Home Insulation Xtratherm Insulation


Xtratherm is a foil-faced Polyisocyanurate (PIR) Insulation Board.

The PIR core of Xtratherm Insulation boards has an extremely low thermal conductivity. The foil laminate facings of Xtratherm boards can also contribute to improved thermal performance: the low emissivity surface of the reflective foil can cut radiation heat transfer across an adjoining air space.
