Before your Daventry delivery arrives

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

• In summer Daventry gets around 16h 47m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• If neighbours share the access, it helps to let them know a lorry is coming.

Choosing 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.

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.

Your questions answered

Is there a minimum order for delivery to Daventry?

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.

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.

How soon can PIR insulation boards be delivered in Daventry?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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.
