OMD’s fixed casement windows are non-opening aluminium windows designed for maximum light transmission and structural integrity. The frames are constructed with seamless welding for airtight seals, and the glass can be laminated or tempered for safety. These windows are often used in combination with opening casement or awning windows to create large glazed areas, such as in sunrooms or commercial facades. They are customizable in size and shape, including curved or angled designs, and are engineered to withstand high wind pressures.
