"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.
