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.
Xtratherm Insulation can be used in a wide variety of floor constructions including groundbearing concrete floors, suspended floors of pre-cast concrete units and suspended timber floors.
Xtratherm Insulation can be used in a wide variety of wall constructions including masonry cavity walls and solid walls lined internally.
