PIR Insulation Boards: choosing well
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.
Planning the drop in Harrow
Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Harrow is inside our standard mainland delivery area.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
Sizing your order
Insulating 45 m² of rafters, floor or wall takes 17 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
