Unique Slide & Vent solution.

What makes PATIO AIR special is unique micro-ventilation option. Instead of tilting, the sash releases the pressure off the gaskets and creates small gap around the frame to enable circulation of fresh air while maintaining full security. Available in full range of PREMIUM window profiles, meets the highest energy-efficiency and soundproofing standards.





All Our Premium windows and doors are produced by VETREX Ltd. - one of the leading window manufacturer in Europe. All the components are specially selected to assure highest quality, functionality and energy-efficiency.
