Product type Boards

Our cellular glass insulation boards measure 1200x600mm, and have a glass fleece facing, to aid adhesion and bonding. Boards are used throughout the entire internal and external building envelope, and are particularly useful upon profiled metal roof decks. The board insulation core comprises of cellular glass and so meets Euroclass A1 standards, only the thin fleece facing adds a combustible element, resulting in the overall board product being rated as E. The boards are popular for larger areas and faster installation.

Grade S3

With a thermal conductivity (lambda value) of 0.045 W/(m·K) and a max compressive strength of 900 kPa, FOAMGLAS® S3 is the insulation of choice for floors and roofs with a load-bearing capacity suitable for mid-sized vehicles and maintenance machines. Compressive strength requirements for any application should always be confirmed with a structural engineer to ensure the correct product specification.
