One of the types of foam is considered to be a material such as gas-filled polystyrene foam (PPS), made, respectively, using industrial technology of foaming and mixing with each other:
- Polystyrene itself.
- Styrene copolymers.
- Derivatives and binders.
Styrene granules in special chambers are filled with gas (natural gas to obtain a common material or carbon dioxide for the manufacture of fire-fighting brands) and take the form of the form in which they are filled. As a rule, these are plates of the required dimensional parameters. In construction, for insulation of internal and external walls, floors, as well as roofs, 2 main types of PPP are used (detailed information on sizes is presented here on the supplier's website).
Extruded PPP
An excellent material for carrying out internal insulation of any premises and surfaces. Despite the fact that it has a pronounced porous, microscopic structure, it has:
- Absolutely low vapor permeability and thermal conductivity.
- Great operational resource.
Insulation is available in various sizes of slabs. For ease of installation and increased tightness, it has grooves along the entire perimeter equal to half the thickness of the material. Laying is carried out in "overlap", the groove of one on the groove of the other plate.
Foamed PPS
Affordable and lightweight material, which is 98% air in the granules filled with it. Plates are available in various thicknesses (it is selected after appropriate calculations), they are usually used for external insulation.
The installation technology of both types of PPP is selected depending on the specifics and features of the work. For example, external plates are fixed using special dowels, while internal ones are often fixed only with glue.
You can choose the type and size of insulating boards with the help of the website of the NOVOSTROY company, which supplies them directly from manufacturers. All product names presented on the pages of the catalog correspond to the declared technical parameters for thermal conductivity and have a quality guarantee.
