Jul 17, 2012 · A Celotex corporate video showcasing the manufacturing and operational facilities as well as the added features and benefits of using Celotex insulation. Mar 21, 2017 · A low U-Value means better thermal performance and a high U-Value means worse resisting heat loss, whereas, single glazing has a high U-Value and loses heat rapidly. 3 A degree Kelvin is similar to a degree Centigrade but starting instead from -273.15C, the freezing point of IMPORTANT: On 1 September 2017, Celotex took the precautionary measure to temporarily suspend the supply of Celotex FR5000, Celotex CG5000, Celotex CF5000 and Celotex SL5000 while we investigate the results of recent tests (Parts 6 and 7 of British Standard 476). Materials relating to these products are for information only. PIR Insulation Specialists. Welcome to the Celotex Insulation Blog Here you will find the latest articles written by our insulation specialists focusing on product developments, building regulations and technical guidance notes.

50mm Celotex GA4050 is a multi-purpose insulation board that provides solution to overcome from the localized thermal bridges problem. Featuring a low emissivity foil facings, this board has been manufactured from tough polyisocyanurate (PIR) by using a perfect mix of certain blowing agents which acquires zero ozone depletion potential (zero ODP) and a low global warming impact (GWP).

Celotex U values U values measure how well a material performs as an insulator. The U value of a product varies widely depending on where the product is used, the materials around the Celotex insulation and more, for example the Celotex 50mm U value will vary according to the type of Celotex board being used, and where it is installed. U-values - Designing Buildings Wiki - Share your construction industry knowledge. U-values (sometimes referred to as heat transfer coefficients or thermal transmittances) are used to measure how effective elements of a building's fabric are as insulators. That is, how effective they are at preventing heat from transmitting between the inside and the outside of a building. Price of Celotex Insulation Boards Here at Insulation Superstore we are always looking to provide our customers with insulation products of the highest quality, at our famously competitive prices. Celotex is a market leader in the manufacturing of insulation boards, also known as PIR boards.

The Celotex Handy Guide is an essential tool that includes invaluable features such as easy-to-use ready reckoners, extensive U-value calculations, detailed illustrations and clear installation guidelines.

The XR4000 insulation board range from Celotex has been designed to provide users with a thinner insulation board that still achieves high U values. Celotex XR4000 boards have been developed to be used specifically in “cut-to-fit” applications, meaning that they can be fitted between rafters and joists to provide a highly insulating layer The Celotex U-value Calculator is one of the most comprehensive online calculators in the industry and is used by thousands of small to large architects and specifiers all over the country. So for this reason we have we have just made this bigger and better for our users to improve your experience. The unique Celotex online U-value calculator generates a U-value specific to the chosen construction and enables you to input a range of different construction parameters to evaluate their impact on thermal performance. The map and chart show each region of the U.S., the subsequent zones and corresponding R-values. R-value Insulation Chart Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic, walls, floors and crawlspaces.
