70mm PIR Insulation Board 2400mm x 1200mm ( 8″ x 4″ )

70mm PIR Insulation Board 2400mm x 1200mm (8′ x 4′) – High-Performance Thermal Solution

Optimise your building’s energy efficiency with our 70mm PIR Insulation Board, measuring a standard 2400mm x 1200mm (8′ x 4′). This high-performance rigid polyisocyanurate (PIR) insulation board is engineered to deliver exceptional thermal performance, making it an essential component for modern UK construction projects. With its low thermal conductivity and durable foil facings, it significantly reduces heat loss, helping to achieve stringent U-values and lower energy bills across a wide range of applications.

Key Features and Specifications

• Material: High-performance rigid Polyisocyanurate (PIR) core.
• Dimensions: 2400mm (length) x 1200mm (width) x 70mm (thickness).
• Coverage: Each board provides 2.88m² of insulation.
• Thermal Conductivity (Lambda): Excellent 0.022 W/mK for superior thermal efficiency.
• R-Value: Approximately 3.15 m²K/W, ensuring robust insulation performance.
• Facings: Low emissivity composite foil facings on both sides enhance thermal performance and act as a vapour barrier.
• Installation: Lightweight, easy to cut, handle, and install, saving time on site.
• Moisture Resistance: Foil-faced construction provides good resistance to moisture.
• Certifications: BBA approved and achieves an A+ rating in the BRE Green Guide.

Applications

This versatile 70mm PIR insulation board is suitable for a multitude of applications in both new build and refurbishment projects, helping to meet current UK Building Regulations and improve overall building performance:

• Wall Insulation: Ideal for external walls, partial fill cavity wall systems, solid masonry walls, and within timber or steel framed systems. It can also be used for internal wall lining upgrades.
• Roof Insulation: Perfect for pitched roofs (between and over rafters) and warm-deck flat roof constructions, preventing significant heat loss through the roof structure.
• Floor Insulation: Effective in solid concrete floors (above the DPM and below screed), suspended timber floors (between or above joists), and to enhance the performance of underfloor heating systems.
