CTF-07 – EPS/PIR Bitumen Faced

CTF-07 is a ‘hybrid’ system comprising of tapered EPS and uniform thickness bituminous face PIR overlay used in warm roof applications to create suitable falls under any compatible bituminous membrane system. This system provides excellent thermal performance and any required fall. The use of a bituminous faced PIR overlay also facilitates the use of torch-on membranes. (Check with relevant membrane manufacturer).
