Description
IFLEX is a high-performance reflective vapour barrier for walls and ceilings. Installed between drywall and insulation, it blocks humidity and boosts energy efficiency by increasing the R-value of the system thanks to its reflective surface.

Material Use:
SOPRA-FOIL IFLEX is a high-performance reflective vapour barrier designed to control moisture and improve thermal efficiency in building envelope assemblies. It is particularly effective in reducing radiant heat transfer when installed with an appropriate air gap, making it suitable for use in walls, ceilings, and floors where vapour control and thermal performance are required.
System Components:
SOPRA-FOIL IFLEX is a standalone vapour barrier system composed of a metallized polyethylene surface for reflectivity and a black polyethylene underside. It is typically used in conjunction with insulation systems but must not be combined with other vapour barriers. Installation accessories may include staples or nails for fastening, spacer or furring strips to create an air gap, and sealing tapes or compatible sealants to ensure airtightness.
Applications:
This material is ideal for use in residential, commercial, and industrial construction where a vapour barrier is required on the warm side of the insulation. It is suitable for use in wall cavities, attic spaces, and under roof decks, particularly in cold climates where vapour diffusion control is critical.
Application Details:
SOPRA-FOIL IFLEX must be installed on the warm side of the building envelope to prevent condensation within the wall or roof assembly. It is fastened using staples or nails, and the use of furring or spacer strips is highly recommended to maintain an air gap of 1.25 cm to 5 cm (0.5 in to 2 in), which is essential for maximizing the reflective properties of the material. All seams, joints, and penetrations must be sealed with appropriate tape or sealant to ensure a continuous vapour barrier. The product must not be perforated during installation.
Special Notes:
- Compatibility: Do not install SOPRA-FOIL IFLEX in conjunction with any other vapour barrier. If an existing vapour barrier is present, it must be removed or perforated to prevent double vapour barrier conditions, which can lead to condensation and moisture damage.
- Environmental Conditions: The product is designed to perform in service temperatures ranging from -45 °C to 82 °C (-50 °F to 180 °F).
- Storage: Rolls must be stored upright in a dry, heated area to prevent condensation and maintain product integrity.
- Physical Properties: The material has excellent elongation properties (800% MD, 900% XD) and tensile strength (28 MPa MD, 24 MPa XD), with a very low emittance value of 0.05, enhancing its reflective performance. Water vapour permeance is 2.04 ng/Pa•s•m² (0.036 perm) as received, and 7.07 ng/Pa•s•m² (0.124 perm) after aging, conforming to Type 1 vapour barrier standards.
- Thickness and Dimensions: The material is 0.076 mm (3 mils) thick and comes in rolls measuring 1.32 m (52 in) wide by 31.6 m (104 ft) long.
SOPRA-FOIL IFLEX is a reliable and efficient vapour barrier solution that enhances energy efficiency and moisture control when properly installed as part of a building envelope system.
