PIR Insulation Boards: choosing well

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 Chesterfield

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

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

A quick quantity check

What is the foil for?

The foil facing reflects heat, protects the foam and, when joints are taped, can act as a vapour control layer.
