Style: TB 4000
Bring the outdoors inside—even during a light rain. Portella thermally broken awning windows are hinged at the top so that you can push out the sash and ventilate hot air while keeping drizzling weather outside. Perfect for a clerestory to keep light in and allow hot air to escape. Made of solid steel, our awning windows can be automated or manually operated by a crank and are similar to the construction of our hopper window.
