Terrace door

We bring the outside indoors

Let the sun in! With a glass terrace door from SUNFLEX you can enjoy that outdoor feeling in your own four walls. Because our barrier-free, high-quality SUNFLEX glass walls can be opened completely so that you can enlarge your living room to the garden fence. In addition, even when closed they ensure maximum light flooding of your living space and a clear view outside. No matter whether for a new or existing building: SUNFLEX solutions offer numerous customisation options for every requirement.
