FIRECRUNCH K-ROOF

PASSSIVE FIRE BOARD Tongue & Groove TG19mm

FireCrunch K-Roof is a tongue and groove TG19mm sheeting for the purpose of preventing bushfire entry though the steel or tiled roof which will otherwise warp and peel off in extreme heat, being mainly only 0.48mm thick metal.

K-Roof underlay goes over the roof trusses under the steel roofing and meets BAL FZ and will prevent fire entry through the roofing and contributes to the overall sealed “Fire Box” principle designs of FCA which prevent external and internal ignition.
