Aluminium windows offer slim sightlines, strength, and a contemporary appearance.
The ultra-slim 59mm sightlines 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 multi-point locking and unique hinge protectors, creates unparalleled levels of security.
As an alternative, you might want to consider our Prestige Aluminium Window.
