PIR Insulation Boards: choosing well

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 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.

Getting PIR insulation boards onto your Berkhamsted site

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

• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

PIR Insulation Boards in Berkhamsted: questions

Can you deliver PIR insulation boards to a site with restricted access in Berkhamsted?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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

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.

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.
