Having selected a partner to manufacture your windows or doors, there are several points to pay attention to during the delivery and installation of the frames you have chosen. A very important detail! During installation, the frames must not come into direct contact with the walls or floor; otherwise the thermal insulation is negated. In between the frame and the wall or floor, plastic wedges and special insulating materials must be placed all along the edges, in order to preserve the thermal insulation properties of your window or door and all joints must be sealed with silicone.
All windows must have special holes in their frame for the drainage of water that collects from rainfall and humidity. These holes are covered with special caps. Window sashes must also have holes for water drainage, on the bottom profile as well as on the top.
Fabricators should provide customers with Quality Guarantees for all products that have been installed. The
minimum guarantee duration is two (2) years. With correct use, maintenance and cleaning, a customer contributes both to their problem free and flawless appearance.
Also, you
should receive the special CE mark document from the manufacturer. This is mandatory in accordance to European Union (EU) standards for every home-use door or window. CE stands for the French words "Conformité Européenne ", which means
European Conformity. CE in no case indicates the quality of the materials, but only the safety for the final user. Products that do not bear the CE mark are not allowed to be on the market in the European Union, which means they are illegal.
