Picking the right product

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.

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.

Planning the drop in March

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. March 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.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• On busy streets in March, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
