25mm Celotex TB4025 PIR Insulation Board 2400x1200mm

25mm PIR insulation is suitable for pitched roofs, flat roofs, floors, masonry walls, timber-framed, and steel-framed systems, offering flexibility for both new build and refurbishment projects. The foil-faced construction helps maintain long-term thermal performance while reducing thermal bridging, making 25 mm Celotex an effective solution for improving the thermal efficiency of roofs, walls, and floors.

Where Can You Use 25mm Celotex PIR Insulation?

The 25mm Celotex PIR insulation board is suitable for a variety of building projects due to its flexibility and high thermal efficiency:

• Pitched Roof Insulation: Ideal for insulating between rafters, helping to reduce heat loss through the roof, which is often one of the main sources of energy inefficiency in buildings.
• Flat Roof Insulation: The board’s lightweight structure and easy installation make it suitable for insulating flat roofs in both residential and commercial settings.
• Floor Insulation: Use Celotex GA4025 beneath concrete or suspended floors to reduce heat loss and improve the energy efficiency of ground and upper floors.
• Masonry Walls: Excellent for solid or cavity wall applications, ensuring enhanced thermal performance and reducing thermal bridging.
• Timber and Steel Frame Insulation: The board can easily be fitted into timber-framed or steel-framed constructions, offering a high level of thermal protection.

What Should You Look for When Choosing a PIR Insulation Board for Your Project?

When selecting a PIR insulation board like the Celotex GA4025 for your project, there are several important factors to consider:

1. Thermal Conductivity (λ-Value): A lower thermal conductivity value means better insulation. The Celotex GA4025 has an impressive 0.022 W/mK, providing excellent thermal efficiency and helping you meet U-value requirements with less thickness.
2. Thickness and R-Value: Choose the board thickness based on the specific insulation requirements of your project. The 25mm thickness of Celotex GA4025 offers an R-value of 1.10 m²K/W, ensuring robust insulation performance.
3. Application Versatility: Consider the various applications of the insulation. The Celotex GA4025 can be used across multiple areas of a building, including floors, roofs, and walls, making it a highly flexible solution for different project types.
4. Ease of Installation: Look for insulation boards that are easy to handle, cut, and install. The lightweight design and low emissivity foil facings on both sides of Celotex GA4025 make it simple to fit into tight spaces, between rafters or joists.
5. Environmental Impact: PIR boards like the Celotex GA4025 offer excellent environmental credentials, including being CFC/HCFC free, having a low Global Warming Potential (GWP), and zero Ozone Depletion Potential (ODP). It’s also BRE Green Guide A+ rated, making it a sustainable choice for your project.
6. Compliance and Certifications: Ensure that the PIR insulation board meets local building regulations and standards. Celotex GA4025 is BBA-certified and meets BS EN 13165 standards, providing peace of mind in terms of quality and performance.

Additional Questions You May Have About PIR Insulation:

• How much insulation do I need for my project?
  

  The amount of insulation you need depends on the area you’re insulating and the required U-values. The Celotex GA4025 board comes in sheets measuring 2400mm x 1200mm, providing 2.88 m² of coverage per sheet, so you can easily calculate how many boards are required for your project.

• Is PIR insulation better than other types of insulation?

  PIR insulation, like Celotex GA4025, generally offers better thermal performance per thickness compared to other materials like EPS or mineral wool. It achieves higher thermal efficiency, meaning you can meet insulation targets with thinner boards, saving valuable space.

• What is the lifespan of PIR insulation?

  PIR insulation is known for its long-term performance and durability, providing consistent thermal efficiency over the lifespan of a building. Celotex GA4025 is manufactured to maintain its insulating properties for decades, ensuring reliable energy savings.
