CTF-10 – Stone Wool/PIR Foil Faced

CTF-10 is a ‘hybrid’ system comprising of tapered foil faced PIR and uniform thickness stonewool underlay used in warm roof applications to create suitable falls under any compatible single ply membrane system. Providing superb acoustic/thermal performance and the required fall, the system is mechanically fixed with thermally broken fasteners.
