The attic of La Herrería, a building rehabilitated by Cesar Portela and winner of the 2007 Aproin Award, receives light and is ventilated through a combination of GPL top-hung roof windows (S08 3373 model) and vertical and sloping elements GIL windows (S34 3373 model), mounted in grids with Velux’s joint sealing system, which ensures the installation’s absolute tightness.

Velux’s top-mount windows offer the ideal combination for an optimum use of light and effective ventilation, while providing more space and an unobstructed view from the inside, turning it into an attractive viewpoint, especially in low-pitched roof areas. They feature Insulating Glazing, highly advisable for north-oriented buildings due to their high resistance to the most adverse climate conditions (4 mm thermal film float inside glass + 16 mm chamber with Argon gas + 4 mm tempered outer glass).

The window is operated with a handle located at the sheet’s low part. Furthermore, it features a working stem on the top that can be used to open and close the ventilation blade –allows for interior ventilation with the window closed- or to guide the sheet 180°, making the cleaning of the outer glass easier from the inside. According to the company’s press release, in order to complete the windows, some electric darkening curtains were installed in the sleeping rooms and electric shading devices in the rest of the rooms. It includes a domotic curtain management system, with Velux’s interface.
