Furthermore, half of the window frame is housed within the casing, effectively making the entire frame over 50% slimmer.

In European architecture, many openings such as windows and entrances, which serve as the boundary between the interior and exterior of a home, utilize wooden frames. This is due to the wood's high insulation performance (thermal conductivity of 0.12), its soothing qualities that evoke a sense of comfort, and an understanding of the importance of protecting the earth's natural environment. By using organic wooden frames, high summer temperatures are not transmitted indoors, and winter heating is not lost to the outside. The breathing wood is truly a living material. Just as with temples and shrines, wood continues to live on through proper maintenance. 【Features】 ○ Air tightness, insulation, soundproofing → There is no worry about heat escaping from the windows or condensation forming, as they are equipped with performance comparable to walls. ○ Durability → Wooden frames do not burn away and are less likely to deform from heat, making them more fire-resistant than aluminum frames. ○ Health and comfort → Wood has moisture-regulating properties and is a user-friendly material that provides a sense of tranquility. ○ Design and color → Wooden frames come in various opening methods and a wide range of window designs.
