Delivery to Ampthill: what helps

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

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

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.

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.
