TP654 is an impregnated, pre-compressed multi-functional window sealing tape based on 2 new technologies:
1. A 3-layer foam structure: the grey foam is an airtight closed cell foam which provides a 100% secure airtight connection to the window frame and the wall. The black foam has a slow recovery time which allows a successful installation.
2. An airtight layer is inserted inside the tape, connecting the grey foam and the black foam from the top to the bottom. Combined, these 2 technologies provide a high-performance sealing level with a driving rain resistance up to 1050 Pa and an airtightness level more than double the requirements.
