Thermal laminates

Thermal laminates

Sometimes it is desirable to bond a layer of another building material to an insulation board, creating a thermal laminate. Examples of thermal laminates include plasterboard, to receive waterproofing or other decorative finish, and cementitious board, for fire protection.

The thermal properties of the insulation are retained, while enhancing the performance characteristics of the product as a whole and increasing the range of applications in which the insulation can be used.

Why is extruded polystyrene insulation used in thermal laminates?

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.

Polyfoam XPS supplies one thermal laminate product in its own range. Polyfoam 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. It offers the following benefits:

  • Integral weather resistant facing.
  • Capable of solving many design problems.
  • Excellent thermal performance.
  • Structurally stable.
  • Easy to install one-piece facing and insulation solution.

What other Polyfoam XPS products are suitable for thermal laminate applications?

Conversion companies seeking to provide thermal laminates can take advantage of Polyfoam Laminating 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.
