Things to check before you order

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 Windsor site

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

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Sizing your order

Insulating 36 m² of rafters, floor or wall takes 14 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

Questions about PIR insulation boards delivery in Windsor

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

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.

Can I add other materials to my Windsor 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.

How thick should PIR insulation be?

It depends on where it goes and the U-value required. Pitched roofs often need 100 mm or more between and under rafters; floors and walls vary. Use the maker's U-value tables or ask your designer.
