Before your Feltham delivery arrives

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

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Quantities: a worked example

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

Choosing 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.

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.

Your questions answered

How many PIR boards do I need?

Divide the area by 2.88 m² (one 2400 × 1200 board) and add about 5 to 10 percent for cutting.

Can I add other materials to my Feltham 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.

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.

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

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