2400mm x 1200mm 8ft x 4 ft. PIR/PF Foil/ Standard Face Boards

PIR & PF Foil/Standard Faced Insulation Boards 2400mm x 1200mm (8ft x 4ft)

Upgrade your thermal efficiency with our 2400mm x 1200mm PIR insulation boards and PF insulation boards, available in PIR Foil, PIR Standard Face, PF Foil, and PF Standard Face with different thicknesses. These rigid boards deliver exceptional thermal efficiency, energy savings, and flexible installation options.

Whether you need foil-faced boards for added vapour control or standard face boards for use with a separate vapour barrier, we have the perfect insulation solution for your project.

PIR Foil Boards: Our PIR Foil insulation boards combine rigid PIR foam with a foil facing to provide excellent thermal efficiency and integrated vapour control. Ideal for airtight building designs. To know more about PIR Foil insulation boards click here.

PIR Standard Face Boards: PIR Standard Face boards offer the same high-performance insulation as foil boards but without the foil facing, allowing greater flexibility in finishing or the addition of a separate vapour membrane. To know more about PIR Standard Face boards click here.

PF Foil Boards: PF Foil insulation boards feature rigid PF foam with a foil facing for enhanced thermal efficiency and vapour control. Ideal for energy-efficient builds, these boards are commonly used in projects where a reflective vapour layer is required. To know more about PF Foil insulation click here.

PF Standard Faced Boards: PF Standard Faced boards provide the same durability and insulation performance without the foil facing, giving you flexibility to pair with your own vapour barrier or finishing system.

Why Choose Our PIR & PF Insulation Boards?

FAQ

1. What is a PIR insulation board?
A PIR (Polyisocyanurate) insulation board is a rigid, high-efficiency thermal insulation board designed to reduce heat loss and improve energy efficiency in buildings. Its closed-cell foam core provides excellent thermal insulation while remaining lightweight and easy to install. PIR boards are commonly used for both new builds and renovation projects, making them a popular choice where high insulation performance is needed with minimal thickness.

2. What is the difference between PIR and PF insulation?
PIR (Polyisocyanurate) and PF (Phenolic Foam) insulation are both high-performance rigid insulation materials, but PF insulation generally offers slightly better thermal performance, allowing the same insulation value to be achieved with a thinner board. PIR insulation is typically more cost-effective, easier to source, and widely used for various projects while PF insulation is often chosen for projects where space is limited and maximum thermal efficiency is required. The best choice depends on your project’s insulation requirements, budget, and available space.

3. What is the difference between foil-faced and standard-faced PIR boards?
Foil-faced PIR boards are covered with aluminium foil on both sides, which helps improve moisture resistance and can enhance thermal efficiency when installed with an appropriate air gap. Standard-faced PIR boards have a different facing material, such as coated paper or composite facings, and are commonly used where foil facings are not required. The right choice depends on your application, installation method and the manufacturer’s recommendations.

4. How do you cut PIR insulation?
PIR insulation boards can be cut using a fine-toothed hand saw, insulation saw, or a sharp utility knife for thinner boards. Measure and mark the cutting line accurately, then cut on a stable surface to achieve a clean, straight edge. Always wear appropriate safety equipment, including gloves, eye protection, and a dust mask, and follow the manufacturer’s cutting and installation recommendations.
