Condensation and frost on the inside of windows occur when warm, humid air inside comes in contact with a pane of glass chilled by the outside air, according to the American Society of Home Inspectors. This reduces the temperature of the air in contact with the glass, forcing condensation of moisture. If the outside temperature is cold enough, this moisture can freeze on the glass and create interior frost.Continue Reading
A number of factors can contribute to window frost. Single-pane glass or poorly insulated windows can allow interior heat to escape, chilling the interior surface of the glass panes. High humidity levels in the home can allow extra moisture to condense on these cold surfaces, contributing to window frost.
Removing excess moisture with exhaust fans or a dehumidifier can help reduce interior frost, as can keeping blinds or curtains open and allowing air to circulate across the surface of the glass. This prevents the air at the window from becoming too cold, thus reducing the chance of condensation and frost. Increasing the heat inside the home can also help dry out the air as well as keeping warm air circulating against the windows, which prevents the glass from becoming cold enough to form frost.Learn more about Weather & Tides
The average dates when frost ends in Kentucky range from mid-April to mid-May as of 2015. There still may be a small chance that frost can occur outside of these dates. The predicted last frost dates vary by region in Kentucky, but are usually around this time frame.Full Answer >
Frost is formed on the inside of a window, when the air on the outside of the glass is cold enough to cause the interior water vapor to condense and freeze against the sufficiently cold inside surface of the glass. This is no longer a common occurrence, because most homes now have double-pane windows that are much better thermal insulators. Older glass windows, however, could produce elaborate interior frost patterns because the ice crystals would form around scratches, streaks or other imperfections on the interior glass surface.Full Answer >
To find a suitable home or shelter to relinquish an unwanted or untenable pet, contact the local animal control or the local branch of the Humane Society or the American Society for the Prevention of Cruelty to Animals. They will provide resources and localized advice to aid through relinquishment.Full Answer >
Weather patterns move from west to east due to the jet stream, which is a fast flowing air current found at an altitude of about 9 1/2 miles above the Earth's surface. This phenomenon occurs due to factors, such as the Earth's rotation and the difference in temperature between two air masses.Full Answer >
