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.

Thickness for the U-value

The thickness you need depends on the U-value the building regulations require and the rest of the build-up. Manufacturers publish U-value tables; your designer or building control will confirm.

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.

Sizing your order

Insulating 12 m² of rafters, floor or wall takes 5 boards of 2400 × 1200 mm including offcuts. The thickness depends on the U-value you need, so check it before you order. Try the insulation calculator

Getting PIR insulation boards onto your Carmarthen site

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

• On busy streets in Carmarthen, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• With roughly 7h 46m of daylight in Carmarthen around the shortest day, morning deliveries leave more working light for the job.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.

Your questions answered

Is there a minimum order for delivery to Carmarthen?

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.

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.

Can I add other materials to my Carmarthen 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 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.
