The first products family, designed and presented with the brand name Material City, is soft family profiles with 3 chambers and a cross-section of 52mm. The family complies with all the industry’s standards, and the products have a graceful appearance. They match most of the customers’ budgets and tastes and are the best choices for mass-construction projects. In the doors and windows produced by the family’s profiles, two waterproof gaskets are used. It is possible to install 24-millimeter double and triple-glazed glasses (thickness: 4 and 6 mm.) for the windows.
