Bradford Fireseal Fire Damper Strip is an insulation material specifically formulated to provide fire protection. It is manufactured by spinning a molten mixture of natural rock and recycled blast furnace waste products into fibres which are bonded with a thermosetting resin.

The product has remarkable resistance to shrinkage at temperatures encountered in fire conditions. This stability is well beyond that of normal rockwool or fibreglass materials. The product can be identified by its dark brown appearance. 15 pieces 750mm x 225mm
