G12 is Holrow’s own PVC roof blanket, providing a long-lasting, high-quality waterproof membrane for the roofs of modular/portable buildings and cabins. Since it can be installed using adhesive, it offers a flame-free reroofing option which extends the life of the building and avoids disturbing its occupants. It offers an attractive finish which can also form the base of a paved or green roof. We also supply compatible adhesive and flashings products.
(G6R offers a more lightweight option.)
G12 roof membrane is made from light-grey flame-retardant PVC laminate reinforced with a polyester mesh interlayer (which provides dimensional stability plus superb bonding for adhesives). All seams are manufactured with RF-welded joints.
G12 roof blankets are quickly and easily installed using:
Adjoining building modules can be sealed together on-site by overlapping the roof blanket onto the next module and using standard hot-air welding techniques. Alternatively, you can use SEAL-IT.
