Product Guide for Sealing Windows and Doors
A significant portion of air leakage, specifically 30 percent, penetrates through windows and doors. By properly sealing these openings, you can prevent air leakage while saving both time and money through reduced energy consumption and maintenance. In TECCA's product guide, you will gain in-depth insight into the best ways to seal windows and doors. We base our recommendations on three different sealing methods and present the products we recommend to achieve optimal results.
When you begin the installation of windows or doors, it is crucial to start the process with a secondary seal at the bottom of the installation opening, regardless of the method you choose. The role of the secondary seal is to ensure effective moisture protection against the frame, especially in the event of potential water intrusion through windows and doors.
Step 1 - Secondary Sealing
The secondary seal consists of the flexible and elastic sealing tapeFlexseal-T that adheres to concrete, wood, steel, windproof fabric, or boards
Step 2 - Choose a method for sealing windows and doors

How much material is needed?
In our calculation tool, you can easily calculate how much material is needed for the different methods.
Airtight-T - a vapor-permeable construction tape that seals and adheres to many different surfaces
Airtight-Tis a diffusion-open construction tape made of material equivalent to a windproof membrane. Its range of use is broad because the tape has good adhesion to many different materials. This makes it suitable, for example, to use as protection on underlying facade or structural details. The taped details become both aging-resistant and sealed.
- Adhesive that works even in low temperatures
- Vapor-permeable and waterproof
- The tape is UV-resistant during the construction period
- Split protective film simplifies installation
- Good adhesion on many frame and board materials, as well as wind protection fabrics
- Durability even on alkaline surfaces such as concrete and plaster
