The invention refers to a window seal testing installation, designed to test window seals against wind and rain, which can simulate standard conditions depending on the geographical area where the windows are to be mounted. According to the invention, the installation has a front panel (1), with the window to be tested (4) mounted on one side by means of a pressure box (3) and an assembling device (5), and a pressure chamber (2) mounted on the other side. In front of the front panel (1) there are a roller train (6), on which the window (4) is sat, and a rigid frame (7) on which some mobile bars (10) can move. Some trucks (9) that are connected to the pneumatic cylinders (8), engaged by a pneumatic distributor (11), glide along the mobile bars (10). The air necessary for wind simulation is created by a fan (13), through a piping (15) on which an anemometer (15) is mounted, and the water necessary for rain simulation is delivered by a pump (16) through some pipes (17) on which a rotameter (18) is positioned. The fan (13) can be actuated by a frequency converter (19), and the pressure transducers (12), which detect the pressure losses through the window (4), are connected to a computer (20) that records the data.
