Extruded Polystyrene (XPS) tapered roofing insulation

XPS insulation is well known for its excellent compressive strength and thermal performance.  The robust insulation is resistant to the passage of water and is suitable for use in inverted roof applications.
  • Suitable for with single ply membranes, in an inverted roof below ballast or paving slabs or in a green / garden roof.
  • The thermal conductivity (lambda/λ-value) of XPS  is 0.033 W/m·K.
  • XPS is supplied in standard thicknesses of 1250 x 600 mm.
  • Strong and robust insulation
  • Excellent compressive strength - particularly useful in projects where weight loading must be considered
  • Good thermal performance
  • Water resistant
  • Lightweight boards are easy to handle
  • Moisture resistant due to the closed cell structure
  • Huge flexibility for standard or problematic roofs
  • Green Guide A rating
