70mm Unilin Thin-R XT/CWP Cavity Wall Insulation Board

70mm Unilin Thin-R XT/CWP Cavity Wall Plus (T&G) represents a high-performance thermal solution engineered for traditional masonry structures requiring partial fill cavity wall insulation. This advanced cavity wall insulation board features precision-engineered tongue and groove joints alongside pre-formed corner components, delivering consistent thermal performance and substantially reducing thermal bridging throughout the installation.

Delivering exceptional thermal credentials, the 70mm Unilin XT/CW Plus Cavity Wall (T&G) achieves a Lambda value of 0.021 W/mK, translating to superior U-Values and alignment with Future Homes standards. This system provides robust protection against wind-driven rain whilst maintaining a residual cavity, making it particularly suitable for passive and low-energy construction methodologies. The combination of technical performance and practical design makes this an excellent choice for sustainable building projects.
