This is a cover method product that allows for the replacement of new windows while keeping the existing window frames. Unlike conventional cover methods (which use screws and hardware for fixation), this method uses specially developed polyurethane for fixation, preventing heat loss from the gaps between the existing sash frame and the new sash frame. Additionally, the adhesive strength is approximately ten times greater than that of traditional methods. This method can be used to replace any type of existing sash, regardless of its type, material, shape, or the type of structure. The newly installed windows use high-performance K-WINDOW, which improves insulation and creates a more comfortable window area after replacement.

"K-WINDOW" is a high-performance insulated window that incorporates multi-layer glass into a resin frame developed at our factory, utilizing the computer production system from Canada's P.H. Tech. We offer a variety of high-performance multi-layer and triple-glass options that can either capture or block solar heat while minimizing indoor heat loss. These are provided according to the specific needs of residential areas. Additionally, while the exterior appearance of the frame remains the same, we have implemented a multi-chamber structure that suppresses internal heat convection, enhancing insulation performance. 【Features】 ■ High-performance multi-layer glass ■ Sturdy frame ■ Multi-chamber structure frame ■ Versatile installation options *For more details, please download the PDF or feel free to contact us.
