Holrow’s own G6R roof blanket is a durable PVC membrane for waterproofing the roofs of modular buildings. It can be bonded to the substrate using adhesive, which means a flame-free option for refurbishing dilapidated roofs while preventing disturbance to its occupants. G6R offers an aesthetically pleasing result and can also provide a robust base for paved or green roofs. We also supply compatible adhesive and flashings products.
(G12 offers a more heavyweight alternative.)
G6R is a light-grey, flame-retardant PVC sheet which is strengthened with the addition of a polyester mesh on one side. This mesh also offers an excellent face for bonding with adhesives. All blanket seams are manufactured using RF-welded joints.
G6R can be installed using quickly and easily using either:
Seal together adjoining modules on-site by overlapping the membranes from one building module to the next and hot-air welding them in place. Another option is to use SEAL-IT adhesive.
