Additional gasket in Star door and Panel door

For better tightness and better thermal isolation in the Star door system and Panel Door, an additional central gasket has been developed – between the frame and sash. These are the PVC profiles GT422A, GT422B, GT422C, and GT422D, with an integrated click cover for hidden screws. Profiles are equipped with soft wings who divide space for closed chambers. Installed profiles increase the aesthetics of the door; especially in areas visible when the doors are open (a black surface was obtained).
