OMD’s double casement solutions offer dual-sash functionality with aluminium frames, designed for optimal airflow and thermal performance. The windows can be configured with one fixed and one opening sash or both operable, providing flexibility in ventilation control. The aluminium profiles are powder-coated to resist fading and corrosion, while the glazing options include Low-E glass for solar control and laminated glass for safety. These windows are tested to withstand 9 级 wind loads, making them suitable for coastal regions.
