100mm Unilin XT/CW Partial Fill Cavity Insulation

The 100mm Unilin XT/CW Partial Fill Cavity Wall (T&G) system features engineered tongue and grooved joints with pre-formed corners for seamless insulation continuity and reduced thermal bridging.

Engineered for traditional masonry walls, this 100mm cavity insulation system meets rigorous thermal performance standards. It delivers superior thermal efficiency whilst preserving a residual cavity space, offering robust defence against wind-driven rain penetration.

The XT/CW is supplied in both Square Edge and Tongue & Grooved versions. The 100mm Unilin XT/CW was previously marketed as 100mm Xtratherm XT/CW.
