Before your Plymouth delivery arrives

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

• Give us the full postcode for the drop point; deliveries around PL2 are priced to the exact address.
• In summer Plymouth gets around 16h 26m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

How much will you need?

Insulating 16 m² of rafters, floor or wall takes 6 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

Before you order PIR insulation boards

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.

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.

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.

PIR Insulation Boards in Plymouth: questions

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 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 Plymouth?

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.

Can I add other materials to my Plymouth 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.
