About Brand TOSTEM

TOSTEM is a globally recognized brand of windows and doors. It is a part of LIXIL, Japan’s most respected name in building materials, housing products and services.

We started designing and manufacturing aluminum sash windows in 1967 based on the principles of always aiming for the highest quality and never merely imitating what others had already done. As lifestyles and customer expectations have changed and diversified over the years, we too have evolved to meet them, continually enhancing the performance and comfort of homes. Our products allow people to be both connected to nature and protected from the elements – a durable interface that enhances comfort and wellbeing.

As the leading Japanese brand for global housing and building materials, TOSTEM stands apart as a one that deeply understands the needs of people. TOSTEM’s comprehensive range of solutions ensures comfortable home living driven by a simple and seamless user experience.
