Things to check before you order
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.
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.
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.
Delivery to Lowestoft: what helps
Boards are light but bulky; they travel in wrapped packs and should be stored flat and dry. Lowestoft is inside our standard mainland delivery area.
- In summer Lowestoft gets around 16h 50m of daylight, but early deliveries still beat the traffic and give the longest working day.
- On busy streets in Lowestoft, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
How much will you need?
Insulating 20 m² of rafters, floor or wall takes 8 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
Common questions from Lowestoft
How soon can PIR insulation boards be delivered in Lowestoft?
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 you deliver PIR insulation boards to a site with restricted access in Lowestoft?
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.
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.
