The STONE model has a 86 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°. It is the evolution of the wood-aluminum window: the window is identical to the LUSSO model but with an outside aluminum cladding. It can be made with RAL dyes or wood effect colors. It guarantees acoustic and thermal performance as a wood window. A burglar proof version RC2 is available upon request.
