Description

Window frames with enhanced earthquake resistance and insulation through a reinforced joint structure and windows including the same {WINDOW FRAME WITH ENHENCED ASEISMICITY AND INSULATION, AND WINDOW HAVING THE SAME}

The present invention relates to window frames and doors that support windows, and more specifically, to window frames and doors with enhanced earthquake resistance and insulation through a reinforced joint structure.

In general, window assemblies refer to various windows or doors installed in openings such as windows or doorways to block the inside of a building from the outside. Depending on the material used, wooden window assemblies, metal windows, or plastic system windows, etc. It can be classified as:

Such windows include a glass panel and a window frame coupled to the circumferential surface of the glass panel, and are installed to be hinged or sliding on a window frame built in an opening in the wall.

In particular, as modern buildings become taller and denser, the size of windows inevitably increases. Aluminum is excellent for its high strength, low expansion and contraction, excellent durability, and a higher ignition temperature than existing PVC. However, aluminum has a high thermal conductivity, It has the disadvantage of large losses due to convection. The factor that reduces window performance in most cases is the large heat loss of the aluminum frame. The performance of a window is evaluated as the average value of glass and frame, and the heat loss is much greater in frames using aluminum than in glass panels using low-e film.

To solve this problem, composite windows that connect aluminum with an insulating material are being applied. However, composite windows have a problem in that their earthquake resistance is reduced due to weak strength at the connection portion.
