Insulation for Cavity Walls
Recticel delivers cavity wall insulation solutions for new construction and renovation projects, designed to improve windtightness and reduce thermal bridging.
Enhancing Energy Efficiency with Recticel's Eurowall + and Eurowall Cavity.
In the quest for more energy-efficient homes, cavity wall insulation remains a crucial solution.
What is Cavity Wall Insulation?
Cavity wall insulation is a material built into a wall cavity to improve energy efficiency and reduce of heat lost through the wall.
Introducing Eurowall + and Eurowall Cavity
Eurowall + stands out as insulation board that's evolved the way we insulate our homes.
This PIR insulation board is intended for full-fill masonry cavity walls with a 10 mm clear cavity. For example, a 90 mm board installed in a 100 mm cavity is positioned against the inner leaf, leaving a 10 mm cavity on the external side.
Eurowall Cavity
Eurowall® Cavity is a specialist solution for cavity walls, featuring precision-cut straight edges to help minimise gaps between boards. It can also be used in partial-fill cavity wall insulation, where a 50 mm residual cavity is left, compared with the 10 mm residual cavity in full-fill applications.
Supporting Energy-Efficient Building for Tomorrow
Recticel’s extensive range of PIR insulation boards are engineered to support compliance with the UK’s upcoming Future Homes Standard. Designed to enhance thermal performance across new builds and renovations, these products align with the UK’s evolving commitment to greener, more energy-efficient construction. With certified performance data and low environmental impact, they help future-proof buildings while supporting national sustainability goals.
The Role of U-Values in Optimising Cavity Wall Insulation Performance
U-values quantify the thermal transmittance of a building element, expressed in W/m²·K, and are a critical parameter in cavity wall insulation design. Achieving lower U-values through appropriate insulation selection reduces conductive heat transfer, enhances envelope performance, and ensures compliance with regulatory standards such as Part L of the Building Regulations. In cavity wall applications, accurate calculation of U-values - accounting for material properties and thermal bridging - supports long-term energy efficiency and occupant comfort. This makes U-values an essential benchmark for evaluating and optimising the thermal performance of insulated wall systems.
