Initial impressions : i was dubious of ordering after seeing some of the negative reviews, but equally amused by trade insulation replies....... i was looking at reviews because i'd never heard of the business, but after reading the reviews it became clear that actually the place was not a scam, the goods were arriving however people had not paid attention to tickboxes at checkout or were expecting craned deliveries (again not reading checkout\terms) and leaving their mrs at home to accept the orders i ordered 50mm celotex, and rwa45 insulation it's all arrived on the day they said it would yes i needed to help unload it, but guess what, i ordered it to use it so i fully intended to be handling it anyway and not only that even if i didn't need to help i would have had to move it anyway as they would have just done a kerbside delivery driver was great, he asked if i was comfortable in lifting the pallet of pir off in one go, (if you're not you're an adult, simply say no and open the pack) basically it came from travis perkins and i imagine it will come via other major suppliers too much like most of the online companies..... but because these guys order such large quantities they can pass on the discount and they're responsible for dealing with the the like of the tp if there's an issue summary : Yes i would recommend and yes i will order again

My materials were delivered within the specified delivery window. The delivery guy was very skilled at navigating our driveway and he dropped the materials right at our front door. I’m delighted with the quality of materials and service and I will reorder from Trade Insulations Ltd at the next stage of my renovation.

  17. 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

  18. 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.

  19. 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

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.
