Aluminium Top hung (awning) windows Aluminium Top hung (awning) windows are the ideal choice for suburban environments that have multi-unit residential homes, semi-commercial applications and hotels. The windows can integrate into a number of commercial framing systems as long as they use awning adaptors. The awnings are operated using chainwinders, and they use the chainwinders adaptor with the security screens that may be added within the doors. Before you use these windows, you should first look at the frame dimension, maximum product performance, glazing details, compatible systems, and the maximum recommended sizes. The windows can be compatible with insect screening or screening for children.
