Abstract
This utility model relates to the field of doors and windows, specifically to an energy-saving window frame and window system for curtain walls. The energy-saving window frame includes a sub-frame profile made of glass fiber reinforced composite material. A first end of the sub-frame profile is fixedly connected to a steel keel by a first screw. A second end of the sub-frame profile has an installation chamber containing a liner. A second screw passes through the liner and is fixedly connected to a pressure block. This utility model, by using a sub-frame profile made of glass fiber reinforced composite material, extends the heat transfer path, significantly reduces the thermal bridging effect, and thus achieves the goal of reducing the heat transfer coefficient. It is energy-saving and environmentally friendly, possessing good economic efficiency and practicality. The liner in the installation chamber effectively increases the screw holding force and enhances connection stability.
