50mm Unilin Xtroliner XO/CW Cavity Wall Insulation

Discover the 50mm Unilin Xtroliner XO/CW Partial Fill Cavity Wall Insulation Board, an innovative partial fill wall insulation solution featuring robust facings, precision-engineered joints, carefully designed corners, and an impressive lambda value of 0.021 W/mK.

The low lambda value substantially improves U-Values and meets Future Homes standards, making it ideal for passive and energy-efficient building projects. Using 50mm Xtroliner XO/CW Partial Fill Insulation, you can achieve an excellent passive U-Value of 0.15 W/m2K in a standard cavity wall. The XO/CW (T&G) profile preserves a residual cavity during installation, providing superior protection against wind-driven rain penetration.

Guidelines for Handling, Cutting, and Storage

1. Position 50mm XO/CW on a clean, dry, level surface above ground level, keeping it covered and protected from weather exposure.
2. Note that polythene wrapping alone does not provide adequate protection for the insulation against outdoor conditions.
3. Take care to shield the Partial Fill insulation Board during both storage and the building phase.
4. Always use suitable Personal Protective Equipment (PPE) when working with the insulation.
