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.
- Achieves 0.15 U-Value in 150mm Cavity
- Improved Lambda value 0.020 W/mK
- Enhanced Euroclass C fire performance
- Engineered Jointing
- Corner Panels & Cavity Closers: Reduced Thermal Bridging
