Where they are the same
Both are multilayer reflective quilts certified for pitched roofs, walls and floors. Each is certified with its own air-space arrangement — commonly around 25mm on each face, but the two certificates are not identical and the product's own document governs — both use a foil tape system, both are stocked by national merchants and both are fitted by the same installers. For most roofs the finished U-value with either, in the same build-up, is very close.
Where they differ
| SuperFOIL (SF19+) | SOPREMA SuperQuilt (previously YBS) | |
|---|---|---|

| Installer network | Formal approved installer scheme | Less formal; widely fitted |
| Availability | Wickes, Screwfix, Insulation Superstore, others | Widely stocked; long history |
| Price | Similar per m²; higher grades cost more | Similar per m² |
How to choose
- Get the target U-value for your roof from building control or your installer.
- Read each product's certificate for the build-up that reaches it.
- Pick whichever your installer has fitted most often. Familiarity with the tape and detailing beats a few points of thermal resistance.

Questions homeowners ask
Can I mix SuperFOIL and SuperQuilt on one roof?
You can, but use each product's own tape and keep to one certified build-up per roof so building control can check it.
