PIR insulation board

A PIR insulation board is a high-performance rigid insulation solution designed to deliver excellent thermal efficiency in a wide range of construction projects. Manufactured using polyisocyanurate (PIR) foam, these boards provide outstanding insulation performance while maintaining a slim profile, making them ideal for applications where space is limited. Suitable for roof insulation, wall insulation, and floor insulation, PIR boards help reduce heat loss, improve energy efficiency, and contribute to lower heating costs.

Benefits of PIR Insulation

• Excellent thermal performance with low thermal conductivity.
• Helps reduce heat loss and improve energy efficiency.
• Thin profile compared to many traditional insulation materials.
• Suitable for walls, floors, roofs and ceilings.
• Lightweight and easy to handle during installation.
• Can help reduce heating costs and carbon emissions.
• Moisture-resistant and durable for long-term performance.
• Supports compliance with UK Building Regulations.

Applications of PIR Insulation

PIR insulation is a versatile solution used in a wide range of residential and commercial construction projects, including:

• Pitched roof insulation
• Flat roof insulation
• Cavity wall insulation
• Internal wall insulation
• Floor insulation
• Loft conversions
• New-build developments
• Home renovation and extension projects

Its high thermal efficiency makes it ideal where maximum insulation performance is required within limited space.

Choosing the Right PIR Insulation

When selecting the appropriate PIR insulation for your project, consider factors such as thickness, application type (e.g., wall, floor, or roof), and thermal performance. Choosing the right PIR insulation board can make a significant difference in the overall efficiency and comfort of your building.

• Application: Make sure the PIR insulation product is designed for your specific application, whether it’s for roofs, walls, or floors.
• Thermal Requirements: Look for PIR insulation boards with higher R-values to meet your project’s thermal needs. High R-values ensure better insulation performance.
• Board Size: Consider the size and thickness of the insulation board you choose, ensuring it fits the dimensions and insulation requirements of your project
