= PPU insulation foam with foam, Dnepropetrovsk region UAH

quality insulation-one of the main conditions for the creation of a comfortable microclimate, reduction of heat. The construction market offers dozens of varieties of materials - from traditional mineral wool to innovative polyurethane foam.
= Polyurethane foam is two main types - finished products (plates, pipe shells) or a two -component spacing mixture. It is the sprayed material now that is of increased interest among experts and consumers.
What is PPU
Polyurethane foam can be compared to foam.
Polymer has the ability to increase in volume immediately after application.
It may contain open and closed cells.
The second type contains an impermeable film on the surface.
It can be applied to the roof structure on both sides. Open cell heater promotes free penetration of air.

Different types of PPU differ in structure. The foam can be soft, rigid, semi -rigid. The denser thermal insulation, the higher its efficiency, higher cost.
The choice of specific composition always individual. It all depends on the customer's budget, the characteristics of the roof pie, the purpose of the structure, climate of the region.

Останнім часом утеплення нанесенням ППУ стало більш затребуваним завдяки оптимізації вартості.
Concerning the benefits of materials and technology, then these include:
high tightness caused by the absence of seams, joints, etc. ;|| 172
тривалий термін служби;
Very low weight;
compatibility with a variety of materials;
powerful adhesion with surfaces;
ecological safety;
Effective thermal insulation and noise insulation;
fire and biological safety;
high application rate.
There are no obvious operational shortcomings in the material, provided that quality raw materials and proper application are selected. Special equipment for mixing and feeding foam has a high cost. It is absolutely meaningless to buy for one -time work.
Choosing a PPU insulation, consult professionals. It is more profitable to order complex services, the isolation of several elements, for example, roofs and walls. || 127
