15 reviews for 50mm Celotex Insulation Board – GA4050 (2400mm x 1200mm x 50mm) 2.88m2

  1. William

    ordered some 50mm celotex, easy to cut and easy to install, not bad for my first bit of DIY

  2. Lucy

    Used 2 sheets of 50mm instead of 100mm. Worked really well.

  3. Peter L

    I have stopped comparing prices because it is a waste of my time. You guys always come out on top and the service is bang on.

  4. Fred Douglass

    Doubled up on 50mm instead of using 100mm, took bit longer but worked great.

  5. Mrs Stokes

    ordered 60 sheets of 50mm Celotex, got delivered today – thanks to Derek for the speedy delivery.

  6. Steve Borg

    ordered 10 sheets of 50mm Celotex Insulation Board, asked my son and his friend to help me move them, felt a bit silly as only about 6kg each (VERY LIGHT)

  7. Brad

    Was let down by another company but had zero issues with Trade Insulations. They didn’t faff about and got me booked in as a priority. Will use again

  8. Andy S

    Very good website and easy to use. Our Celotex came quickly and we even got a call to follow up on how the experience was. It felt like Trade Insulations are actually a company who will look after you.

  9. Trevor

    I was pleasantly surprised to see your 50mm Celotex boards were brand new. At the prices you sell at, I thought they would have been seconds. Can’t fault your company at all. Won’t be using the builders merchants again

  10. Dave F

    Price of this has shot up but it looks like everyone has increased the price of this

  11. Arthur Wilson

    Delivery arrived within 2 days, very pleased!

Question:

How much does a 50mm Celotex board weigh?

insulationadmin
08-Feb-2023

Answer:

It weighs approximately 5.53kg. Very lightweight compared to other Insulation materials.

Question:

What do you use to cut the Celotex board?

insulationadmin
08-Feb-2023

Answer:

We honestly think the easiest way to cut Celotex PIR Insualtion boards is with a standard off the shelf handsaw. Most people have one in their shed so no need to go out and buy an expensive saw!

Question:

Is 50mm Celotex PIR as good as 50mm Kingspan PIR?

insulationadmin
08-Feb-2023

Answer:

Yes. Celotex has a thermal conductivity of 0.022 W/mk and Kingspan PIR also has a thermal conductivity of 0.022W/mk. PIR Insualtion generally has the same thermal values. Its always best to check with your architect and builder.

Question:

What should I do if I leave my celotex out in the rain?

insulationadmin
08-Feb-2023

Answer:

Don't panic too much, as long as you can cover it up after and let it dry in your garage or over time covered up. Just do not install your Celotex if it's wet as it will take quite a long time for the product to dry out.

Question:

Do you sell 50mm Celotex in half sheets?

insulationadmin
08-Feb-2023

Answer:

Unfortunately we do not. As mentioned above previously, using a hand saw to cut them to size is very easy. So no problem the required size of board you can cut them to suit.
