North American Crank Operation with a Fixed Interior Screen
This thermal break aluminum crank-out casement window uses a hand-operated crank to open the side-hinged sash outward. The operator makes controlled ventilation easy, while the fixed interior screen stays in place.
A 102mm system depth, 2.0mm aluminum profile, Low-E argon-filled tempered glass, and project-ready installation options make it a practical choice for North American homes, apartments, townhouses, modular housing, and light commercial buildings.
Why Choose a Crank-Out Aluminum Casement Window?
The main difference is how the sash is operated. The crank gives controlled outward opening, keeps the screen on the interior, and suits familiar North American window layouts.
Smooth Crank-Out Operation
The hand crank opens and closes the sash with controlled movement, making the window easier to operate than a large sash pushed directly by hand.
Fixed Interior Screen
The insect screen remains on the room side while the glass sash opens outward. Stainless steel mesh, fiberglass mesh, and aluminum mesh are available.
Strong 2.0mm Aluminum Structure
The heavier 2.0mm aluminum profile and 102mm system depth provide a solid platform for residential and project-based window packages.
Low-E Argon Insulated Glass
Standard 5mm Low-E + 12mm argon + 5mm tempered clear glass supports indoor comfort, energy performance, and everyday sound control.
High Water and Wind References
The latest specification lists 600Pa water resistance and wind pressure resistance up to 4000Pa for properly configured units.
Practical Residential Sash Range
The crank-out casement sash is available from 450–800mm wide and 600–1800mm high, with a maximum sash weight of 60kg.
Flexible Window Combinations
Choose a single crank-out sash, fixed window, opening sash with a fixed panel, or a configuration with a fixed insect screen.
North American Installation Options
Nail fin, mounting tabs, upper and lower subframes, and angle aluminum options help match different wall details and contractor installation methods.
