Delivering PIR insulation boards in Alfreton

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.

Estimating your PIR insulation boards

Insulating 30 m² of rafters, floor or wall takes 12 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

Things to check before you order

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.

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.

PIR Insulation Boards questions

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.

Is there a minimum order for delivery to Alfreton?

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.

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

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

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.
