Engineered for Cavity Walls

EcoTherm Eco-Cavity Wall Insulation Board is designed for partial-fill masonry cavity walls. The foil-faced PIR core improves thermal resistance while maintaining a compact board profile. It offers reliable insulation where cavity space is limited.
The foil-faced PIR core delivers consistent thermal resistance while maintaining a slim profile. It fits securely between wall ties, reducing cold spots and improving long-term cavity performance.

Proven Thermal Performance

The board provides a thermal conductivity of just 0.022 W/m·K. Its closed-cell PIR core and reflective foil surfaces help meet Part L energy targets in residential and commercial construction.

Sustainable and Durable

This board is built to last, with strong compressive resistance and low water absorption. It supports long-term building fabric performance and contributes to energy-efficient design without compromising structure.

Compact Coverage

Each board covers 0.54m² and is easy to install in tight or narrow cavity spaces. Its small format improves fit in challenging layouts and reduces wastage during installation.

Compliant and Certified

Manufactured in line with BS EN 13165 and certified by the BBA, this product meets key UK building regulations. Suitable for residential and non-residential builds.
