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.


100mm Xtratherm Thin-r insulation board characteristics:


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:





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.
