SuperFOIL SFNC+ Non-Combustible Multifoil Insulation – Euroclass A1 Fire-Safe Solution

SuperFOIL SFNC+ is a non-combustible, fire-rated multifoil insulation designed for projects where the highest level of fire safety is required without sacrificing thermal performance or build-up efficiency. With a nominal thickness of 20 mm, SFNC+ delivers reflective thermal insulation combined with a vapour control layer and radiant barrier in a single, ultra-slim system.

SFNC+ is specifically developed for commercial buildings, high-rise projects over 18 metres, and applications where Euroclass A1 non-combustibility is mandatory.

For non-combustible systems such as SuperFOIL SFNC+, internal comparative assessments indicate that equivalent thermal performance varies according to product thickness, installation method, air gaps, and overall construction build-up and should be considered indicative only. 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. Due to differences in thickness and fire-rated construction requirements, SFNC+ performance comparisons should be assessed using the certified R-Values of the product and the specific construction build-up, and are provided for indicative comparison purposes only.

3-in-1 Multifunctional Design

SuperFOIL SFNC+ combines three essential functions in one product:

• Reflective thermal insulation

• Radiant barrier reflecting up to 97% of radiant heat

• Integrated vapour control layer (VCL)

This integrated design reduces the need for multiple material layers while supporting both thermal efficiency and regulatory compliance in fire-sensitive constructions.

Fire Performance – Non-Combustible

SFNC+ is the safest insulation product in the SuperFOIL range.

• Euroclass A1 – Non-Combustible

• Will not ignite, burn, or contribute to fire spread

• Reduces risk of fire transmission between compartments

This makes SFNC+ suitable for buildings over 18 m, healthcare facilities, education buildings, commercial developments, and other high-risk environments.

Non-Combustible Insulation for High-Risk Buildings

Thermal Performance

Despite its slim 20 mm thickness, SFNC+ delivers certified thermal performance when installed with air spaces.

Certified thermal performance (core value + air spaces, EN 16012):

• Core R-Value: 0.67 m²K/W

• Roof (incl. air spaces): 1.53 m²K/W

• Wall (incl. air spaces): 1.95 m²K/W

• Floor (incl. air spaces): 3.28 m²K/W

• Emittance: 0.05

These values demonstrate SFNC+’s ability to provide meaningful thermal resistance while meeting strict fire safety requirements.

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 Fire-Rated Insulation

Traditional non-combustible insulation systems often require significant thickness to achieve comparable thermal performance. SuperFOIL SFNC offers a space-saving alternative, delivering reflective thermal efficiency with a minimal build-up depth.

This makes SFNC+ particularly valuable in retrofits, façade upgrades, and space-restricted high-rise designs.

Exact U-values depend on the full construction build-up. Project-specific calculations are available.
