Introducing 60mm Unilin Xtroliner XO/CW Partial Fill Cavity Wall Insulation Board a forward-thinking partial fill wall insulation system that integrates durable facings, precision-engineered jointing elements, well-defined corners, and a certified lambda value of 0.021 W/mK.
This reduced lambda value significantly enhances U-Values and aligns with Future Homes standards, making it an exceptional choice for passive and energy-efficient constructions. With 60mm Xtroliner XO/CW Partial Fill Insulation, achieving a remarkable passive U-Value of 0.15 W/m2K within a conventional cavity wall is possible. Embracing XO/CW (T&G) during construction maintains a residual cavity, which delivers outstanding defense against wind-driven rain.
