Description

Technical Field

[0001] The utility model relates to the technical field of door and window profiles, in particular to a PVC window sash buckle structure capable of replacing indoor decorative profiles. Background Art

[0002] Currently, the main types of windows and doors include plastic windows, aluminum alloy windows, and wooden windows. Plastic windows are superior to other materials due to their low material cost, ease of processing, and lower thermal conductivity. However, the texture and strength of the PVC profiles used in plastic windows are inferior to those of solid wood and aluminum alloy profiles. Users seeking the natural texture and thermal insulation properties of solid wood often have to bear the high price of wooden windows. Aluminum alloy windows, while similar in price to plastic windows, have significantly lower thermal insulation performance.
