Meir Roofing

Cellular glass is made from pure glass, expanded during manufacture and formed into slabs which are inorganic, resistant to attack by birds and vermin, almost impermeable to water, will not gain moisture by vapour diffusion, will not rot or decay and is non-combustible. It can be laid without a vapour barrier, provided that the joints are sealed in bitumen according to the manufacturer’s instructions. Cellular glass provides a stable base for mastic asphalt and fully bonded built-up roofing. When mastic asphalt is applied, two layers of loose laid non-bituminised paper are required between the slabs and the sheathing felt isolating membrane to prevent adhesion of the asphalt. Slabs are available in constant thicknesses or tapered to provide falls and suitable for roofs, floors, and walls and is available in cut to falls.
