Order with allowance
Use the calculator estimate so you avoid under-ordering mid-install.
Which roll width should I choose?
Choose the width that best matches the space you are insulating. 370mm is better for narrower or awkward runs; 570mm is better for faster coverage across wider open areas.
How much extra should I allow?
Around 10% extra is a sensible starting point for cuts, joins and awkward loft areas. Complex spaces may need more.
Can I use this outside lofts?
Yes, it can be used for suitable walls, floors, camper vans, motorhomes and acoustic projects. Always check the requirements of your specific build.
Can you supply custom insulation sizes?
Yes. If our standard 370mm or 570mm rolls are not suitable, contact us with your measurements and project details. We can advise on bespoke sizes and fitting options.
Will the roll expand after opening?
The rolls are compressed for easier delivery and storage. After opening, allow the material time to recover towards its stated thickness before fitting.
