What Is Foam Insulation?
Foam insulation is usually made up of materials that can generally be found in pillows and mattresses. It is available in the form of rolls or sheets and can be placed along the walls or in panels. It can also be loose and can be used to fill up loose space with the aid of a hose. Foam insulation may be priced higher as compared to fiberglass or cellulose insulation, but provides much better insulation as compared to these types of insulation materials. Foam Insulation Boards Foam insulation boards are prefabricated foam slabs, which can be cut according to the required size or made to fit walls, panels or cavities for insulation purposes. Most insulation companies provide foam insulation kits that include all the necessary materials. Although any homeowner can also install foam insulation boards, foam insulation specialists who can handle special equipment for installing it should be called in to perform these tasks. It is recommended that professionals carry out foam insulation. Spra
Foam insulation is a type of insulation that is sprayed onto walls or into small, difficult to reach places. Although it is more expensive than polystyrene and fiberglass insulation, which is installed in sheets or blocks, it is more effective in places like attics, where there may be unfinished walls or ceilings. Good, solid home insulation is crucial for reducing heating and cooling bills, and preventing damage from moisture and vermin. Polyurethane foam insulation is mixed with water, then sprayed under pressure from a pneumatic pump. As it mixes with oxygen from the air and the water dries, the foam expands, then hardens and cures within a few minutes. The volume of dry spray foam is five to ten times greater than that of wet spray foam. Spray foam is also self-adhering. This makes it possible to spray it under a floor without taking up the floor first, and it is much easier to apply to ceilings than sheets of insulation that must be glued or stapled into place.

The British Urethane Foam Contractors Association report of October 2000 says that:- “Spray applied polyurethane foams provide the ideal solution to insulate, stabilise and control condensation in buildings. PU foams have superior insulation values and greater vapour resistance than any other common insulation material and have a class 1 surface spread of flame. They contain no fibres, do not shrink, sag, settle, slip or turn to dust. BRITISH BOARD OF AGREEMENT approved foams are used as a repair medium on tiled and slated pitched roofs suffering from nail or nib fatigue.” “The product applied to the underside of the roof, bonds slates and tiles to each other and to structural or supporting timbers to replace the anchorage of fixing nails. It also seals the gaps between the slates or tiles, preventing the ingress of windblown rain snow and dust.” So there you have it…sprayed polyurethane foam applied to the underside of the slates or tiles and replacing the felt will lock – on the ro
