The ultra slim 59mm sight-lines of the innovative 'wrap-around glazed' Classic window system maximises the light flooding into your home, creating a refined architectural look. The innovative construction of the Classic window system eliminates the need for separate glazing beads, often an area of weakness in traditional window design. Instead the corner jointing method securely locks the glass away within a completely sealed unit. This coupled with high security multipoint locking and unique hinge protectors creates unparalleled levels of security.
