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.

Getting PIR insulation boards onto your Portsmouth site

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.
• Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.

How much will you need?

Insulating 30 m² of rafters, floor or wall takes 12 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

Ordering PIR insulation boards for Portsmouth: FAQs

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.

Is there a minimum order for delivery to Portsmouth?

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.

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

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

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.
