15mm Xtratherm Thin-r is a foil faced Polyisocyanurate (PIR) insulation board formed by a blowing process which generates rigid foam composed of fine cells filled with Pentane blowing agent trapped within the foam. Pentane has very good insulating properties and gives Thin-r superb insulating capability. Long term performance is ensured by the foil facings which are gas tight.

  • The thermal conductivity of Xtratherm Thin-r is among the lowest for commonly available insulation boards.
  • Xtratherm Thin-r boards are manufactured to strict dimensional tolerances, enabling the boards to be fitted tightly together. That reduces air leakage through the construction and associated heat losses through convection
  • Xtratherm Thin-r contains gas tight aluminium facings that form a low emissivity surface which, when facing a cavity reduces the heat loss through radiation, cutting the overall rate of heat loss.
  • Xtratherm Thin-r excellent lambda value and therefore low thickness allows constructions to be thinner than they would be with other insulation material
  • With the excellent thickness to performance ratio (R-value) of Xtratherm Thin-R less material is required to achieve the best performance levels asked for in the new building regulations.
Xtratherm Thin-r insulation board is suitable for use in:
  • floors
  • walls
  • roofs
Virtually all building elements can be insulated with PIR:
  • concrete slab
  • beam and block timber floors
  • masonry or timber framed walls
  • flat and pitched roofs
  • Xtratherm Thin-r is manufactured under ISO9001 assured quality system.
  • Xtratherm Thin-R is manufactured using Pentane as the blowing agent. Pentane is CFC/HCFC free with zero ozone depletion potential and a Global Warming Potential less than 0.01.
