Double Hung windows
The vertical sliding system helps cope with size, dimensions, safety, and design – all the things you can’t do without in modern architecture.
The movement of the opening is performed through a specially purpose-made ganged balanced – free system.
Test of operation no. 2295 carried out by the Columbia University, U.S.A. proved that operating characteristics remained unchanged after 50,000 opening cycles.
This result is equivalent to opening and closing the window in actual operation once a day for no less than 137 years!
Combined opening of upper and lower wings enhances full rational air re-circulation and eliminates that annoying door banging that is typical of swing openings.
The absence of counterweights and the modern roller-tilt system make its operation exceptionally-smooth and easy.
Vertical sliding of wings definitively eliminates the problem of sharp edges in opened traditional wings that may cause home accidents.
The 100% silicon strips act as an uninterrupted weatherproof fullperimeter barrier.
Thanks to its vertical sliding system, solves the problem of wing opening space, allowing you to make the most of room space.
