Planning the drop in Darlington

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

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Give us the full postcode for the drop point; deliveries around DL3 are priced to the exact address.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Getting the right 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.
