Cavi240 Type CFIS Cavicheck Fire Integrity Stop

These are compressible fire stops for use horizontally in cavity walls. Cavicheck Fire Integrity Stops are manufactured from rock mineral wool that has a non-combustible classification. The wool is enveloped within a polythene sleeve. Compressing and placing within the cavity secures the Type CFIS in position. A minimum compression of 10mm is necessary to friction fit the stop and importantly provides a functional relationship between surfaces. The use of an Arresting Barrier or Type CD Cavity Dropcloak is appropriate to introduce DPC measures in accordance with best practice.
