Reason One Minimal is the aluminum-wood system with thermal break designed to bring more light indoors, while maintaining the high performances that distinguish the products remain unchanged Starwood. In fact, technological research has made it possible to reduce the thickness of sash and frame profiles and the central node in the double-leaf windows, allowing to gain more than 20% of glass surface. The result is the sensation of lightness given by the reduced thickness of the visible profiles, the squared door and the central position of the handle in double-leaf systems.Possibility of extension from the basic set with: P5A anti-vandalism ethers (withstand the impact of 9 objects weighing 4.10 kg with a 9 m drop); perimeter hardware with anti-tear system and multiple locking points as per RC2 diagram. Glazing upto 36mm and And frame depth 95.5mm . Air tightness of level 4 ,water tigtness 9A And windload C5 . Acoustic Performance 44dB And thermal Insulation 1.7 W/m2K .
