Cavity wall insulation
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.
When insulating cavity walls in new construction or renovation projects, an efficient and sustainable solution is crucial. Recticel Insulation offers with Eurowall® a range of insulation boards specifically developed for traditional cavity wall constructions. Thanks to the tongue-and-groove click system, a continuous insulation layer is easily created without cold bridges, resulting in optimal thermal performance.
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.
