Picking the right product

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.

How much will you need?

Insulating 30 m² of rafters, floor or wall takes 12 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

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• On busy streets in Hertford, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Common questions from Hertford

How soon can PIR insulation boards be delivered in Hertford?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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 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.

Is there a minimum order for delivery to Hertford?

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.
