The Intelligent Membranes Fleece Airtightness Tape is designed for professional builders and DIY enthusiasts seeking a high-performance, long-term sealing solution for windows, door frames, and critical building junctions. Its primary benefit is a unique moisture-dependent SD value that dynamically regulates vapor flow to ensure a durable, breathable, and airtight seal in both new builds and renovations. While this tape provides an exceptionally robust bond, users should note that optimal performance requires a strictly clean, dry, and dust-free surface to ensure the aggressive adhesive adheres correctly.

Yes, the non-woven fleece surface is designed to be fully paintable and plasterable.
Yes, it is designed for both internal and external sealing junctions provided the application surface is clean and dry.
While it does not have a strict expiry, store in a cool, dry environment to ensure the adhesive remains effective for the long term.
The tape features a moisture-dependent SD value, meaning it adjusts based on the relative humidity of the environment.
No, the surface must be completely dry and free of dust for the adhesive to function correctly.
This specific roll is 150mm wide and 25m long.
Ensure the surface is dry and free of dust. Use a brush or vacuum to clean the area before application, or consider a primer for highly porous surfaces.
Use a pressure roller to firmly work the adhesive into the substrate. Avoid over-stretching the tape during application, which can create tension and cause lifting.
To achieve the best results, ensure the substrate is structurally sound, clean, and entirely free of dust, grease, or loose debris. If the surface is porous, consider applying a primer to improve bond strength. When applying, firmly press the tape into place using a specialized pressure roller to activate the adhesive across the full width. The tape is compatible with most standard building materials, including timber, blockwork, concrete, and metal frames. For storage, keep rolls in a cool, dry place away from direct sunlight to preserve the integrity of the adhesive backing. If the tape is being applied in cold temperatures, keeping the rolls in a warmer area before use can improve the flexibility and initial tack of the adhesive.
