3M™ Vapour Barrier Tapes
Explore the range of 3M™ All Weather Flashing Tape, designed for durable, airtight sealing in passive houses, passive house or passivhaus. Models such as Fast D, Fast F and Fast G offer advanced solutions for vapour barriers, protecting against moisture and optimising energy efficiency – build with precision and sustainability!
What is a Vapour Barrier Tape?
A specialised adhesive material designed to tightly seal joints, penetrations and openings in the building envelope, especially in passive houses or energy efficient construction. These tapes, like those in the 3M™ All Weather Flashing Tape range, prevent air infiltration and water vapour diffusion, protecting the structure against moisture, mould and energy loss. Manufactured with high-tack acrylic adhesives and strong backings, they are applied to windows, doors, structural joints and penetrations, ensuring a watertight seal that meets standards such as Passivhaus (maximum 0.6 ACH50). Their resistance to extreme conditions and their compatibility with materials such as wood, OSB or concrete make them a key solution for sustainable construction.

Applications for 3M™ Vapour Barrier Tapes
8069E
- Primary use: Sealing penetrations (pipes, ducts) and complex joints in passive house envelopes.
- Benefit: Its double-sided design and multi-layer elastomeric backing ensures a robust seal around structural elements, ideal for transitions between substrates such as concrete and wood.
- Example: Sealing electrical cables or ventilation pipes in foundations, ensuring continuity in the air barrier.
8068E
- Primary Use: Sealing structural joints and penetrations in exterior walls subject to movement or stress.
- Benefit: The reinforcing grid provides superior tear and tensile strength, ideal for applications in highly demanding areas.
- Example: Sealing joints between prefabricated panels in passive houses, ensuring durability against thermal changes.
8067E
- Primary Use: Sealing around critical openings such as windows and doors, especially frames and thresholds.
- Benefit: Thin backing minimises bulk under cladding, ideal for watertight sealing in critical areas of the envelope.
- Example: Sealing jambs and headers on timber windows, compatible with water barrier systems.
