Non-Impregnated Gapseal FR

TN220 incorporates the very best quality open cell fire resistant foam bonded to a unique high performance graphite intumescent material. Achieves class ‘0’ spread of flame as specified in British Building Regulations. It does not flame but slowly degrades and expands to leave an inert self insulating char. It is available to seal gaps from 7 to 150 mm with a fire integrity of up to 2 hours.


TN220 is designed for ease of installation. A cost effective solution for stopping flexible gaps in fire rated building elements in internal applications.
