Technical specifications:

External thermal insulation. Patented ETI solution. Unique building system.

The ISOLEXCEL solution provides comfort and energy savings. It can be used to renew the appearance of a building by modernising it using modern materials in a wide range of profiles, tree species and trendy colours.






ISOLEXCEL is an insulating material that has all the components needed for your external insulation. Fully adaptable, it can be applied to any building, whatever the support: breeze blocks, brick, concrete, stone, timber, etc. It can be used both for new builds and refurbishments.
