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 high thermal insulation properties of wood (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, heat from high summer temperatures is not transmitted indoors, and winter heating is not lost to the outside. Breathing wood is truly a living material. Just as temples and shrines endure, wood continues to live on through proper maintenance. 【Features】 ○ Air tightness, thermal insulation, sound insulation → No worries about heat escaping from windows or condensation, equipped with performance comparable to walls. ○ Durability → Wooden frames do not burn away and are less likely to be damaged by 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 with various opening methods and a wide range of window designs.
