A completely flame-free multi-layer specification providing fire safety whilst delivering durability and reliability.
The Force system is extremely versatile and can be adapted to suit the exact requirements of the roof, ensuring the best, most appropriate system is specified. Application flexibility and performance characteristics make Force ideal for use on all construction types as well as an overlay system for cost effective roof renewal.
Suitable for all roof deck types.
High performance SBS-polymer-modified reinforced bitumen membrane. Engineered to guarantee durability, Force self protected systems have exceptional ageing characteristics and a proven track record of excellent performance.
As the name suggests, Force has been developed to be strong and long lasting, and designed to withstand the rigors of the modern construction environment. The membranes have been manufactured to incorporate enhanced polymer content and high strength reinforcements that provide outstanding material durability, flexibility and workability.
Force systems guarantee a complete specification solution comprising Air and Vapour Control Layers (AVCLs), flat board thermal insulation (tapered solutions available, please contact Axter Ltd accordingly), underlayers and robust capsheets self-finished in a choice of colours, providing a versatile and robust finish to suit both new construction and refurbishment projects.
