Please note the size requirements and specifications for the opening sashes of casement windows; prioritize guiding customers to design according to standard sash dimensions.
For the design of fixed window sizes, it is also necessary to consider the glass strength requirements, as well as the feasibility of processing, handling and installation. Generally, the surface size of 5mm insulating glass should not exceed 1500×1600mm, and the area should not exceed 2.5 square meters.(For oversized glass, please refer to the configuration requirements for oversized insulating glass.)
Before window and door design, it is necessary to know the thickness of the installation wall to select the corresponding series and wrapping sleeves.
When designing the handle height of conventional casement windows, consideration should be given to installing it at a distance of about 1500mm from the ground (1300–1600mm).
Standard windows with both width and height exceeding 2.5m must be split into frames and equipped with splicing strips. For special cases, special remarks should be made after communicating with the customer service.
