Picking the right product

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.

• Give us the full postcode for the drop point; deliveries around BS16 are priced to the exact address.

• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

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 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.

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

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

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

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.
