Celotex GA4000 is a high-performing PIR board from Saint-Gobain with a low K-Value of 0.022 W/mK. The low thermal conductivity of the PIR insulation ensures superior thermal insulation and significant saving all year round. They also decrease thermal bridging in all applications. These products provide simple solutions to overcome thermal bridges in specific situations.
Celotex PIR is a muti-purpose board suitable for use across projects. Celotex boards can be used for wall insulation, floor insulation, and roof insulation thanks to their strong and thermally efficient PIR core. They are also approved for use in cavity wall insulation. Celotex PIR is also dimensionally stable. Their performance does not decrease with time and rigid foam board does not say overtime and its thermal performance remains unchanged with time. They provide reliable and long term solutions.
With low emissivity foil facings on both sides, the PIR insulation reflects heat and prevents heat loss through radiation. Foil facings also serve as a vapour barrier, protecting foam board and your walls from moisture.

To help you understand the product in a bit more in detail, we have put together a product guide for Celotex GA4000, just for you:
What is Celotex GA4000?
Celotex GA4000 is a multi-purpose PIR insulation board. Made with superior-quality polyisocyanurate or polyiso, this insulation board gives the highest possible thermal insulation in every application.
Dimensions and Coverage of Celotex GA4000
Celotex GA4000 PIR insulation boards are about 2400mm long and 1200mm wide. They come in varying thicknesses from 50mm to 100mm. Each PIR board covers about 2.88sq.m
Benefits of Celotex GA4000
Celotex GA4000 insulation has factory-faced foil facings on both sides that reflect radiant heat to the source. This way, Celotex GA4000 not only reduces heat loss by conduction but a little heat loss through radiation is restricted as well. Foil-facings in this PIR insulation also act as a moisture barrier, preventing the insulation and its application against water ingress.
Like most PIR insulation boards, Celotex GA4000 also have a low thermal conductivity of 0.022 W/mK that ensures superior insulation. But, it is their versatility and ease of use, that makes them unique.
Celotex GA4000 is BBA-approved, which makes them perfect to insulate cavity walls. Additionally, they are also ideal for insulating walls, roofs and floors.
Celotex GA4000 helps you achieve the desired U-value easily. They comply with the required building regulation.
Uses of Celotex GA400
Celotex GA4000 is versatile in application. These multi-purpose PIR boards can be used for:
Roof Insulation: Pitched roof and flat roof
Wall Insulation: Cavity walls, internal and external
Floor Insulation: Solid floor, suspended floors
Is Celotex GA4000 environment-friendly?
Celotex GA4000 is made using sustainably sourced materials. It has an A rating from BRE Green Guide.
What is the difference between Celotex TB4000 and Celotex GA4000?
Both Celotex GA4000 and TB4000 are made with the same material by the same manufacturer. The only difference lies in their thickness. While Celotex GA4000 comes in a thickness range of 50mm to 100mm, Celotex TB4000 is thinner and is available in thicknesses ranging from 25mm to 40mm.
Similarly, Celotex XR4000 is slightly thickener compared to Celotex GA4000, as they are made in thickness ranging from 110mm- 200mm.
Is Celotex GA4000 Fireproof?
Celotex Ga4000 is not fireproof insulation. They achieve a Euroclass E rating for reaction to fire, and hence cannot be considered fire-resistant or fireproof insulation.
Is Celotex GA4000 hazardous?
Celotex GA4000 is not considered to be hazardous. It does not harm you or your health in any way. However, care must be taken to use appropriate personnel protection equipment, like gloves, masks etc, while installing Celotex PIR insulation boards.
Is Celotex GA4000 better than Kingspan?
Celotex and Kingspan are big brands in the insulation industry and have been around for more than 50 years. Celotex GA4000 or Celotex PIR boards in general and Kingspan PIR insulation are made of the same material polyiso or polyisocyanurate.
While there may be tiny differences in the final product between these two manufacturers of PIR insulation, the choice between Celotex and Kingspan always boils down to their application, plus your preference and budget.
