The greenteQ new building window profile without masking edge has a fixed side limit stop (must not be removed). It is suitable as a low-priced alternative for larger properties. The greenteQ new building window profile without masking edge can be used both indoors and outdoors. A specially shaped profile made from hard PVC with a special double-sided adhesive sealing tape (permitted sealing tape expansion > 200%) continuously absorbs any stress that occurs. Bothersome cracks in the plaster on the window are prevented. In addition, plaster and mortar residues cannot get into the expansion space behind the window. The greenteQ new building window profile with masking edge fulfils all state-of-the-art requirements for interior and exterior sealing during window assembly.
