This window features a strong frame and sash – the perfect combination to fit large openings. This window type is quite popular: while the top sash doesn’t move, the window opens by sliding the bottom sash up. Exterior cleaning can easily be performed from the inside, as the bottom sash tilts in and is equipped with an easy to reach (and clean) half screen. The shape of the bottom sill is specially designed to prevent water accumulation.
