The Tatra performance sliding sash window was designed around triple glazed vacuum glass. This unit is considerably thinner than effective triple or quadruple glazing units, which replicates the style and sections of a traditional British sliding sash window, while also achieving extreme energy efficiency. A highly traditional beading detail is incorporated to give the windows and doors a classically styled appearance.

Constructed from FSC-Certified Accoya® with a proprietary vacuum cavity unit and a specially adapted Italian paint system the range combines energy efficiency and an extended low maintenance service life into a well-designed package suitable for most styles of building.
