casement transom window
A casement transom window represents a sophisticated architectural element that combines the functionality of two distinct window types: a casement window and a transom window. This innovative design features a main casement window that opens outward via side hinges, topped by a fixed transom panel that allows additional natural light to enter the space. The window system typically incorporates advanced weatherproofing technology, including multiple sealing points and robust locking mechanisms, ensuring optimal protection against environmental elements. The construction usually features high-grade materials such as vinyl, aluminum, or wood frames, complemented by energy-efficient glass options. These windows are engineered to provide superior ventilation control, with the casement section offering full opening capabilities while the transom maintains constant light transmission. Modern versions often include thermal breaks, low-E glass coatings, and multi-point locking systems that enhance both energy efficiency and security. The design is particularly valuable in spaces where both maximum ventilation and consistent natural lighting are desired, making it an excellent choice for residential and commercial applications.
