T-Vap Pro

T-Vap Pro is a vapor barrier with variable diffusion openness. The fabric has a more flexible so-called functional barrier that follows the longer intervals of humidity throughout the seasons and more effectively regulates the flow of vapor in the construction. The product is made of a fabric of Polypropylene (PP) and Polyethylene (PE) that is heat and UV resistant. In higher humidity during summer, the membrane opens and increases the possibility for drying inward. In winter, the effect is the opposite and the membrane closes. Moisture migration out into the construction is prevented, as well as harmful condensation in the colder layers. With the help of the vapor barrier, you create increased insulation capability and enable faster drying. A well-functioning vapor barrier protects the property and extends the lifespan of the construction while still allowing it to dry out in both directions.

  • Increased insulation capacity

  • Possibility for optimal drying

  • Variable moisture transport

  • Optimal for wet rooms

Application Area

T-Vap is primarily used as a vapor barrier (internal climate screen) and always provides a more moisture-secure solution in the exterior walls of thermally insulated buildings. However, it always contributes to an airtight construction and prevents harmful moisture and vapor from being transported to sensitive building parts. Energy losses are also minimized in heated spaces.

Additional advantage is given when used in the following constructions:

– Exterior walls in wet rooms (to avoid double waterproofing layers).

– In combination with thermal insulation of natural fibers.

– Renovation of older exterior walls with cellulose-based building materials (timber, fiberboard, planks, etc.).

– Houses with temporary heating such as holiday homes or garages.

T-Vap Pro should not be used in constructions where spaces with permanently high humidity are allowed (e.g., swimming pools). However, this does not apply to kitchens or equivalent bathrooms in residences.

 

Installation

The T-Vap Pro vapor barrier should be installed in a system with airtight joint aids such as T-Flex sealing tape or T-Stos butyl for penetrations, etc. See separate installation instructions!

Important!

  • When using diffusion-open climate screens compared to vapor barriers, the overall construction and function should be assessed from a moisture perspective. Even though the possibilities for drying increase, the initial moisture levels should be reasonable as all moisture transport occurs slowly! Ensure during construction that the building materials do not contain more moisture than allowed by practice. Ventilate sufficiently if needed before the construction is permanently closed. In case of doubt, consult a building expert.
  • For optimal effect of both membranes, the choice of interior surface layers should be considered in walls and ceilings. Denser coatings reduce the effect, while diffusion-open material choices and colors only minimally affect it.
  • Installed in a system with accessories always airtight. See separate installation instructions.
  • Store and keep packaged/protected from sunlight (UV radiation) or consistently higher temperatures (>35°C).
  • The fabric has freely exposed (not built-in) UV protection that corresponds to the construction time (<3 months). If in doubt regarding the use of the climate screen and its properties, consult a construction expert.
  • T-Vap Pro should not be used in constructions where spaces with permanently high humidity are allowed (e.g., swimming pools). However, this does not apply to kitchens or equivalent bathrooms in residences.
