CTF-06 – EPS/PIR Foil Faced

CTF-06 is a ‘hybrid’ system comprising of tapered EPS and uniform thickness foil faced PIR overlay used in warm roof applications to create suitable falls under any compatible single ply membrane in a mechanically fixed system. This system provides excellent thermal performance and any required fall. The use of a foil faced PIR overlay also negates the use of a separation layer under the single ply membrane. (Check with relevant membrane manufacturer).
