Fixing and buying guide

What this product is and who it is for

Ecotherm Rigid PIR Insulation is a rigid polyisocyanurate foam board for thermal insulation in building applications. It is suitable for builders, contractors and serious DIY customers undertaking new build, refurbishment or retrofit insulation work. The lightweight rigid foam format makes it easier to handle and install compared to heavier alternatives, whilst maintaining load-bearing capability through its 175 kPa compressive strength rating.

Sizing, pack contents and board dimensions

Each board is supplied at 1200 x 2400 x 25mm. This single board format allows straightforward handling and installation. The 25mm thickness is suitable for typical insulation applications where moderate thermal resistance is required. Confirm your project's thermal and structural requirements before ordering to establish how many boards you need.

• Board dimensions: 1200 x 2400 x 25mm
• Material: Rigid polyisocyanurate (PIR) foam
• Supplied as individual boards

Thermal and structural performance

The board delivers thermal conductivity of 0.022 W/mK, providing consistent thermal performance across floor, wall and roof applications. Compressive strength is rated at 175 kPa, which supports structural load requirements in typical building applications. BBA certification backs the product's thermal performance specification, giving confidence to architects, builders and merchants specifying insulation performance.

• Thermal conductivity: 0.022 W/mK
• Compressive strength: 175 kPa
• BBA-certified for specification assurance

Pre-installation checks and preparation

Before installation, confirm that the board dimensions and 25mm thickness are compatible with your application and that your project's thermal resistance requirements are met by this product's 0.022 W/mK performance. Check that the installation surface is clean, dry and level. Ensure adequate ventilation and follow building regulations and any specific installation guidance for your application type, whether floor, wall or roof. Store boards in a dry location prior to installation.

• Verify board thickness and dimensions suit your application
• Prepare installation surface: clean, dry and level
• Check local building regulations and installation requirements
• Store in dry conditions before use
