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.

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.

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.

Estimating your PIR insulation boards

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

Getting PIR insulation boards onto your Sunbury-on-Thames site

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• 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.

Your questions answered

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.

Is there a minimum order for delivery to Sunbury-on-Thames?

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.

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 I add other materials to my Sunbury-on-Thames 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.
