Description
Description
Celotex PIR Insulation Boards are versatile polyisocyanurate (PIR) solutions designed for easy installation across floors, walls, and roofs. They come in a standard size of 2400mm x 1200mm, with thicknesses ranging from 20mm to 200mm to suit various applications. Commonly chosen thicknesses include:
- 100mm – Ideal for high-performance insulation in roofs and walls.
- 50mm – Suitable for floors and walls where space is limited but good thermal efficiency is needed.
- 25mm – Great for areas requiring thinner insulation, especially floors.
What's the difference between Celotex TB4000, GA4000, and XR4000?
While they are all the same type of board, they are classified as TB4000, GA4000, or XR4000 according to their thickness: TB4000 for thinner boards, GA4000 for medium thickness, and XR4000 for thicker options. See a breakdown below:
- Celotex TB4000 is available in thinner sizes, from 12 mm to 40 mm. It’s designed to reduce thermal bridging (when heat escapes through parts of a structure with less insulation). It’s often used around the edges of floors, walls, or pitched roofs to boost thermal efficiency without adding much bulk.
- Celotex GA4000 is a General-purpose PIR insulation board suitable for pitched roofs, walls, dry lining, and floor insulation. Its thickness ranges from 50mm to 100mm, and is known for its versatility and high thermal performance. It can be used effectively in various building applications, including being installed in the middle of pitched roofs.
- Celotex XR4000 is a high-performance PIR insulation board suitable for various applications, including walls, roofs, and floors. It’s offered in a range of thicknesses, from 110mm - 200mm. XR4000 is particularly effective in reducing heat loss in external applications and is often used where high insulation values are required.
