Product Information
We manufacture a wide range of roofing insulation products to meet the various required applications. We work in conjunction with roof engineers and design teams to offer the complete design and supply package.
The main consideration for a specifier is to decide which weatherproof finish is required and then build up a compatible system to accommodate this, coupled with the need to take into account the effect of heat on the construction both during construction and after completion.
Other important issues involve the selection of a compatible adhesive, sealant and or mechanical fixing to bond the weatherproof membrane plus the control of water vapour. S and B EPS offer a wide range of systems that are available in a wide range of densities and thicknesses with, a square edge, shiplap or tongue and grooved edge detail.
Cut-to-falls insulation offers the ideal solution to refurbishment and ponding problems on existing buildings. Uniform thickness boards are suitable for roofs which have an existing fall incorporated and are unaffected by bacteria, fungi or moulds and maintain their thermal efficiency throughout the life of the building.
Compatibility:
S and B EPS roof insulation can be adapted to suit a wide range of applications including weatherproof roof membranes. Unlaminated expanded roof boards are suitable for use under EPDM/ butyl rubber roofing and some plastic type single layer membranes. Where the membrane is plasticised, a separating layer of fleece is required between the polystyrene and the membrane. Pre-felted boards are suitable where built up felt or high-performance roofing felts are used with mastic asphalt roofing, but care must be taken when laying in very high ambient temperatures (technical information available on request).
