Getting the right PIR insulation boards
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.
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.
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.
Quantities: a worked example
Insulating 45 m² of rafters, floor or wall takes 17 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
Ordering PIR insulation boards for Gainsborough: FAQs
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 Gainsborough 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.
Is there a minimum order for delivery to Gainsborough?
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.
