Firebreak 55 Fire Resistant Non-Setting Putty is made from silicone based ablative polymer with additional fire resistant additives, and is designed to reinstate the fire resistance of small cable service penetrations through walls.

Description

Firebreak 55 Fire Resistant Non-Setting Putty is a silicone based ablative polymer with additional fire resistant additives. It is designed to maintain the fire resistance of walls when penetrated by electrical cabling passing through small openings. Under fire conditions the fire resistant fillers combine to form a dense block of fire resistant char that restricts the passage of smoke and fire.

The non-setting nature of the material allows for easy future modification of the fire seal enabling the removal of existing cables or introduction of new cables whilst reusing the Putty to reinstate the fire seal.

Fire testing has been conducted in conjunction with a range of cable service penetrations through fire compartmenting 100mm thick flexible (plasterboard) partitions allowing the results to be applied to both partitions and masonry walls of equal or greater thickness.
