Final answer:
The '(180)' in Torchflex TP-180-FF indicates the weight of the base mat, 180 grams per square meter, which affects the material's performance. Torchflex refers to a modified bitumen roofing system, and 'TP' denotes that it is designed for torch-on application.
Step-by-step explanation:
The "(180)" in Torchflex TP-180-FF is a product specification that refers to the weight of the base mat used in the roofing material, measured in grams per square meter (g/m2). In this case, TP-180-FF likely uses a base mat that weighs 180 grams per square meter. This specification is crucial as it impacts the durability, strength, and performance of the roofing material in various weather conditions.
Torchflex is a type of modified bitumen roofing system which is designed to be heat-welded or torched onto a roof surface. The 'TP' in Torchflex TP-180-FF suggests that it is a torch-on product, and 'FF' may refer to a specific characteristic such as a 'fiber film' or 'fine finish' surface.
