IKO TGX Underlay is a glass-fibre–reinforced, SBS-modified bitumen membrane, designed for torch-on application in both new-build and refurbishment roofing. It works in tandem with the TGX Capsheet to form a durable, built-up roofing system offering excellent dimensional stability and high-temperature performance 

Features
