Penoplex is a type of foam with an improved set of characteristics. For its manufacture, polystyrene is taken as a basis, an improved type of foam with expanded polystyrene in the base.
This material is well suited for thermal insulation of houses, interior and exterior wall decoration. And to fix it, use a special glue for penoplex.
Glue for installation of insulation penoplex is used for outdoor work, for indoor work, has different classes of frost resistance and consumption per 1 ²m.
It is produced in various versions: glue, foam, mastic, dry substances that require dilution with water.
There are bituminous and acrylic adhesives for installing foam. Each has its own advantages and disadvantages.
Let's try to take a closer look at each of the types, and also tell you about the unique qualities of foam as a material for insulating walls, roofs and foundations of houses.
On the building materials market there are various types of this material that are created for specific purposes. For insulation of the base there is a special marking of the product "Foundation". Its technical features are aimed at resisting pressure, it is able to withstand the weight of compacted soil.
If you follow the rules for fixing the foam, you can create excellent conditions for waterproofing. For reliability, a special water-repellent film can be placed under the layer of material.
Penoplex for walls is the most demanded type of material.
It is produced in the form of sheets up to 10 cm thick, its resistance to compression is lower than that of the previous type, but it was also created specifically for wall decoration.
For roof work, there is a product labeled "Roof". Such insulation needs an individual approach. The process of applying glue for fixing the foam must be accompanied by special scrupulousness, with poor vapor permeability, excess moisture will accumulate in the attic.
Penoplex almost does not absorb moisture, so it does not lose its original properties. The material is able to withstand many periods of freezing and defrosting. The styling of the foam is easy due to its low weight. Dry components make up 2% of the total weight, the rest belongs to different gases.
This material is a kind of pillow that retains heat well. Penoplex does not lend itself to the formation of rot, even in the case of contact with the ground.
This is a good property when it comes to insulation of heaters and refrigerators, and for houses, completely unsuitable quality. After all, condensation will accumulate inside the room.In order to avoid unpleasant problems, it is necessary to make forced ventilation in the building.
Even treatment with fire retardants will not help in case of a fire, penoplex releases carbon monoxide into the air.
For material installation use:
Each separately taken product has separate instructions for use, as well as the permissible threshold for use at different temperatures.
These compositions are characterized by the fact that they need to be diluted with water in certain proportions.
Dry glue for gluing penoplex consists of alabaster or cement.
It is believed that such substances are most suitable for indoor work. It is permissible to use dry glue for outdoor work when the outside air temperature is not lower than zero.
The advantage of a dry formulation is that it has a long shelf life at low indoor humidity. The setting time of the glue is within the normal range of about 4 hours.
To prepare the mixture, it is best to use a construction mixer that will stir the mixture without lumps. Before applying glue for foam insulation, the surface must be cleaned and coated with a primer for reliable adhesion of materials. Ceresit CT83 and Atlas Stopter K-20 are considered good examples to use.
Glue Ceresit for CT 83 foam is compatible with any surfaces, has a high level of frost resistance. Atlas Stopter K-20 has a consumption of 4.
4 kg for 1 m² of foam, it contains reinforcing fibers. Available in 5 - 25 kg bags. Pay attention to the level of frost resistance. F50 is suitable for interior work, F100 for external work.
When choosing an adhesive for frost-resistant foam for outdoor use, pay attention to the protection class, the coefficient of which should be at the level of F100.
This type of glue for penoplex cannot boast of a long shelf life. It is available in pressurized cans with an application gun. For those who will use it for the first time, fast solidification will seem more a disadvantage than an advantage.
There are only 30 seconds to fix bugs. glue Penoplex , which contains polyurethane, can be considered a good option for use.
Also, Insta-Stic is a quality adhesive with a capacity of 750 ml, which is enough for an area up to 15 m 2 . Penoplex glue Tytan Styro-753 is used for fixing insulation on metal bases.
Penoplex foam-glue Fastfix 750 ml is often used to fix material to various surfaces: tiles ceramic, concrete, aerated concrete, drywall, brick, wood, stone, metal.
Glue foam for penoplex is available in 750 ml cylinders, has a bluish tint. Not suitable for foil materials, Teflon, silicone, polyethylene.
Drying period 10 - 12 minutes, final hardness comes in 30 - 40 minutes. Suitable for external and internal work.
It is not advisable to use polyurethane foam to fix the foam, since it has a large expansion ratio, which will entail surface deformation.
Bitumen glue for penoplex in the form of mastic is used in cases where good protection against moisture penetration is needed.
We advise you to carefully read the composition of this product, as it often contains a solvent that will corrode the material.
The best option for use is Bitumast mastic XPS , which is made from petroleum products, but does not contain a solvent. Before starting work on fastening the foam, the mastic must be heated to a temperature of 90 ° C. The advantage of this mastic is that it is consumed minimally - 1 l / 1 m².
Acrylic foam adhesive is used to attach to wood, concrete, brick surfaces.
It is used for interior and exterior wall decoration with insulation, attractive for its economical consumption. Bitumen-based mastics have the best moisture resistance properties and are resistant to subzero temperatures.
In order to fix the penoplex easily and without any particular difficulties, you need to prepare the surface first. Clean it from dirt, dust, debris and dry it. Cover the substrate with a primer if necessary.
Then cut the penoplex into pieces of the required size using a jigsaw or a clerical knife.
Before starting work, make a gluing plan. Mineral wool can be placed under the penoplex if there is a need. There are such methods of gluing the material:
Most often, they use a point method, in which the glue is spread over the surface with a wide spatula, wait a certain time and press the penoplex against the wall.
Then, the joints must be coated with the same glue or mounting foam.
After the foam glue is completely dry, the foam can be reinforced with dowels for strength. Now you can start finishing work. Putty is applied in thin layers slowly. After the first layer, a reinforcing mesh made of plastic or metal is attached.
The thickness of the first layer should be no more than 1 cm, the second slightly less. The third layer is applied by spraying with a thickness of about 5 cm.for external protection of penoplex, means with high adhesion are used Master, Ceresit, Polimin, Giprok.
