Planning the drop in Redhill

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

• 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.
• If the site is up a shared drive or behind other houses, tell us the distance from the road.

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.

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.

Common questions from Redhill

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

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

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 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 Redhill?

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.
