polyurethane foam insulation – Polyurethane foam – a popular insulation material that can be used for insulation around the house . Polyurethane foam has a huge number of benefits and can be applied to the surface of any complexity. Polyurethane foam insulation will provide the best-quality heat , steam and waterproofing with any room , inside or outside .
Polyurethane foam was discovered in 1937 by German scientists led by Otto Bayer . At first, this expandable material was used in the aviation and defense industries , and in the 1970 began to be used for thermal insulation of residential buildings. There are soft and rigid polyurethane foams are used in almost all spheres of human life . As the insulating material used only with rigid polyurethane closed cell structure , since they have low thermal conductivity , excellent water vapor permeability and waterproofing characteristics .
Rigid polyurethane foams are applied in two ways: spraying or pouring . Spray polyurethane foam can be made directly on the outside wall material for finishing inside the building or on the wall under the sewing the . Fill foam produced in the spaces between the main wall material and has the same effect as spraying . This insulation material has proven itself as the best insulation not only for any residential or industrial premises, but also as insulation for basements , foundations and basements . For example , a layer of spray foam thickness of only 3 cm gives a much greater effect of warming than the mineral wool layer 20 cm thick.
Polyurethane foam insulation , though superior to the traditional ways of warming costs , but pays for such expenses in full. The fact is that if any other type of insulation thermal insulation materials can not be avoided joints and gaps. Polyurethane foam is applied evenly on anyone, even the deformed surface , has no seams and fill all joints and voids . This eliminates the so-called “cold bridges” in interpanel seams.
If applying foam spraying occurs , the material hardens in less than a minute after application . Also excellent thermal, acoustic and waterproofing properties , this material is resistant to organic solvents , alkalis and acids , is not affected by microorganisms and can withstand thermal stress from -180 ° C to +120 ° C.
Spray Polyurethane Foam Insulation
As already mentioned, the polyurethane foam can insulate any part of the house . For example, for the polyurethane foam roof insulation can be applied from the outside to the main roofing material (metal , slabs , slate , etc.) followed by staining for protection against the effects of UV and inside on the roofing material and load-bearing structures . Polyurethane foam for insulating walls can be used at the time of construction or finished walls under the facing material ( drywall, siding , paneling , etc.). If applied polyurethane foam on the walls , then simply clean the surface of any building materials and dry it.
Polyurethane foam insulation by spraying their hands theoretically possible if you have a special setting and experience of such works . There are specific sets of such equipment , complete with whom he goes and polyurethane foam . The only disadvantage of such equipment for home use is a restriction on the area of application and the possibility to use the device once only. If you need to carry out large areas of insulation , it is better to refer to specialists .
