The amount of wind that a house window can withstand depends on a number of factors, including the type of window, the materials it is made from, and the design of the window. In general, windows that are designed to withstand high winds will be made from strong, impact-resistant materials and will be installed in a way that allows them to withstand the pressure of strong winds.

One common type of window that is designed to withstand high winds is the hurricane impact window. These windows are made from laminated safety glass, which is a type of glass that is composed of two or more layers of glass that are bonded together with a plastic interlayer. This glass is much stronger and more resistant to impact than regular glass, making it an ideal choice for use in windows that need to withstand high winds.

In addition to the materials used, the design of the window also plays a role in its ability to withstand high winds. Hurricane impact windows are typically installed using special mounting systems that allow the window to flex and move with the wind, rather than breaking or becoming dislodged. These mounting systems help to distribute the wind load evenly across the window, increasing its ability to withstand high winds.

It is difficult to provide an exact wind speed that a house window can withstand, as this will depend on the specific characteristics of the window. However, many hurricane impact windows are tested to withstand winds of up to 150 mph or higher, depending on the size and location of the window. In general, the stronger and more impact-resistant the materials and design of the window, the more wind it will be able to withstand.
