The best air permeability performance for sliding
Schlegel G3-QF (Quadrafin) is the new brush seal with an extruded base for sliding windows and doors, designed with advanced features that make it the ideal solution to counter air infiltration.

- Double-raised center fin that provides a more effective barrier against air infiltration (see comparative table);
- More flexible base, easy to fit into even the narrowest channels;
- Thicker silent fins that provide optimal air tightness without annoying noise.
