Foil insulation is an innovative way to insulate walls in a building. They provide better and lasting thermal insulation without decreasing the air quality as wool insulation does. 

Below are some reasons why we recommend Actis Boost R Hybrid to insulate walls:

Cost-effective in the long run: Cost highly influences our choice of insulation. Foil insulation rolls cost almost as much as wool insulation when you include the charges of installation and labour. Foil insulation rolls are very easy to use, handle and install. 

Furthermore, unlike wool insulation, foil insulation does not release harmful fibres into the air. It helps improve air quality 

Performance: Actis Boost’R multifoil insulation gives superior thermal insulation to walls. It combines the properties of a breather membrane and thermal insulation in one easy-to-use product. It will help you meet the required U-values at reduced thickness, saving internal space. 

Installation: Because of its dual performance, multifoil insulation reduces the number of steps required to meet Building regulations. It reduces the number of installation steps, saves time and cost on labour. It can also be used in conjunction with any other insulating material.
