T-Flex

T-Flex is a high-performance original tape with extensive market experience. The sealing tape is diffusion-tight and has a wide range of applications as it can be used both indoors and outdoors. T-Flex has optimized properties that provide high adhesive strength and long durability. The tape is made of a co-polyethylene, reinforced with polyester threads, and coated with an aggressive acrylic adhesive. A silicone-coated release paper serves as adhesive protection. The materials used are free from toxins and solvents. The version with split protective film (slit) is optimal for taping at angles.

Very good adhesive strength
Age-resistant for at least 50 years
Can be used indoors and outdoors
Wide range of applications, tested at RISE on many different surfaces

Product Information

Application Area

T-Flex is used as moisture and air sealing tape indoors and outdoors. For example, for joints, penetrations, or damages on vapor barriers (PE foil), vapor brakes/wind protection (Non Woven), aluminum-coated insulation board, PVC, wood (planed or lacquered), corrugated cardboard, glass, and metal, etc.

Harmful moisture and vapor are prevented by the tape from being transported in or out to sensitive building parts (prevents convection and diffusion). The tape also functions as weather protection externally on the outer climate shield's wind protection layer. In a system installed for the inner or outer part of the climate shield, the tape counteracts energy losses (heat leakage) in insulated constructions.

The product comes with a 30-year product warranty and is also included in a 30-year functional warranty. See separate terms.

Installation

The tape is always applied to the surface with firm and strong thumb or finger pressure. Post-processing is preferably done with a roller or plastic spatula. See the applicable installation instructions.

Approval

System testing (according to standard SP5264) has been carried out by RISE (Research Institutes of Sweden) as well as testing of age resistance for P-marking (SPCR031).

Important!

Note that movements in the substrate should be minimized for optimal durability and test the adhesion on the substrate before installation.
The surface should be clean (consider surface treatments), grease-free (silicone-free), dry, and smooth. Follow the recommended working temperature for best results.
Do not stretch the tape too elastically as it will always try to return to its original shape and width.
Consider forces and movements in the underlying foil (or membrane). Especially free-hanging and non-fixed substrates where temperature fluctuations (e.g., temporary higher temperatures during construction) can create tensions and movements in the tape joint due to the influence of self-weight!
Ensure that the base is properly secured and fixed according to the accompanying installation instructions or reinforce the taping (support tape, wider tape) corresponding to the additional load that may occur!
When assembling in lower temperatures, the tape should be stored in a warm storage before assembly for the best assembly results.
When taping at lower temperatures: The tape will achieve its final strength when the temperature is above
+5°C. The installation and application against the substrate should be compensated with higher pressure! In general,
tape applications should be free from tensile stress. This should be particularly considered at low processing temperatures.
To ensure age resistance, the tape should be stored or installed in the operating environment protected from sunlight (UV radiation) and not exposed to temperatures above +35°C.
For identification, always tape up the first piece with the label visible!
For outdoor use with wind protection fabric, the tape should not be exposed to sunlight (UV radiation) for more than a maximum of 4 months. For wind protection boards, the exposure time should be shortened, or T-Flex Outdoor, which is optimal for outdoor use, is recommended
