What is Celotex pir insulation?

by Evan Johnson

Celotex pir insulation is a type of thermal insulation developed from polyurethane that can be used for roof, wall and floor applications. PIR is short for polyisocyanurate. It is an insulation material that provides us with one of the most thermally efficient available in the industry today. PIR foam is made by a chemical reaction that causes gases to be released and get trapped in cells within the board. That gas is less hot than air and makes it hard for heat to pass through.

This type of insulation can help you meet current and future Building Regulations. It also reduces the amount of carbon in the air. Celotex also manufactures Celotex Insulation GA4000 which has a low emissivity foil facing and is moisture resistant.

What is Celotex pir board?

Celotex pir board is an insulation board that is used to insulate buildings for energy conservation. Celotex pir boards are designed to cover all general needs for thermal insulation, fire resistance and sound reduction. Because of their versatility and high compressive strength, PIR celotex boards are often used in roofing jobs. The celotex boards are also ideal for underfloor applications, where insulation is needed below the floor.

Celotex insulation board is one of the most common types of high-quality PIR insulation and is used by both professionals and do-it-yourselfers.

What is Celotex made from? Celotex insulation boards are made of polyisocyanurate foam, aluminum foil and is one of the most thermally efficient products available. Celotex insulation boards are available in a range of thicknesses, ranging from 12mm to 200mm. Every Celotex product meets the required regulatory standards.

Celotex sizes

The typical length and width of a Celotex board is 2400mm by 1200mm, respectively. Celotex PIR boards come in multiple size options, including Celotex GA4000, Celotex TB4000 and Celotex XR4000. They offer a wide range of thicknesses to accommodate almost any insulation job. Celotex pir insulation is available in three different levels of thickness, each corresponding to a different size range.

  • Celotex TB4000

  • Celotex GA4000

  • Celotex XR4000

Celotex TB4000 are thinner insulation boards, ranging from 12mm to 40mm. The sizes of Celotex GA4000 range from 50mm thick to 100mm thick. The sizes of Celotex XR4000 pir insulation boards start at 110mm and go up to 200mm.
