T-Expand Pro
Pre-compressed drive band of impregnated PUR (Polyurethane) foam with edge (inside) equipped with polyethylene film (vapor barrier) and underside with adhesive strip for quick and easy installation. The exterior side is diffusion-open but protected against driving rain and waterproof up to 1000 Pa. The tightness ratio (diffusion) outside-inside is 1:50. The drive band's PUR foam is thermally and acoustically insulating.
High sound insulation and good thermal insulation
Thin (not expanded) with easy installation
Sealing tape on the inside and outside is not required
Weather and UV protected
Application Area
For sealing and jointing during the new installation of windows and doors, primarily in insulated constructions. The sealing tape has a diffusion-tight inside, a diffusion-open outside, a waterproof outside, absolute airtightness, good thermal insulation capability, and sound insulation. It can be exposed to weather and sunlight for a long time.
Installation
The installation is carried out according to the installation instructions with adhesive tape around the frame on the window/door. After fixing the frame in the section, wall, or ceiling, the expanding foam tape self-expands so that the joint is completely sealed and tightened. For complete information, see the installation instructions.
Important!
- The band with the expansion area should be selected based on the size of the caulking gap. The actual gap should be within the expansion area to achieve relevant properties!
- The window/door frame must be clean and dry when applying the sealing strip.
- Should be stored dry in a sealed package and protected from sunlight.
- Storage temperature +1°C to +20°C.
- After using a started roll, it should be promptly resealed with sealing tape for future use.
- In colder weather, the expansion time can be significantly extended. Up to several days in some cases. Elevated temperature or gentle heating accelerates the process.
