Choosing PIR insulation boards

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.

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.

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.

Delivering PIR insulation boards in Borehamwood

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

• If neighbours share the access, it helps to let them know a lorry is coming.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• Deliveries are to the kerb, drive or within crane reach; ask if materials need to go further.

Questions about PIR insulation boards delivery in Borehamwood

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 there a minimum order for delivery to Borehamwood?

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.

Can I add other materials to my Borehamwood delivery?

Yes. Put everything on one list, from PIR insulation boards to fixings and PPE, and we will price it as one delivery where the products can travel together.

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.
