How Does SPF Work?
Spray polyurethane foam (SPF) adheres to the wall and creates a continuous insulation and air barrier on the surfaces and cavities to which it is applied, even on profiled surfaces. Spray polyurethane foam (SPF) insulates and acts as an air barrier. Both are key to ensuring comfort at home and reducing heating and cooling costs. There are no cutting elements or seams to stick or seal.
The difference to other spray foam products is that it is an air barrier that prevents cold air from entering the warm areas and thus prevents moisture problems. The spray foam acts as an air barrier, preventing the escape of air that allows fibrous substances. The spray foam fills every space in the frame and seals the house while insulating it.
Icynene spray foam insulation is a barrier and insulation material that seals walls, floors and ceiling recesses against air movement, including the space around sockets and lights, and where the walls come into contact with windows and doors. Icynene spray foam insulation can provide effective air barrier insulation to minimise air access through walls and ceilings and prevent drafts, cold spots and loss of energy. Icynene spray foam insulation products are installed only by fully trained and licensed Icynene® contract partners.
The initial investment in spray foam insulation is higher than for fleece or blown insulation. However, the advantages of spray foam are now far beyond any other insulation options. Spray foam insulation helps work the heating and air conditioning system more efficiently.
Spray foam insulation is considered an environmentally-friendly product due to some of its properties. Mainly due to the significant impact on reducing the need for fossil fuels through energy savings, but also because SPF is also environmentally-friendly because it does not contain ozone-depleting chemicals, it does not contain CFC, HCFC, asbestos, formaldehyde and glass fibres.
Insulation from polyurethane spray foam is not only recognised as thermal insulation but also meets the requirements of the vapour barrier and air barrier. In fact, this is one of the best tested and strongest insulation products in history.
Insulation made of polyurethane foam is two-component spray insulation, which was designed to achieve excellent thermal properties on virtually any surface (wood, wall, posts and beams). When the foam is sprayed onto the surface, it expands and forms a complete, unbroken seal on the inner surface of the outer walls, the bottom of the roof terrace, under the floors and in basements and creep spaces. As a result, the air can no longer penetrate into the house, making it less drafty and more comfortable.
The spray foam is applied after finishing the windows, doors and roofs, frame, installation and electrical control and after installing all other systems behind the drywall.
