SuperFOIL SFBA 2/2 Bubble Foil Insulation – Enhanced 3-in-1 Reflective Solution

Compared to SFBA MP, SuperFOIL SFBA 2/2 uses a higher-performing bubble foil construction, providing improved thermal performance while maintaining a slim, lightweight, and easy-to-install format.

SuperFOIL SFBA 2/2 is a multi-layer bubble foil insulation designed for use in roofs, walls, and floors. It combines insulation, a radiant barrier, and a vapour control layer (VCL) in one flexible product, making it ideal for new builds, retrofits, timber-frame construction, and DIY projects.

This is a vapour-closed bubble foil insulation designed for internal applications where reflective thermal performance and moisture control are required.

SFBA 2/2 provides approximately 15–20% higher thermal resistance than SFBA MP, while maintaining the same slim, lightweight bubble foil format — ideal where improved insulation is required without increasing build-up depth.

For enhanced bubble foil systems such as SuperFOIL SFBA 2/2, internal comparative assessments indicate approximately 15–20% higher thermal resistance compared to SuperFOIL SFBA MP, when installed with adjacent air spaces under typical installation conditions. As a general reference, internal comparative assessments indicate that SuperFOIL SFBA MP, when installed with air spaces on both sides, can provide thermal performance broadly comparable to approximately 50 mm of expanded polystyrene (EPS) or 30 mm of extruded polystyrene (XPS). Based on this proportional comparison, SFBA 2/2 may achieve correspondingly higher indicative thermal performance depending on installation method, air gap configuration, and overall construction build-up.

These comparisons are provided for indicative comparison purposes only. Exact thermal performance must always be verified using the certified R-Values of each product and, where required, project-specific thermal calculations.

Product Dimensions & Coverage

• Thickness: 6 mm

• Length: 25 m

• Width: 1.2 m

• Weight: 7.5 kg

3-in-1 Multifunctional Design

SuperFOIL SFBA 2/2 combines three essential functions in a single product:

• Reflective thermal insulation

• Radiant barrier reflecting up to 95% of radiant heat

• Integrated vapour control layer (VCL)

This integrated design reduces the need for multiple layers and improves overall thermal efficiency with minimal build-up depth.

Thermal Performance

SFBA 2/2 utilises low emissivity air gaps to maximise thermal performance when installed with air spaces.

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

• Core R-Value: 0.14 m²K/W

• Roof (incl. air spaces): 1.05 m²K/W

• Wall (incl. air spaces): 1.47 m²K/W

• Floor (incl. air spaces): 1.67 m²K/W

• Emittance: 0.05

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

Traditional insulation materials rely primarily on thickness and mass. SuperFOIL SFBA 2/2 delivers thermal benefits through reflective insulation technology, making it a practical solution where space is limited or where insulation is being upgraded.

Exact thermal performance depends on the complete build-up and air space configuration.
