Polyglass announces the new Velociflex high wind-resistant roof assembly system. Independently tested, the Velociflex system provides for high-speed wind protection up to 270 psf (pounds/square foot).
The core of Velociflex is two or three plies of reinforced modified bitumen membranes. Suitable for new or re-roofing projects, this multi-ply system comprises of a mechanically fastened base sheet, optional interply, and a heat-welded or cold-applied cap sheet. According to the manufacturer, Velociflex is ideal for both steel and concrete decks.
The self-venting Velociflex system’s “loose-laid,” mechanically attached base sheet reduces the likelihood of blistering from substrate to membrane. Attached at the seams only, it also limits material and labor costs. Plus, the watertight system acts as a temporary roof once base sheet seams are heat-welded. Fast and efficient to install, the Velociflex system dries in fast, so projects can proceed with phased construction before cap sheet installation.
Installed with a Polyfresko G cap sheet with initial Solar Reflective Index 96, the Velociflex system complies with 2016 Title 24 Part 6 Cool Roof Requirements and is ENERGY STAR Certified. The Velociflex system is also compatible with a variety of SBS and APP cap sheets from Polyglass, including Elastoflex, Polyflex, and Elastoshield membranes.
