Vapor barrier foil Tytan FM PI 2*50 — 0.2 mm thickness, 2 m width, 50 m length

Tytan vapor barrier foil FM PI 2*50 is a polyethylene membrane designed to control moisture migration within building envelopes. With a nominal thickness of 0.2 mm, a roll width of 2 m and a length of 50 m, this vapor retarder is intended for installation beneath roofing structures, inside exterior walls and under ceilings to protect thermal insulation and structural elements from interior-generated vapor. The product is compatible with both wooden and metal framing and provides a continuous vapor control layer that helps maintain insulation performance and reduce the risk of condensation-related damage.

Advantages

The membrane offers a consistent 0.2 mm thickness that balances durability and flexibility for easier handling during installation. Its 2 m width and 50 m roll length reduce the number of seams required on large surfaces, saving time in installation. Made of polyethylene, the foil is resistant to common building-site conditions and can be fixed with standard mechanical fasteners or adhesives. The continuous vapor retarder function supports indoor climate control and contributes to longer service life of the insulation system.

Suitable for

• Installation under roof coverings and in attic spaces
• Vapor control layer within exterior timber or metal stud walls
• Ceiling applications to protect insulation from internal moisture
• Use in renovation projects where existing vapor barriers need replacement

Key specifications

• Material: polyethylene membrane
• Nominal thickness: 0.2 mm
• Roll width: 2.0 m
• Roll length: 50 m
• Function: continuous vapor retarder / vapor control layer
• Compatibility: suitable for use with wooden and metal framing

How to use

Unroll the membrane with the printed or marked side as specified by the manufacturer facing the conditioned space if applicable, and align it across the surface to be covered. Overlap adjacent sheets according to local building codes or the installer’s best practice and seal overlaps with appropriate tape or adhesive to ensure a continuous vapor control layer. Fix the foil to framing members using staples, nails with washers, or compatible mechanical fasteners; in areas requiring increased airtightness, use compatible sealing tapes at penetrations and junctions. Trim excess material and ensure that the membrane is protected from sharp edges and prolonged exposure to sunlight during installation.

Usage recommendations

Store rolls flat in a dry, shaded area before installation. Avoid prolonged UV exposure; install finishing layers or protective battens as soon as reasonably possible. Follow local building regulations for vapor control placement relative to insulation and climatic conditions, and use appropriate sealing products at joints and service penetrations to achieve the intended vapor retarder performance.
