Applus+ mark: the best quality guarantee on the market for your glass


As enclosure elements or parts thereof in buildings, glass in building must meet certain requirements of durability and thermal and acoustic comfort that provide optimum conditions for users to go about their daily activities.

Sales of windows and glass enclosures in Europe are regulated by the Construction Products Regulation, which involves CE marking of this product. In Spain, when the window is part of an enclosure system, the Technical Code for Building Construction (CTE) is also applicable, requiring additional features according to its use.

The Applus+ quality mark for windows and enclosures shows that all regulations are fulfilled (CE and CTE), to obtain an excellent product that is perfect for its intended use. Likewise, it includes verification and assessment of all the production inspections, complete characterization of the product and periodic follow-up, enabling manufacturers reliably to inform their customers that the features of their products are adequate and durable, making it easier to advertise and sell their products. Applus+ certification is based on requirements defined with strict technical and market-related criteria by a group of product experts and administrators.
