Foamspray Technology rigid spray foam contractors secured another installation today – working on a residential garage roof. Foamspray Technology has seen a dramatic rise in this form of application over the past 2 years, where people are not ready to move out yet want and need more storage. The spray foam works by covering the roof of the garage with a seamless blanket of foam which on contacts rises and sets within 4 seconds, this then prevents air-bridging from the internal and external air cutting out condensation risk and making the space clean dry and usable. The application can usually be installed within a couple of hours and has a class 1 fire rating.

Polyurethane foam is sprayed onto the underside of tiled roofs to prevent tile slippage, where the fixings have rotted away or corroded. Its bonds to the inside of the tiles and locks them all into place preventing on- going roof repairs. As well as locking tiles and slates in place it provides an excellent thermal insulation barrier to the weather, strengthening roof and increasing air tightness.

Spray Foam made from plant sources such as castor oil or soya bean is also available and has good environmental credentials. It uses no HFC’s or fire retardants, nor is it a food source for mould and is vapour permeable. Sprayed onto walls, it expands to form a flexible foam blanket and is also useful for places that are awkward to reach. Suitable for roofs and floors and can be trimmed post application. The amount required to achieve the thermal value required depends upon the individual construction. It is widely used in the USA and is becoming more so here, particularly replacing mineral wool in timber frames.

Spray applied polyurethane foams unique selling qualities also have a significant effort on reducing airborne sound penetrating the property. It is also ideal for soundproofing interior walls and floors in conjunction with approval designs and around plumbing stack to reduce the sound of water rush.
