Before your Johnstone delivery arrives

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

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• In summer Johnstone gets around 17h 35m of daylight, but early deliveries still beat the traffic and give the longest working day.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Getting the right 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.

Questions about PIR insulation boards delivery in Johnstone

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 there a minimum order for delivery to Johnstone?

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.

How soon can PIR insulation boards be delivered in Johnstone?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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.
