The solid wood and aluminum composite window is designed multiple hollow type aluminum frame work structures, which forms the continuous separation sections for heat preservation. In the middle the nylon 66 separates the wood and the aluminum to preserve heat. Compared to the products designed one hollow, the external appearance, heat preservation property and the strength of our product are more superior.The frame corners of the solid wood are jointed by the combination of the tenon connection type and the nail-connection type. The tight joint avoids splitting.
