Excel® FM Flame Free Waterproofing System

Excel® FM Flame-Free waterproofing system has been developed to safeguard client and contractor confidence through the reassurance of long term 30 year Axter insured system guarantees, indemnifying the building owner’s liability in the unlikely event of failure arising from material, design and workmanship. Additional independent insurance backed insolvency protection for Axter's materials, and the workmanship of the accredited roofing contractor, is also available for 10 years in respect to Platinum Guarantees.

Excel® FM is a high-performance single layer mechanically fixed ALPA® polymer modified bitumen waterproofing system. The Excel® FM capsheet provides exceptional age resistance characteristics, mechanical strength, point load resistance and dimensional stability due to its composite reinforced core and unique ALPA® binder. Technological development and advanced polymer modification create a highly flexible robust material, with a safe and secure response to hot air welding methods at laps and joints.

Engineered for fast track mechanically fixed installation without the need for torch-on installation, the Excel® FM Flame Free polymer modified bitumen capsheet provides an enhanced performance alternative to single ply synthetic membranes. All laps and joints are sealed by hot air welding method to ensure a visible 2mm bead of bitumen is achieved in accordance with BS 8217 Reinforced bitumen membranes for roofing – Code of practice. Detailing is also completed using Neo-Bitumen™ flame free underlayer technology using hot-air welding techniques.

The system must be installed by an accredited installer that has successfully completed Axter's Flame Free system upskilling course.
