Commercial Spray Foam Insulation – The most efficient insulation per thickness for Commercial Buildings
Websters Insulation Ltd has over 35 years of experience in the application of polyurethane spray foam insulation to commercial buildings across the UK.
Polyurethane Spray Foam Insulation is widely used in industrial and commercial settings, in structures such as: factories, warehouses, exhibition halls, showrooms, football stadiums, offices, industrial units, shops, municipal/charitable/ religious buildings.
It provides the ideal, cost effective solution for insulation and condensation problems on commercials buildings and can be applied to virtually any surface. It improves the working environment and reduces fuel costs, and may also be used for asbestos encapsulation in older buildings.
In both new and existing buildings, the foam is applied to the underside of the steel, aluminium or asbestos roofs and walls to a specified thickness. A K-value of 0.023 W/mK gives unrivalled insulating benefits, reducing U-values from ~6.0 W/m²K with as little as 75mm of foam. A U-value of ~0.48 W/m²K is achieved with as little as 50mm of foam.

The finished surface is non-toxic and odourless, it has low water absorption and high resistance to chemical attack. It may also be high-pressure jet washed. All spray foam insulation materials used are made to BS 476 Part 7 fire retardant standards. Where additional fire protection is required, Class zero standard can be provided. It is also possible to coat the surface with emulsion paints or chlorinated rubber vapour barriers.
