110mm PIR Insulation Board 2400mm x 1200mm ( 8″ x 4″ )

Achieve exceptional thermal performance and energy efficiency with our 110mm PIR Insulation Board. Measuring 2400mm x 1200mm (approximately 8ft x 4ft), this high-quality polyisocyanurate (PIR) insulation board is engineered to provide outstanding insulation across a wide range of construction applications, from pitched roofs to solid floors and timber frame walls. Its rigid, lightweight design and low thermal conductivity make it an essential component for modern, energy-conscious building projects in the UK.

Key Features and Specifications

• Material: Rigid polyisocyanurate (PIR) foam core
• Facings: Low emissivity composite foil on both sides for enhanced thermal performance and vapour resistance
• Dimensions: 2400mm (Length) x 1200mm (Width) x 110mm (Thickness)
• Board Coverage: 2.88m² per board
• Thermal Conductivity (Lambda λ): 0.022 W/mK, ensuring excellent thermal efficiency
• Compressive Strength: Typically >120 kPa, offering robust performance under load
• Fire Classification: Euroclass E or F (Class 1 surface spread of flame)
• Benefits: Lightweight, easy to cut and install, contributes to significant energy savings, zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP)

Applications

This versatile 110mm PIR insulation board is suitable for a multitude of applications in both new build and refurbishment projects. It is widely used for insulating pitched roofs (between, over, or below rafters), warm flat roofs, and solid or suspended timber floors, including those with underfloor heating systems. The boards are also ideal for cavity wall insulation (partial fill), timber frame walls, steel frame systems, and internal wall lining, helping to minimise heat loss and reduce thermal bridging throughout the building envelope.

Delivery in and Around London

We offer reliable and efficient delivery of our 110mm PIR Insulation Boards across London and the South East. Our delivery service covers all London boroughs, including Croydon, Lewisham, Southwark, Camden, and Hackney, as well as the wider Greater London area, encompassing Enfield, Bexley, Redbridge, and Barnet. We also serve surrounding counties such as Kent, Essex, Surrey, and Hertfordshire.
