LIXIL Corporation (LIXIL) has announced a new addition to its eco-friendly window line, “GREEN WINDOW,” featuring windows crafted from domestic solid wood, expected to launch in 2025. Known for its natural warmth and sustainability, this new product line aims to enhance both comfort and environmental responsibility in residential spaces.

Combining Domestic Wood and Aluminum Structure for High Insulation and Design Appeal

LIXIL’s “GREEN WINDOW” series focuses on reducing environmental impact while enhancing residential comfort. This new lineup, made with domestic wood, utilizes Japan’s rich forestry resources to create windows that balance insulation performance and visual appeal. Leveraging TOSTEM brand expertise, the windows combine the warmth of wood with the durability of an aluminum-clad structure, enhancing longevity and providing high thermal insulation.
Wood is a natural material known for its insulation properties, and it contributes to CO₂ absorption and reduced transportation emissions. By sourcing wood from sustainably managed forests within Japan, LIXIL supports forest conservation. Additionally, these windows align with the current trend toward natural materials in homes, harmonizing with interior aesthetics through the unique beauty of solid wood.
Starting with sliding windows commonly used in Japanese homes, these new products offer improved decay resistance, making maintenance simpler and extending product life. Through TOSTEM’s refined design and technological expertise, LIXIL continues to deliver windows that connect people with nature.
LIXIL plans to further its commitment to environmentally friendly product development, focusing on designs that celebrate Japan’s unique seasonal beauty. Additional product details will be announced in upcoming press releases as available.
