• Good thermal performance: λ = 0.022 W/mK
• Easy and fast installation
• Can help to achieve 0.18 U-value in 100mm cavities
• Tongue and groove rebate minimises thermal bridging

Cavitys: Recticel Eurowall + insulation boards are versatile and ideal for various applications in both residential and commercial construction. They are commonly used in cavity walls, pitched roofs, floors, and timber frame constructions to provide excellent thermal insulation, enhance energy efficiency, and maintain comfortable indoor temperatures. Lightweight and easy to handle, Eurowall + boards are suitable for new builds, renovations, and retrofit projects. Their robustness and moisture resistance make them perfect for exterior applications, ensuring long-lasting thermal performance and comfort.

How does the thermal conductivity of Recticel Eurowall Cavity Wall Insulation compare to other insulation products?

Recticel Eurowall boasts a low thermal conductivity of 0.022 W/mK, which is highly efficient compared to many other insulation materials. This low lambda value ensures better heat retention and improved energy efficiency for buildings

Is Recticel Eurowall Cavity Wall Insulation suitable for both new builds and renovations?

Yes, Recticel Eurowall is suitable for use in both new construction projects and extensions. It is designed to fit easily between brick ties in masonry cavity walls, making it versatile for different building applications​

What air gap is required between insulation and breather membrane?

This should be confirmed in the membrane manufacturer's BBA certificate, though 25mm to 50mm is typical.

Is a vapour control layer (VCL) required in a floor insulation application?

In addition to the damp proof membrane (normally a 1200-gauge polythene sheet below the insulation), a 500-gauge polythene VCL should be laid over the insulation. Where a concrete slab or a screed is to be poured on top, the VCL will also protect the foil face of the board from alkalis within the concrete, and stop poured concrete opening board joints and causing a thermal break.

Can PIR insulation boards be used directly below flooring tiles?

No, PIR insulation boards should not be used directly below flooring tiles, a suitable substrate such as screed should be used to distribute the load and prevent movement and cracking of the tiles.
