Based on the 4600 Series platform. This window is suitable for Non-impact coastal applications that require a DP50 design pressure. This window is positioned to be competitive in all areas in which a DP50 product is mandated by code. Suitable for multi-family projects as well as single family homes. This window has been tested to a design pressure of 50 (DP50). This means that the window can withstand a wind load of 180 MPH without the window breaking. A DP50 window also has to pass a water test with wind blowing onto the window at 54 MPH. The window will not leak with rain blowing against the window at 54 MPH. The window has a fully welded sash which is reinforced with galvanized steel.
