The EXTRALUSSO ( extra luxury) model has a 68 x 82 section with three gaskets. Every window of the Vertaglia range has a fixed “Z” frame: this avoids the use of inside wire covers, which are often unaesthetic and do not allow the sash to rotate 180°. 68 windows present on the market usually have two gaskets: Vertaglia designed EXTRALUSSO with three gaskets between the sash and the frame to ensure the maximum seal from weather conditions. A burglar proof version RC2 is available upon request.
