Description
FIBERFLEX PLUS FAA is a waterproofing membrane made of distilled bitumen modified with SBS (styrene-butadiene-styrene) polymers that make it very elastic, resistant to thermal ageing and flexible at low temperatures.
The elastomeric compound ensures ease of application, reduced consumption of gas and has excellent adhesion properties that provide, when properly installed, superior bonding and tightness of all joints and overlaps.
40% of the upper face is coated in relief with THERMOADHESIVE STRIPS made of a special “hot melt” bituminous compound of elastomers and tackifying resins. The strips, when activated by light torching, form a homogeneous adhesive substrate for the simple application of insulation panels without the use of oxidised bitumen, mechanical fixations, mastics or any other kind of adhesives. Side and head overlaps of VapourControl Layer should be sealed by means of normal torching
The composite roofing system including FIBERFLEX PLUS FAA as underlay and FIBERFLEX HP MINERAL FAA as top layer has been tested and classified in category “EXT. F.AA”, in accordance with British Standard BS 476 Part 3:2004 “External Fire ExposureRoof Tests” (Report n°18900A).
