Introducing the benefits and considerations of incorporating transoms, as well as architectural design and practical examples!

In architectural spaces, "ranma" is not just a decoration. As a traditional fixture that enhances the space with light and shadow while maintaining daylight and ventilation, it is being reevaluated in today's modern Japanese homes and renovations. However, during the design, ordering, and construction phases, various considerations such as insulation, airtightness, and fitting adjustments come into play. This article will start by explaining "what ranma is," followed by a comprehensive discussion of the characteristics of different types, such as carvings, openwork, kumiko, and shoji, as well as price ranges, possibilities for remaking and purchasing second-hand, design examples, and key points during ordering and construction. Additionally, it will touch upon the advantages of Sakumiru, which supports core business functions for construction companies (such as estimating, scheduling, customer, and billing management), providing practical information that can be immediately useful. *For detailed content of the article, please refer to the PDF document. For more information, feel free to contact us.*
