Things to check before you order
Thickness for the U-value
The thickness you need depends on the U-value the building regulations require and the rest of the build-up. Manufacturers publish U-value tables; your designer or building control will confirm.
Fire considerations
PIR is a combustible product. Building regulations restrict combustible materials in some situations, such as external walls of taller buildings; check what applies.
In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
Questions about PIR insulation boards delivery in Dorset
How many PIR boards do I need?
Divide the area by 2.88 m² (one 2400 × 1200 board) and add about 5 to 10 percent for cutting.
Do you deliver PIR insulation boards to Dorset?
Yes. We deliver across Dorset, including BH, DT. Our standard mainland delivery area covers Dorset. Send your list or call 0800 088 6341 and we will price it delivered to your postcode.
Is PIR better than mineral wool?
PIR insulates more per millimetre, so it suits tight spaces. Mineral wool is non-combustible, cheaper per square metre and better for sound.
Can you deliver PIR insulation boards to a site with restricted access in Dorset?
Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.
