Commercial Spray Foam Insulation in London – The most efficient insulation (per thickness) for Commercial Buildings
At, Websters Insulation Ltd, we have over 35 years of experience in the application of polyurethane spray foam insulation to commercial buildings across London.
Polyurethane Spray Foam Insulation is widely used for industrial and commercial buildings, such as:
- Factories
- Warehouses
- Offices
- Showrooms
- Industrial units
- Exhibition halls
- Football stadiums
- Shops
- Municipal/charitable/religious buildings
It offers an ideal, cost effective solution for issues relating to insulation and condensation in commercial buildings all around the London area. Spray foam insulation improves the working environment whilst reducing fuel costs. Furthermore, it can be applied to almost any surface and can even be used for asbestos encapsulation in older buildings.
For both new builds 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 provides unmatched insulative properties, reducing U-values from ~6.0 W/m²K with as little as 75mm of spray foam. A U-value of ~0.48 W/m²K is possible with as little as a 50mm application of foam.
| Foam Thickness (mm) | K – Value | U – Value |
| 25 | 0.023 | 0.840 |
| 50 | 0.023 | 0.437 |
| 75 | 0.023 | 0.295 |
| 85 | 0.023 | 0.264 |
| 100 | 0.023 | 0.225 |
| 130 | 0.023 | 0.173 |
The finished surface is non-toxic as well as odourless, with low water absorption and high resistance to chemical attack. The surface may also be high-pressure jet washed for maintenance.
All spray foam insulation materials we use are made to BS 476 Part 7 fire retardant standards. Class zero standard can be provided where additional fire protection is required. Additionally, the surface can be coated with emulsion paints or chlorinated rubber vapour barriers if required.
