Getting PIR insulation boards onto your Dumbarton site

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

• If the site is up a shared drive or behind other houses, tell us the distance from the road.
• Give us the full postcode for the drop point; deliveries around G82 are priced to the exact address.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.

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 Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.

How much will you need?

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

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 Dumbarton 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.

Is there a minimum order for delivery to Dumbarton?

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.
