foam boards

Postby yorkshirepudding » Mon Jun 26, 2017 7:27 pm

I had my floor insulated with foam boards last year. I employed someone to put them in but sourced the material myself. The supplier said the boards were fire retardant and directed me to their website for written reassurance. In the wake of that dreadful fire in Kensington, I thought I would test a small piece of the foam which I had a spare of in the cupboard. Straight away it melted into a liquid which caught fire. There was no fire resistance. Can I take action against the supplier or should I try to trace the manufacturer to put right?

Your contract was with the supplier. Your claim is against them.

What sort of boards were they and were they installed under a screed?

I'm assuming this is a suspended wooden floor? With wooden timbers, boards and joists? You need to check the specific model you purchased and its fire rating. Not all "foam" boards (I'm assuming it is Polyisocyanurate and has a bonded foil facing on both sides) is fire rated.

Be aware that "Fire Retardant" does not mean non-combustible. Fire retardant panels will have a BS 476 Class 0 fire rating. They will burn.

The other thing to be aware of are that these boards are fire retardant as sold. Once cut the fire retardancy is compromised.

I'm not convinced they would be fit for purpose if that was true. The product is designed to be cut, In any case its the foil backing that provides the fire protection, not the foam itself.
