25mm Celotex TB4025 PIR Insulation Board 2400mm x 1200mm

PIR, or polyisocyanurate, is a type of plastic. It's commonly used in insulation boards because of its excellent thermal performance, durability, and resistance to moisture. It's known for providing high insulation value with relatively minimal thickness.

Yes, the Celotex GA4000 is versatile and can be used for both internal and external insulation applications, including floors, walls, and roofs.

While the rigid structure of the GA4000 makes it relatively easy to install, it's always recommended to consult with or hire a professional for installation to ensure optimal performance and safety.

Yes, the GA4000 is manufactured with a low Global Warming Potential (GWP) and has zero Ozone Depletion Potential (ODP), making it an environmentally conscious choice.

PIR insulation boards like the GA4000 are known for their high thermal performance. They often provide better insulation value per unit thickness compared to many other common insulation materials.

Standard tools used for insulation, such as a sharp knife or saw for cutting and appropriate fixings for securing, should suffice. However, always refer to the manufacturer's guidelines or consult with a professional for best results.

With proper installation and maintenance, PIR insulation boards like the GA4000 can last for many years, often as long as the lifespan of the building itself.

While the GA4000 has some fire-resistant properties, it's not entirely fireproof. It's essential to combine it with other fire-resistant materials in areas where fire safety is a concern.
