SuperFOIL SF60 Multifoil Insulation – Maximum Performance 3-in-1 Solution SuperFOIL SF60 is the highest-performance product in the SuperFOIL multifoil insulation range, designed for projects where maximum thermal performance is required while still maintaining a slim and efficient build-up. With a nominal thickness of 100 mm, SF60 delivers exceptional insulation performance combined with a radiant barrier and an integrated vapour control layer (VCL) in one advanced system. It is suitable for roofs, walls, and floors, making it ideal for new builds, retrofits, timber-frame construction, and professional building applications where demanding U-value targets must be achieved. This is a vapour-closed multifoil insulation with an integrated vapour control layer (VCL), designed for internal applications where airtightness and condensation control are required. Comparable performance ratios for SuperFOIL insulation products vary according to product thickness and construction build-up. For thicker systems, such as SF60, equivalent thermal performance varies depending on installation method, air gaps, and overall system design and must be assessed using the official SuperFOIL U-Value Calculator for the specific application. As a reference within the SuperFOIL range, internal comparative assessments indicate that 65 mm of SuperFOIL SF40 can achieve thermal performance comparable to up to 450 mm of traditional mineral wool insulation (λ = 0.040 W/mK) under typical installation conditions.These values are provided for indicative comparison purposes only. Final thermal performance must always be verified using the official SuperFOIL U-Value calculation for the specific construction build-up, supported by the certified R-Values of each product. Product Dimensions & Coverage Thickness: 100 mm Length: 8 m Width: 1.5 m Coverage: 12 m² per roll Weight: approx. 17.75 kg 3-in-1 Multifunctional Design SuperFOIL SF60 combines three essential functions in a single product: High-performance thermal insulation Radiant barrier that reflects radiant heat back into the building in winter and reduces solar heat gain in summer Integrated vapour control layer (VCL), removing the need for a separate vapour barrier This integrated design reduces system complexity, minimises material layers, and supports efficient compliance with modern building regulations. Thermal Performance SF60 works across all three modes of heat transfer — conduction, convection, and radiation — unlike traditional insulation materials that primarily address conduction alone. Certified thermal performance (core value + air spaces, EN 16012): Core R-Value: 3.58 m²K/W Roof (incl. air spaces): 4.48 m²K/W Wall (incl. air spaces): 4.91 m²K/W Floor (incl. air spaces): 6.24 m²K/W Emittance: 0.05 These values demonstrate SF60’s suitability for applications requiring very low U-values within restricted build-up depths. What does R-Value mean? R-Value (m²K/W) measures a material’s resistance to heat flow.The higher the R-Value, the better the insulation performance. What does Emittance mean? Emittance measures how much heat a surface emits (radiates). A low emittance value (typically around 0.05) means very low heat emission and high reflection of radiant heat, improving overall thermal performance when installed with adjacent air spaces. This interpretation is aligned with EN 16012 and reflects how reflective multifoil insulation performance is evaluated across EU technical documentation. Performance vs Traditional Insulation Thanks to its multi-layer reflective foil construction and integrated air spaces, SuperFOIL SF60 can achieve thermal performance typically associated with very thick traditional insulation systems, while significantly reducing overall build-up depth. In real-world constructions, SF60 enables designers and contractors to meet stringent thermal targets without excessive wall, roof, or floor thickness — particularly valuable in space-restricted designs and retrofit projects. Exact U-values depend on the full construction build-up. Bespoke U-value calculations are available for project-specific compliance. Key Benefits Highest thermal performance in the SuperFOIL multifoil range Slim alternative to very thick traditional insulation systems Replaces insulation, vapour control layer, and radiant barrier Easy to install – no specialist tools required Lightweight and flexible despite high performance Minimal waste compared to rigid insulation boards Suitable for new builds and retrofits Can be combined with other insulation types Made from up to 40% recycled materials Fully recyclable with a 50+ year service life Applications SuperFOIL SF60 is suitable for use in: Pitched and flat roof constructions Internal wall systems Timber-frame and solid wall constructions Floor structures It is typically installed on the internal side of the building envelope as part of dry-lining systems.
