Xtratherm Cavity Wall Insulation

We stock and supply Xtratherm Cavity Wall Insulation throughout Ireland and have experts on hand to help you choose the right Xtratherm Cavity product for your needs.

Our range of Xtratherm Cavity Wall Insulation products includes Xtratherm Cavity Closer in various thicknesses, Xtratherm XtroWall, Xtratherm Internal Corner Insulation (CT/PIR), Xtratherm External Corner Insulation (CT/PIR), Xtratherm Cavity Internal and External Insulation and Xtratherm Cavity Tongue and Groove models.

Xtratherm CavityTherm is a built-in insulation system that achieves ultimate U-values within traditional wall constructions. It doesn’t require an engineer’s report, meaning that minimal heat energy is lost through the walls.

It provides an affordable and practical solution when looking to buy best performance wall insulation.

We supply this to both trade and non-trade customers nationwide and our friendly team of experts can help advise you as and when required when selecting your ideal insulation product. Just email us at sales@mybuildingsupplies.ie or call us on 0818 888 000 anytime.
