## Can the wind break a Windows?

## What can cause a car window to shatter?

Any damage to auto glass can lead to more damage in several ways. Very cold temperatures can cause a crack to in your auto glass to contract. The pressure from that contraction can lead to further damage. Contraction can also cause the glass to shatter, but that’s an extreme case.

## What wind speed can windows withstand?

A Design Pressure or DP rating measures the strength of a window. Standard residential windows have DP values between 15 and 50. A DP 15 window can reasonably be expected to sustain winds of roughly 77 mph before shattering. A DP 50 window is expected to sustain winds up to 173 mph.

## Can 70 mph winds move a cars?

According to the engineers that helped devise the Enhanced Fujita Scale, winds of between 111 – 135 m.p.h. are enough to lift and move average sized cars.

## How fast does wind need to be to knock someone over?

This happens so much that scientists have given this phenomenon a name. They call it spontaneous glass breakage.

## Can a window crack by itself?

The short answer is: not really. Stress cracks are a naturally occurring result of expanding and contracting glass due to temperature changes. However, installing thicker glass and choosing glass features based on your climate and sun exposure needs may help decrease your risk.

## What wind speeds are dangerous?

“Damaging high wind” with sustained speeds greater than 58 mph, or frequent wind gusts greater than 58 mph. Damaging wind conditions are consistent with a high wind warning. “A High Threat to Life and Property from High Wind.” “High wind” with sustained speeds of 40 to 57 mph.

## What is gale force wind speed?

The U.S. National Weather Service defines a gale as 34–47 knots (63–87 km/h, 17.5–24.2 m/s or 39–54 miles/hour) of sustained surface winds. Forecasters typically issue gale warnings when winds of this strength are expected.
