Celotex can comply with the thermal requirements of building regulations when used correctly, so it will fully meet the needs of almost any building professionals. It is up to 100 per cent more efficient than most mineral fibre products in terms of thermal performance.

It’s an extremely versatile material, suitable for use with floor, wall and roof installations: whatever project you’re working on, Celotex will work effectively. It is lightweight and easy to cut, making it perfect for anyone working under a tight time-frame who can’t afford to be delayed. There are few insulation boards that are more flexible and easier to work with.

When compared to the BRE Green Guide, Celotex achieved an A+ rating, meaning that it provides a lower environmental impact than most PIR insulation. GA3000 recently gave the best reaction when tested in accordance with new European standards of fire safety.
