Uninsulated or poorly insulated lofts are responsible for roughly 25% of a home’s total heat loss. Modern multifoil solutions—specifically SuperFOIL—offer an exceptionally high-performance option for homeowners looking to drastically lower energy bills without sacrificing headroom or loft storage.

Unlike traditional mineral wool that relies purely on bulk to trap warm air, SuperFOIL uses multi-layered, highly polished reflective foil interspersed with thermal wadding. Reflective Heat Shield: In winter, SuperFOIL bounces up to 95–97% of radiant heat back into your living spaces. In summer, it reverses this effect to reflect external solar heat away, keeping upper floors comfortably cool year-round.

Ultra-Slim Profile: Traditional fibreglass requires a bulky 270mm depth to meet modern standards. SuperFOIL achieves equivalent or superior thermal performance in a fraction of the thickness, leaving timber rafters visible and preserving usable loft floor space.

Integrated Vapour Control: The solid foil layers form a continuous vapour barrier that prevents warm, moist air from escaping into cold roof spaces. This eliminates timber rot, dampness, and structural condensation risks.

Creating Sealed Air Gaps: SuperFOIL relies on small, counter-battened air gaps on either side of the foil to maximize radiant heat reflection. Without these exact air spaces, heat transfers via conduction and thermal efficiency drops significantly.

Maintaining Roof Ventilation: While the living envelope is sealed tight, the cold side of the roof structure still needs adequate cross-ventilation to keep rafters healthy and preserve structural integrity. Immediate Bill Reductions: Cuts loft heat loss, noticeably lowering daily boiler runtime and heat pump electricity consumption.

Clean & Non-Hazardous: Fiber-free material means no irritating dust, skin itching, or dangerous particle inhalation during or after installation.
