COLVENT
The High Performance roof waterproofing system, COLVENT consists of a base sheet membrane semi-adhered using discontinuous self-adhesive strips and a cap sheet, which can be either heat-welded or glued using adhesive.
The COLVENT waterproofing system reduces the harmful effects of thermic cycles by distributing movement across the membrane. The COLVENT base sheet is easily installed directly to COLGRIP A insulating panels. Thus, you save energy and time by eliminating installation of support panels.
Flameless solution
COLVENT can be installed without using propane-fuelled equipment by
usingthanks to the self-adhesive cap
sheet membrane COLPHENE HR GR.
