Manufactured only with printed lap lines and with no logos to the external face of the membrane to improve the architectural aesthetic of an open façade, Protect FrameSafe 5000 FR is an unbranded version of standard Protect FrameSafe FR, achieving the same Class A2-s1, d0 reaction to fire rating, when used as a system with Protect FR sealing tape.

Designed for use on the external side of the frame on open joint rainscreen cladding applications where gaps are included as a design feature, the membrane is suited for low, medium and high rise buildings over 11m or 18m in height or seven or more storeys, including those multi-occupancy, high risk buildings covered by the Building Safety Act.

The membrane was subjected to robust testing in an oven with artificial, accelerated UV ageing for 5,000 hours followed by heat ageing at 70 degrees for ninety days, in accordance with EN 13859-2.

The result of the aged testing showed no significant impact on tensile strength and elongation as well no change to the membrane’s W2 watertightness rating to BS EN 13111. The membrane’s strong UV stability means it can withstand exposure of up to six months during construction.

Both Protect FrameSafe 5000 FR and Protect FrameSafe FR feature an intricately woven glass fibre fabric with a uniquely developed waterproof and fire resistant coating. This can help improve the reaction to fire of the overall wall structure when used to integrate with the façade.

FrameSafe FR and FrameSafe 5000 FR as its unprinted counterpart, exceed the requirements detailed within the Building Regulations for all countries within the UK and in Ireland.
