Doorwin’s products no matter the aluminum, solid wood, cladded wood or uPVC have been designed for one purpose: to offer your customers more beauty, performance and value than any other brand.


About the Project



The building was originally outfitted with single-pane aluminum windows, leaving a drafty, inefficient building. When the time came to replace the building's original windows, the building owner wanted to find energy-efficient windows that could be replaced from inside the building and provide a consistent look from the exterior. 


When replacing the existing single-pane windows, the goal was to find energy-efficient windows that would add value to the building. Since this is a commercial hotel project, the overall design of the building was considered in conjunction with the functional and safety aspects. Doorwin suggested client use our ALU+ series thermal break aluminum tilt and turn windows.


DOORWIN’s tilt turn window is a killer product for any situational performance. When you consider there is a requirement for safety, extreme weather performance, soundproof, and energy efficiency.
