XtroWall is an innovative partial fill wall insulation system incorporating robust facings, engineered jointing details, performed corners and a certified lambda of 0.021 W/mK. This lower Lambda improves U-Values and meets Zero Carbon standards, proving an excellent choice for passive and low energy builds. XtroLiner Partial Fill Cavity Wall XO/XW can achieve a passive U-Value of 0.15 W/m²K in a traditional cavity wall. Building with Xtrowall, a residual cavity is maintained, offering excellent protection against wind driven rain.
