Sometimes the performance characteristics of insulation materials alone are not enough for certain applications. It can be desirable, therefore, to bond a layer of another material to the insulation board. A laminate may act as a substrate for:
- receiving waterproofing or other decorative finish (e.g. plasterboard to be decorated),
- providing fire protection (e.g. for soffit lining applications), or
- taking fixings that the insulation isn’t strong enough to hold.
All of this, while retaining the thermal performance of the insulation.
Extruded polystyrene (XPS) is a versatile insulation material. It is unfaced (i.e. is not manufactured with, for example, aluminium foil or glass tissue faces like other rigid insulation types) and does not absorb moisture, meaning a variety of laminates can be bonded to it for numerous applications.
Conversion companies seeking to provide thermal laminates can take advantage of Polyfoam XPS’s Laminate Board. Available in 1200 x 2400mm or 1220 x 3000mm sizes, it is manufactured to even tighter tolerances than normal for a precise match to the dimensions of the laminate. Where required, all of the necessary technical data is available to assist the converter in achieving third-party certification.
Polyfoam XPS supplies one thermal laminate product in its own range. Upstand Board features a cement particle board bonded to extruded polystyrene insulation, for use around the perimeter of flat roofs to help address linear thermal bridging heat losses.
