GA4000 Celotex 100mm
When buying 100mm insulation boards online, we advise you know exactly what you need before placing the order to prevent any potential delays to your project. To know how many 100mm Celotex boards you need for your project, you will have to work out the area required. You can do this by simply multiplying the height by the width of the area you want to apply insulation. For example if the space was 3m by 3m then the total area would be 9m. Each 100mm Celotex has a coverage of 2.88m2, which means you would order a minimum or 4 boards to cover this area in the given example. We advise ordering slightly over to account for wastage.
If you are unsure of the thickness required, we always advise speaking to a building professional or architect. Furthermore, our most popular size is the 100mm Celotex board and is a general purpose board. This means it can be used in walls, roofs and floor applications.
If you are looking for cheap Celotex 100mm and a first class service, order today at Trade Insulations.

118 reviews for Celotex 100mm PIR Insulation Board – GA4100 (2400mm x 1200mm x 100mm) 2.88m2
Question: | How do you cut Celotex 100mm Insulation Board? |
max |
Answer: | Celotex 100mm boards can be easily cut like any other PIR board. The best and most efficient way is to use a handsaw. Measure precisely what you need and mark it with a pencil on the board. Once you have marked it, use the handsaw to make the cut. This should produce minimal dust, however, ensure PPE is worn to prevent debris inhalation. | |
Question: | What is the U Value of 100mm Celotex? |
tradein |
Answer: | We are unable to calculate the U-Value as this would depend on the application. For the most accuracy, this question should be presented to your builder or architect. | |
Question: | What is the best way to store this product? |
tradein |
Answer: | Celotex PIR insulation boards are best stored in cool and dry conditions. Avoid exposing the insulation board to bad weather and take extra care when handling the board to avoid damage to the corners due to knocks and bumps. | |
Question: | Are these Celotex boards second hand? |
tradein |
Answer: | Absolutely not. Our insulation boards are brand new despite our low price. We believe in providing top brands at trade prices. | |
Question: | Can I use 100mm Celotex Board on floors? |
tradein |
Answer: | Yes. The GA4100 Celotex Board is a multi-purpose board. This means it is suitable for roof, wall and floor applications. | |
Question: | Is this product different to GA4000? |
tradein |
Answer: | The product code for Celotex 100mm is GA4100. GA4000 is a range of PIR boards by Celotex with thicknesses between 50mm and 100mm. Celotex GA4100 is included in the GA4000 range. | |
