What is the U value of Celotex?
0.2 W/m2k .
Using Celotex to fill the cavities is more expensive, but you will only need to use 100mm celotex to achieve a U-value of 0.2 W/m2k .
Can Celotex be used below ground?
While Celotex PIR boards have a good compressive strength, they cannot be laid below a raft slab and take the structural load of the building. They can, however, be installed above the raft slab, in the same arrangement as described above.
What Celotex thickness should I use for garage conversion?
3 Answers from MyBuilder Conversion Specialists We also use 100mm celotex in the floor and building control have always been happy. They will want either 1m deep footings or big lintels for your bricking up. You can dot and dab those internal walls as you say.
What thickness of Celotex do I need?
Take into consideration the thickness you want to insulate to and if there is any pre-existing insulation in place, we recommend using 300mm if using wool insulation and 150mm if using the rigid insulating boards like Celotex or Kingspan.
How do you find the U-value?
It is measured in units of W/m2. K (Watts per metre squared Kelvin). It is a way of measuring the insulating properties of the building element. The lower the U-value, the better insulated the building element is.
What is the U-value of a concrete floor?
For basement floors the U-value should also not exceed 0.25 W/m2K and for basement walls it is 0.25 W/m 2K for domestic/0.30 W/m2K for non-domestic. For upper exposed floors and for floors over unheated spaces the reader is referred to Part 6.
Is Celotex waterproof?
Is Celotex Waterproof? Yes, Celotex insulation is designed to effectively fight excess moisture in the air. This is thanks to the closed cell structure of their products, which makes them hydrophobic; meaning they do not absorb water.
What insulation do I need for concrete floor?
EPS is a good choice for insulating a concrete floor because it has a long term R-value, alongside a consistent level of thermal resistance, and it is produced in easy to manage sheets to allow easy installation.
How can I insulate my garage cheaply?
Fiberglass roll insulation is the cheapest and easiest type to install, provided that your garage’s interior walls have not been constructed. Unroll the insulation between the wall studs with the vapor barrier facing the inside of the garage.
What is the U value of 50mm Celotex?
