Celotex FF4075 75mm Unit price £ (£0.00 inc VAT) See below for multi-buy discounts*  







Product Summary

Celotex FF4000 is a product range aimed specifically at the under floor heating market where the increased compressive strength of the board provides better dimensional stability and resistance to site traffic during installation whilst the foam structure ensures better pipe clip retention.

Where you are not using clips we would recommend using the normal Celotex GA4000 Boards which have better availability and are cheaper. The thermal performance of the boards is the same.

We can see there is no performance difference from a insulation standpoint . It is just a question of different board densities.
