Frequently Asked Questions

Is 50mm insulation enough?

With 50mm of insulation, you can provide a good level of thermal insulation for most applications. To be sure that 50mm is enough, you should calculate the U-value of the entire structure (not just the board in isolation). It is important to reduce cold spots and thermal bridging to get the best insulation value.

What's the U value of 50mm Celotex?

The U-value for a 2.4m x 1.2m sheet of celotex ga4050 50mm insulation is 0.022 W/m² K

How thick should Celotex be?

As a general rule, choose a general application insulation board that is as thick as you can afford and that space allows. Celotex is available in all sizes from 25mm up to 200mm

What is the difference between Celotex and polystyrene?

Celotex PIR insulation boards are more than just polystyrene. They are made from completely different materials. PIR offers far better insulating performance for the same thickness of board. They are manufactured using a blowing agent that has zero ozone depletion potential and low GWP (global warming potential) making it an eco friendly solution in construction.

Can Celotex be used for sound insulation?

Celotex insulation boards are primarily designed for thermal insulation purposes. However, they can provide a degree of sound insulation as well. For optimal sound insulation, you may want to consider using specialized acoustic insulation products or combining Celotex with other materials specifically designed for soundproofing.

How do I install Celotex GA4050 insulation boards?

To install Celotex GA4050 insulation boards, measure and cut the boards, attach them to the surface, stagger the joints, tape the joints, install a vapor control layer if needed, and finish the installation with the final surface layer. Always follow the manufacturer's guidelines and consult a professional if you are unsure about any aspect of the installation process.

What is the fire performance of Celotex insulation boards?

Celotex GA4050 insulation boards have a Euroclass E Reaction to Fire classification, according to BS EN 13501-1. This classification indicates that the boards have a low contribution to the spread of fire. However, it is crucial to follow local building regulations and fire safety requirements when using Celotex or any other insulation materials.

Can Celotex insulation boards be used for retrofit applications?

Yes, Celotex insulation boards can be used in retrofit applications to improve the thermal performance of existing buildings. Proper installation is critical to ensure optimal insulation performance and avoid potential issues such as thermal bridging or condensation.

Are Celotex insulation boards waterproof?

Celotex insulation boards are not waterproof but are designed to be moisture-resistant. However, prolonged exposure to water or moisture can affect the performance and integrity of the boards. In areas prone to water or moisture exposure, it is essential to provide adequate protection, such as a vapor control layer or waterproofing membrane, to maintain the performance of the insulation boards.

What is the environmental impact of Celotex insulation boards?

Celotex insulation boards are manufactured using a blowing agent with zero ozone depletion potential and low global warming potential (GWP), making them an environmentally friendly option for construction projects. Additionally, the improved thermal performance of Celotex insulation boards can help reduce energy consumption and greenhouse gas emissions associated with heating and cooling systems. The Celotex GA4050 insulation board has received an A+ rating in the BRE Green Guide, indicating a low environmental impact.
