Stala window assemblies are custom-made for any size and design of opening. They typically come in fourteen-gage steel. Window solutions come with dimensions having been factory-checked and thus are ready to receive windows as soon as they arrive. Cased opening assemblies are also an option, offering a smooth frame that remains in place and accepts a typical hollow metal or aluminum window frame. All window solutions are available thermally broken. The thermal break prevents heat and cold transfer. For more information, see Thermally Broken Solutions. Our window solutions include additional features such as drywall returns, masonry ledge, vibration pocket for contractor access during concrete pour, and exterior brick facades to name a few.
