Alumasc鈥檚 Swisslab external wall insulation was used in a refurbishment of Tarmac鈥檚 UK headquarters in Wolverhampton

Some 2,500m2 of Swisslab was installed on the project with 1.5mm Silkolitt silicone render finish in cream along with Phenolic insulation boards.

In addition, 50mm Phenolic boards were used on the main structure, narrowing to 20mm boards around the windows. Alumasc said that the U-values of the external walls had been reduced from 1.35w/m2K to 0.31W/m2K. The product was chosen because an EWI system could be installed over the existing substrate.
