Getting PIR insulation boards onto your Cwmbran site

Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Cwmbran 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.
• Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
• In summer Cwmbran gets around 16h 40m of daylight, but early deliveries still beat the traffic and give the longest working day.

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.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.

Your questions answered

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.

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.

Can I add other materials to my Cwmbran 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.

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

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.
