Product Overview
Recticel Eurowall+ Full Fill Insulation T&G Board measuring 115mm thick and 1200mm × 460mm in size.
High-performance rigid polyisocyanurate (PIR) insulation board designed for full-fill masonry cavity wall applications. The board features a tongue and groove joint on all four sides to ensure precise interlocking, minimising thermal bridging and maintaining consistent insulation continuity across the wall cavity.
Each board is faced with a multi-layer gas-diffusion-tight foil, reflective on one side and alkali-resistant on the other, optimising thermal efficiency and long-term durability within the cavity environment. The rigid PIR core delivers excellent thermal performance with a declared conductivity of 0.022 W/mK, achieving strong U-value reductions in modern wall systems.
The 115mm thickness offers enhanced thermal performance for deeper cavity wall systems in energy-efficient construction.
Features & Benefits
- High thermal performance: Low thermal conductivity of 0.022 W/mK for energy-efficient cavity wall insulation.
- Interlocking edges: Tongue and groove joints on all four sides prevent thermal gaps and improve fit.
- Durable facing: Gas-diffusion-tight foil facings provide moisture resistance and surface integrity.
- Lightweight handling: Rigid PIR core allows easy cutting, lifting, and installation.
- Moisture control: Alkali-resistant facing minimises water ingress and maintains thermal performance.
- Thickness: 115mm board suitable for deeper cavity wall systems in energy-efficient construction.
Applications
- Full-fill cavity walls: Specifically designed for masonry cavity wall systems built to current regulatory U-values.
- Residential buildings: Ideal for domestic housing where full-fill insulation is required.
- Commercial developments: Suitable for schools, offices, and mixed-use buildings with cavity wall construction.
- Energy efficiency upgrades: Contributes to reduced heat loss and improved building energy ratings.
Installation Guidance
- Preparation: Ensure wall cavities are clean, dry, and free from mortar droppings.
- Board fitting: Insert boards with tongue and groove joints interlocked tightly and staggered in brick bond pattern.
- Securing: Retain boards with proprietary wall ties and retaining clips in accordance with Recticel guidance.
- Joint sealing: Ensure all edges are closely fitted to prevent air gaps or cold bridges.
- Protection: Keep boards dry on-site and covered until installed.
