Question:

What's the best way to cut 150mm thick celotex board?

insulationadmin
08-Feb-2023

Answer:

As mentioned previously across all thicknesses of Celotex PIR. The easiest and most cost effective way to cut a PIR board is to use an off the shelf hand saw. There are many guides on the product pages to help.

Question:

Can I use 150mm loft roll instead of 150mm Celotex?

insulationadmin
08-Feb-2023

Answer:

Short answer would be no! they are worlds apart when it comes to thermal values, in fact a 150mm board is twice as good thermally than loft roll.

Question:

I ordered 150mm Celotex but it should of been 75mm, can we cut the boards long ways so that I can get 2 75mm celotex boards from every 1 of the 150mm?

insulationadmin
08-Feb-2023

Answer:

No, you cannot do this. This would effect the thermal conductivity of the board and would actually be useless afterwards. Both sides of the board needs to have the foil face as when it was originally manufactured.
