How delivery works in Yeovil

• On busy streets in Yeovil, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• If neighbours share the access, it helps to let them know a lorry is coming.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

Before you order PIR insulation boards

Sealing joints

Tape the joints with foil tape so the foil layer works as a continuous vapour control layer where the design relies on it.

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.

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.

Your questions answered

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 Yeovil?

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.

Do you deliver PIR insulation boards to Yeovil?

Yes. We deliver across Yeovil, including BA20, BA22, BA21. Yeovil is inside our standard mainland delivery area. Send your list or call 0800 088 6341 and we will price it delivered to your postcode.

How thick should PIR insulation be?

It depends on where it goes and the U-value required. Pitched roofs often need 100 mm or more between and under rafters; floors and walls vary. Use the maker's U-value tables or ask your designer.
