Cavity Wall Insulation Board – PIR – Partial Fill Cavity Walls

Product Overview

This high-performance cavity wall insulation board is designed for use in masonry cavity wall constructions. Measuring 100mm thick and 1200mm x 450mm in size, it offers excellent thermal efficiency while being lightweight and easy to handle for quick installation.

The board features a rigid polyisocyanurate (PIR) core with low-emissivity foil facings on both sides, enhancing thermal resistance and contributing to improved wall U-values. Its moisture-resistant design ensures consistent performance over the building's lifespan.

Features & Benefits

• High thermal efficiency: Low thermal conductivity for superior insulation.
• Foil facings: Improves cavity reflectivity and reduces heat loss.
• Lightweight design: Easy to cut and fit, reducing installation time.
• Moisture resistance: Minimizes water absorption for reliable performance.
• Durability: Maintains dimensional stability and compressive strength.
• Suitable thickness: Perfect for 125mm+ cavities.

Applications

• Masonry cavity walls: Ideal for brick and block constructions.
• Partial-fill systems: Retains air gap while enhancing insulation.
• New builds and refurbishments: Suitable for both residential and commercial projects.
• Energy efficiency upgrades: Reduces heat loss, complying with building regulations.

Installation Guidance

• Preparation: Ensure cavities are clean and dry.
• Board placement: Fit between wall ties with tight joints.
• Fixing method: Use retaining clips to secure boards.
• Joint sealing: Butt edges tightly; seal as needed to prevent thermal bridging.
• Protection: Keep dry and avoid prolonged sun exposure.
