XtroWall Plus 110

Partial Fill Cavity Walls

XtroWall Plus is a superior performance insulation with an Agrément declared lambda value of 0.020 W/mK and an enhanced Euroclass C fire rating. It is faced with a robust PIR aluminium foil and is available with engineered jointing to deliver improved Thermal Bridging detailing.

This lower Lambda improves U-Values and meets Zero Carbon standards, proving an excellent choice for passive and low energy builds. XtroWall Plus can achieve a passive U-Value of 0.15W/m2K in a traditional cavity wall. Building with Xtrowall Plus, a residual cavity is maintained, offering excellent protection against wind driven rain
