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.
