Introduction to Insulation Boards
Insulation boards are essential for improving energy efficiency, thermal performance, and soundproofing in buildings. Available in various materials and thicknesses—from 6mm to 150mm—they are used in walls, roofs, floors, and specialized applications like coolrooms.
This guide covers the best insulation board types, their thickness options, and ideal applications to help you choose the right product for your project.

2. Medium-Thickness Boards (30mm – 75mm)
- 30mm, 40mm, 50mm, 60mm, 70mm, 75mm
- Best for:
- External wall insulation (EWI)
- Roof and loft insulation
- Commercial and residential thermal upgrades

3. Thick Insulation Boards (90mm – 150mm)
- 90mm, 100mm, 120mm, 150mm
- Used in:
- High-performance thermal insulation
- Floor insulation (especially 100mm floor insulation boards)
- Cold storage & coolroom panels (e.g., 50mm coolroom panels)

Types of Insulation Boards
1. PIR Insulation Boards
- High thermal efficiency (best R-value per thickness)
- Common sizes: 25mm, 50mm, 100mm PIR insulation boards
- Used in roofs, walls, and floors
2. Rockwool Slabs
- Fire-resistant & soundproof
- Example: 50mm Rockwool slabs
3. Sandwich Panels
- Pre-insulated panels for quick installation
- Sizes: 40mm, 50mm, 75mm insulated roof panels
4. Coolroom & Refrigeration Panels
- Designed for temperature-controlled environments
- Example: 25mm & 50mm coolroom panels
How to Choose the Right Insulation Board?
- For walls: 50mm – 100mm PIR or rigid foam boards
- For roofs: 70mm – 150mm insulated roof panels
- For floors: 100mm floor insulation boards
