Housing & Building

LIXIL is a maker of pioneering housing products. Through our portfolio of brands including TOSTEM, EXSIOR, INTERIO, and SUPER WALL, we offer window sashes, doors, exterior building materials, and interior furnishing materials that help make a better home a reality.

We believe that windows and doors do more than connect you with the world outside; they help keep us healthy and comfortable, whether in summer or winter. We consider interior and exterior materials as more than just functional components; they also bring spaces to life and link your home to your lifestyle and persona.

Building on the technology and quality that we have nurtured over the last 50 years, we continue our quest to deliver more satisfaction to people's everyday lives. Our hybrid windows harness the material strengths of aluminum and resin to provide a high degree of insulation. Our Super Wall construction method helps maintain comfortable temperatures in the house while adding seismic resistance. We are even developing smart home products utilizing the Internet of Things (IoT) and next-generation homes assisted by AI and smartphones.

At LIXIL, we focus on enhancing product design and providing intelligent functionality to deliver additional comfort, health, and happiness to people, helping make the house a home.
