Pitched Roof (Between Rafters)
- Multifoil blanket (19-layer), taped & sealed
- Counter-batten/service void
- Plasterboard finish
- Notes: manage ventilation and vapour control per roof design.
Warm Roof Hybrid (Above Deck + Between Rafters)
- PIR above deck (thickness to target)
- Multifoil beneath rafters, sealed
- Service void + plasterboard
- Notes: popular where tighter U-values are required with minimal internal loss.
Stud Wall (Internal)
- Multifoil to studs, taped
- Service battens
- Board finish
- Notes: check services routing and vapour control strategy.
Not sure? We'll recommend multifoil-only or hybrid specs to hit your target with the least disruption.
Multifoil vs PIR: Quick Comparison
| Factor | SuperQuilt Multifoil | PIR Board |
|---|---|---|
| Install Speed | Fast — rolls unroll and cut cleanly | Slower — rigid boards need careful cutting |
| Thickness | ~40 mm relaxed | Varies, often 50–200 mm |
| Thermal Bridging | Reflective layers reduce bridging at fixings | Bridging at joints and fixings without careful detailing |
| Best use cases | Tight rafters, loft conversions, retrofit | Flat roofs, above-deck warm roofs, high U-value targets |
| Hybrid options | Pairs well with PIR for tighter targets | Can be used alone or with multifoil |

FAQs
Will multifoil pass Building Control?
Yes—when correctly specified and installed with the right build-up and documentation. We provide project-specific details and link to manufacturer certificates used by Building Control.
Do I still need ventilation or a vapour control layer?
It depends on your roof/wall design. We'll advise on ventilation gaps, airtightness and vapour control to manage condensation risk.
What thickness is the blanket?
Typical 19-layer multifoil is around 40 mm (relaxed). Performance comes from multiple reflective layers working together, not just bulk thickness.
Can I combine multifoil with PIR?
Absolutely. Hybrid build-ups (multifoil + PIR) are common where tighter targets are required with minimal internal loss.
Is it suitable for floors and outbuildings?
Yes—multifoil is widely used in suspended floors and garden rooms/garages. We'll specify the right layering and accessories.
How quickly can you start?
Surveys are often available within a week. Start dates depend on project size and access—tell us your timeline and we'll work to it.
What documentation do I receive?
Data sheets, install guide, a project-specific build-up and U-value summary, plus certificate links for Building Control.
Do you sell to trade?
Yes—installers get trade pricing, cut lists, accessory packs and direct technical support. [Open a Trade Account]
