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.

Quantities: a worked example

Insulating 12 m² of rafters, floor or wall takes 5 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

Planning the drop in Southampton

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

• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

Your questions answered

Can I add other materials to my Southampton delivery?

Yes. Put everything on one list, from PIR insulation boards to fixings and PPE, and we will price it as one delivery where the products can travel together.

Do you deliver PIR insulation boards to trades and homeowners in Southampton?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

What is the foil for?

The foil facing reflects heat, protects the foam and, when joints are taped, can act as a vapour control layer.

Can PIR be used in external walls?

In some situations, but building regulations restrict combustible insulation in external walls of certain buildings. Check the rules for your building.
