This is a combined material for insulating walls, floors and ceilings, consisting of several layers:

The material is rolled, therefore it has a relatively small sheet thickness. How does heat retention occur?

Varieties

Roll insulation materials are classified according to the main material:

Each of the presented materials is intended for use in certain conditions.

Application

Penefol (closed cell polyethylene foam) is versatile in use. They insulate walls and floors in residential premises.

Foil insulation for pipes and roofing - foil insulation. It is also used in the construction of industrial facilities.

Rolls of mineral wool with an aluminum layer are used in the same way as conventional insulating mats: for insulating walls, floors and other structures. The difference between foil-coated mineral wool and regular wool is the built-in waterproofing; aluminum does not allow moisture to pass into the fibers, preventing the material from getting wet.

The ideal insulation foil for a bathhouse is based on basalt: it has a low heat transfer coefficient, is not afraid of humidity and large temperature changes. As you know, stone wool is a hard material. To roll it into a roll, the basalt is sawed into lamellas, which are laid on an aluminum base. This insulation is used to insulate various social and industrial facilities.

Foiled polystyrene foam is used for floor insulation.

All materials with a layer of aluminum foil have higher technical performance than their traditional form. The cost of foil insulation is an order of magnitude higher than the cost of conventional material; this is the main disadvantage of the “advanced” sample.

The first and most important question is which side to put the foil insulation on?

The first rule of installation: the reflective side should be directed towards the room. This will ensure natural heat reflection.

The structure of insulation and finishing must be thought out: in the case of walls, there must be an air gap between the insulation and subsequent finishing. When using a mineral wool base, it is necessary to insulate the material from the penetration of water; for this, a membrane is attached to the base, allowing steam to pass out.

How to attach foil insulation to a wall: roll out the insulator over the fixed membrane and fix it with guide rails, the thickness of which should exceed the thickness of the main insulation. The layers are connected with staples along the edges of the slats. Subsequent finishing of panels or lining is carried out along guides, which provide an air gap with their thickness.

Some craftsmen recommend protecting the foil with vapor-proof films to prevent moisture from entering the body of the mineral wool layer through possible holes in the metal.

For wooden and concrete floors, the algorithm of actions remains identical:

If the room has an electric or water “warm” floor, the rolls are rolled out with the reflective side up, a reinforcing mesh is laid on top, then heating elements and a cement screed is produced followed by cladding.

Foil insulation for walls and floors

Let's look at the types of foil insulation, its advantages over traditional insulation, and how to use it correctly.

Glue selection

The range of adhesives for penofol on the modern market is quite wide. Therefore, it is important to take into account the different characteristics of materials.

General rules

Penofol adhesive is selected based on the following:

the product has durable adhesive properties;
the thermal range coincides with the temperature characteristics of the insulation;
a non-toxic certified product is used in the interior decoration of residential premises (apartment, office);
for external finishing, you need glue that is resistant to temperature changes and weather conditions;
saunas and baths require mixtures with water-repellent properties;

Watch the video to understand better:

Water-based glue is not suitable for gluing isolon!

A water base will not create the required level of penetration into all the pores of foil polyethylene foam. The grip on the surface will be insufficient.

Types of glue

Choose what to glue with, also evaluating the surface:

Weicon Easy-Mix PE-PP 45. Bonds polypropylene and polyethylene. It hardens for a long time;
Titanium. Optimal for concrete base;
Atlas Stopter K-20 glue. Adheres to mineral substrates;
T-Avangard-K is used at high humidity;
Contact Acrol or Neoprene-2136 spray is glued to penoplex;
Ceresit and Olfix are universal - they are attached to any surface, including concrete;

The seams are treated with Tilite or special tape.

Review of popular solutions

To fix foam plastic, universal means, one-component substances, mineral mixtures, and polymer glues are used, the list of which is constantly growing.

Weicon Easy-Mix-PE-PP 45

The product, which contains methyl methacrylate, is produced in the form of a yellowish paste that becomes transparent after hardening. The two-component adhesive has high adhesion, can withstand -50, hardens completely in 6 hours, and is used for joining:

fiberglass;
polycarbonate:
polyvinyl chloride.

Before applying the composition, the surface does not require preliminary preparation. The peel strength of the adhesive is 2.9 N/mm.

"Titanium"

Titan Wild has been used in construction and renovation work to connect different surfaces since the 90s. Cyanoacrylate glue is applied in a layer less than 4 mm thick; the composition is effective even at very high temperatures. The hardened seam does not delaminate under heavy load. The consistency of the product resembles polyurethane foam, but does not shrink. The glue dries in 60 minutes and is applied in 2 layers. After drying, the seam is not destroyed by ultraviolet rays and does not absorb moisture.

Atlas Stopter K-20

The mineral mixture is used for gluing insulating polystyrene foam boards when insulating buildings, as well as for creating a reinforcing layer. Microscopic fibers present in the glue give it resistance to cracking, high adhesion, and elasticity. The building mixture connects the panels to plastered walls, brick, and aerated concrete.

"T-vanguard"

The adhesive, consisting of a polymer and filler, is available in the form of a dry mixture, suitable for attaching polystyrene boards to the facade of a building and indoors. "T-avant-garde" is packaged in paper bags of 25 kg, applied:

on concrete;
brick;
plaster.

The surface to which the panels are attached is degreased and leveled in advance. The mixture is combined with cold water and consumed in half an hour.

"Akrol"

The adhesive, which contains additives that increase adhesion, ensures a strong connection of the insulating board to glass, metals, and concrete, even at high temperatures and humidity. Akrol glue seals small cracks, masks unevenness, is applied to a dry surface in a continuous layer, and pressed against the base. The glue does not need to be diluted, since it is packaged into parts and ready for use.

"Neoprene-2136"

In order for foamed polyethylene to perform the functions of insulation and insulating material, it can be secured to a wall that has been cleaned and treated with an antiseptic solution using Neoprene-2136 spray. The adhesive is made on the basis of rubber, contains additives and fillers in the form of silicon dioxide and calcium silicate, and provides adhesion in a quarter of an hour. The compound is resistant to the action of acetone, alcohol, and aliphatic hydrocarbons.

"Ceresit"

Construction adhesive with high adhesion allows you to attach polystyrene boards and ceramics even to surfaces subject to shrinkage.

The product, produced by Henkel, fills the seams and reliably adheres the insulating material to the surface.

Several types of Ceresit glue are used for connecting slabs inside and outside a building, which is valued for its characteristics, which differ in:

resistance to sub-zero temperatures;
water-repellent property;
high adhesion;
ease of care.

The Ceresit line contains cement, which upon contact with liquid enters into an alkaline reaction. When working with glue, you need to protect your skin so as not to cause irritation.

"Olfix"

The product produced by Knayf is suitable for gluing mineral wool and expanded polystyrene panels to plaster and brick walls with an uneven surface. The glue, made from gypsum and additives, is poured with cold water and applied in portions in the center and along the sheet. The glued board is pressed against the base and aligned in one plane.

Penoplex Fastfix

To fix extruded polystyrene foam panels, foam adhesive based on plastic polyurethane is used. Penoplex dries in 10 minutes, hardens in a day, is suitable for external work, internal thermal insulation, and provides adhesion to plaster, expanded clay concrete, building stone, and wood.

Insta-stick

The polyurethane-based product firmly secures foam foam boards to horizontal and vertical surfaces of brick, metal, and concrete. Insta-stick glue is economical in consumption, is not afraid of frost, and does not contain harmful substances. During commit:

Doesn't splash.
Does not leave any dirt.
Doesn't gather dust.

The supply of the composition is regulated by pressing the valve. The glue is applied in strips, and after foaming it hardens in an hour or two.

"Moment"

In everyday life, construction and repair, a Russian-German product has been used for many years, which is constantly being improved and replenished with new varieties. Moment glue firmly and quickly secures ceiling skirting boards, foam tiles, parquet, and polypropylene products. The two-component composition reliably fixes materials that are exposed to steam, water, and vibration.

BF-2

The viscous alcohol solution, which contains phenol-formaldehyde resins and vinyl acetate polymer, developed in the Soviet Union after the war, does not corrode, does not rot, and does not deform when heated. BF-2 glues metal, plastic, polystyrene foam, ceramics using the cold and hot method. The thickened composition is diluted with alcohol. When fixing in room conditions, the product is applied in 2 thin layers, in a drying cabinet - in one.

BF-4

Butyral-phenolic glue connects metal surfaces, textile fabrics, leather, glass, wood. The durable seam is not dissolved by gasoline and is not afraid of moisture. BF-4 ideally fastens products subject to bending and impact. With the hot method, the parts are glued together in 40 minutes. With the cold method, the composition is applied in 2 layers with an interval of half an hour.

How to attach penofol

Attach penofol with the foil side facing the inside of the room. A greater thermal insulation effect is created by an additional air layer 1-2 cm thick (using a backing - sheathing).

By watching the video you will learn more:

Glue of different compositions for polyethylene foam can be ready-made or requires preparation on site. You must carefully read the instructions for the selected mixture:

The glue is applied in an even layer, paying special attention to the edges. Before sticking, you need to wait up to 1 minute so that the composition has time to be slightly absorbed. This ensures better adhesive properties. Attach the treated penofol to the insulated surface. The plates are fastened joint to joint, but not overlapping;
setting time varies depending on the characteristics of the glue (at least 15 seconds);
smooth the surface of the polyethylene foam, removing folds. Tape the seams, you can use foil tape;
glued insulation in residential premises requires additional decorative finishing. The last layer of the structure (plasterboard or lining) is installed on the sheathing.

Preparatory work

First, you need to properly prepare the concrete for gluing, which will ensure a monolithic, uniform connection. They eliminate all defects, unevenness, cover up cracks, repair chips, and thoroughly clean the surface from dirt and dust. Cover the base with a primer and wait until it dries completely. All metal elements must be treated with an anti-corrosion compound.

Gluing stage

The glue is applied to the side without foil in a thin, even layer, spreading evenly over the entire surface. The edges are impregnated with glue as thoroughly as possible so that the penofol does not lag behind the concrete surface. The insulation must be held for 10-40 seconds so that the adhesive composition can set and fix the sheet to the surface more efficiently. Next, the sheet is pressed against the concrete, carefully smoothed, distributed evenly, additionally gluing the seams.

Choosing a suitable adhesive for gluing penofol to concrete is a very important task that must be approached seriously. It is advisable not to skimp on the composition, since the strength, reliability, and durability of the fixation will depend on its compliance with the requirements and operating conditions.

How to glue polyethylene foam: choosing glue

We insulate the home

Since it’s quite cold outside, it’s important to provide your home with heat. As practice shows, the use of additional heating sections is not effective enough. The best option for this case is wall insulation. To carry it out, different materials, technologies, etc. are used. All this allows you to make the room warm and cozy at any time of the year. Moreover, it is excellent for both apartments and private houses.

Wall insulation is carried out in several ways. It can be done both on the outside of the wall, that is, from the street, and on the inside. The second option is used quite often today. And this is not surprising. After all, it consists in using a special cover for wallpaper. It is attached to the wall with glue. As a result, the walls turn out beautiful and well-groomed, providing comfort and coziness in the room.

Mounting features

Izolon (penofol) is covered with aluminum foil, which allows for the best possible retention of heat. Its adhesion to the surface of the insulation can be chemical or physical, that is, cross-linked. Izolon may have additional characteristics such as thickness or color. If you are looking for win-win insulation for your home, then this option will be the best choice. It is also perfect for insulating elements of air conditioning systems, pipelines, and production mechanisms. Foamed polyethylene is used for both external and internal work. The material has quite significant advantages.

Among them are:

small thickness;
ease of installation;
environmental cleanliness.

Installation of insulation is possible without the use of special tools. Working with foamed polyethylene does not require additional protection of the respiratory tract and skin. The material is so light that the load-bearing capacity of the glue will not be critical.

The most popular type of insulation with foil for interior finishing is aluform

Bestizol or alufom is a bubble base consisting of aluminum foil (outer layer) and polyethylene (inner layer) on one side. The foil acts as a reflector of solar and heat rays. The polyethylene layer has a cellular structure and neutralizes sound waves and shocks. The advantage of this material is low thermal conductivity.

Bestizol can be used in both cold and hot weather. Due to its small thickness (1 cm), the material is used for hard-to-reach places:

for winding ventilation pipes;
air duct coverings;
insulation of pipelines and other outlet communications.

How to choose glue

There is a fairly wide range of different adhesives for sale for working with polyethylene foam. And it is advisable to make the choice using the following criteria.

The temperature range must match this characteristic of the insulation.
Adhesive properties must be extremely high.
If you plan to use glue for interior decoration, it must be certified and non-toxic.
If adhesive is selected for exterior finishing, it must be resistant to a variety of weather conditions and temperature changes.
If you intend to finish the sauna and bathhouse, then the glue will need to be mixed with water-repellent agents.

Water-based adhesive is absolutely not suitable for working with isolon, because it does not allow the adhesive to penetrate into all the pores of the insulation. Consequently, the level of adhesion will be insufficient.

Answers from experts

.Moment. Apply in thin strips and glue

double sided tape is good

Nothing but a stapler. It will fall off. Tested many times. And food won't work. Look for foil for baths and saunas, preferably on kraft paper, so you can glue it with glue. Do not stick clean foil.

and why? If for thermal insulation - foam is better, for sound insulation it is better than mineral wool

not glue, but pin. With slats, you put the isolon on it, lay the slats evenly on it, drill holes, and fasten it. And so every 50 cm. Well, or vice versa - first the slats have a “lattice” of insulation on them. Is it really so difficult to figure it out? Why is it necessary to “glue”? It is pointless to glue anything other than stone or concrete to concrete. Otvalitsa. Or it condenses and leaves.

Special opinion, by the way, is right - a lattice made of slats with mineral wool and covered with plasterboard or plywood on top. Much better.

There is also a self-adhesive one - prime the concrete with any interior primer, let it dry for 12-24 hours and stick it on - and if it is not foil-coated, then you need to buy a foil-coated one - if not, then glue for linoleum type 88 I don’t know what it’s called, but the effect is one thin layer on one and on the other surface and glue

You need to know the strength of the concrete slab. try turning to professionals who work with them slav-beton /index.php?id=2 I’m sure they will give you advice on how to do this, or they will do your work for you. Good luck to you

Types of glue

We list the currently most commonly used glue options.

For rooms with high humidity, MV-40 is suitable, which has moisture-resistant properties. You can also choose T-Avangard-K.
For residential premises, “Express” or “Universal” are usually used.
If we are talking about installing external building structures, then it is best to choose liquid nails or assembly adhesive. For example, Moment Montage would be suitable.

Titanium is good for reinforced concrete base.
Neoprene-2136 in the form of a spray or Acrol contact type are selected for gluing to penoplex.
Olfix and Ceresit are universal glue options. They are perfect for working with any type of surface, including concrete.

Atlas Stopter K-2 kley is selected if you plan to glue the insulation to a mineral base.
Weicon Easy Mix PE-PP-45 is selected for gluing polypropylene to polyethylene.

After the work, the seams will need to be treated using Tilit or adhesive tape specially designed for this.

The choice of adhesive is largely determined by the purpose of the room that you plan to insulate, whether you will attach it to wood, metal, concrete, etc. It can be difficult to choose on your own without much experience in construction and installation work. Therefore, it is always advisable to consult with specialists.

In the Remonstr store you will find a huge variety of glue options. If you find it difficult to choose, contact our consultants for help, who will promptly respond to your request, help with placing an order, and clarify all the important details regarding payment and delivery.

Life time

Since foil insulation appeared relatively recently, it is not yet possible to determine the exact expiration date. However, after conducting experiments, we can say that the material does not lose its properties for 200 years.

The service life of the installed insulation depends on the adhesive used. If the adhesive composition has passed its expiration date, then you can re-install it with the same heat insulator.

There are a lot of insulation materials on the construction market. The choice is so wide that the question arises, which is better. To answer, you need to compare the characteristics of the thermal insulation material and the scope of application - street, living room, garage or agricultural building.
