Choosing PIR insulation boards

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.

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.

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.

Delivery to Carshalton: what helps

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Carshalton is inside our standard mainland delivery area.

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Give us the full postcode for the drop point; deliveries around SM5 are priced to the exact address.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

A quick quantity check

Insulating 30 m² of rafters, floor or wall takes 12 boards of 2400 × 1200 mm including offcuts. The thickness depends on the U-value you need, so check it before you order. Try the insulation calculator

Ordering PIR insulation boards for Carshalton: FAQs

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.

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.

Is there a minimum order for delivery to Carshalton?

There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.

Can you deliver PIR insulation boards to a site with restricted access in Carshalton?

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.
