130mm PIR Insulation Board 2400mm x 1200mm ( 8″ x 4″ )

Our 130mm PIR Insulation Board, measuring 2400mm x 1200mm (8′ x 4′), is a premium, multi-purpose thermal insulation solution designed for exceptional energy efficiency in UK construction projects. This high-performance rigid polyisocyanurate (PIR) board is engineered to significantly reduce heat loss, making it an essential component for achieving stringent Building Regulations compliance and long-term energy savings.

Featuring a robust closed-cell PIR foam core, each board is faced on both sides with low emissivity composite aluminium foil. This advanced construction not only provides outstanding thermal performance with a low thermal conductivity but also offers enhanced vapour resistance, contributing to a more airtight and moisture-controlled building envelope. Lightweight and easy to handle, our 130mm PIR insulation boards are straightforward to cut and install, ensuring a quick and efficient build process for both trade professionals and DIY enthusiasts.

Key Features and Specifications

• Material: High-performance rigid polyisocyanurate (PIR) foam core.
• Dimensions: 2400mm (Length) x 1200mm (Width) x 130mm (Thickness) (8′ x 4′).
• Thermal Conductivity (Lambda): 0.022 W/mK, ensuring superior thermal efficiency.
• Facings: Low emissivity composite aluminium foil on both sides for improved thermal performance in cavity air spaces and vapour resistance.

• Fire Performance: Generally achieves Euroclass F Reaction to Fire classification (BS EN 13501-1) for the board itself, with enhanced performance when part of a tested system.
• Environmental: Zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
• Certifications: BBA certified for defined applications, helping meet current UK Building Regulations (e.g., Part L).
• Ease of Use: Lightweight, durable, and easy to cut, handle, and install.

Applications

This versatile 130mm PIR insulation board is suitable for a wide range of applications across various building elements, providing excellent thermal performance and contributing to a comfortable, energy-efficient environment. Common uses include:

• Floors: Ideal for insulating solid concrete floors (above or below slab), suspended timber floors (between or above joists), and enhancing the performance of underfloor heating systems.
• Walls: Effective in masonry cavity walls, timber frame walls, steel framed systems, and for internal dry lining applications, significantly reducing heat transfer.
• Roofs: Perfect for both pitched roofs (between and over rafters) and warm flat roof constructions (above the structural deck), helping to achieve low U-values and prevent condensation.
