Storm Windows: Save Money and Lower A/C Costs
The argument for screens and storm windows is simple. The heat losses can be reduced by up to 50% if you take the help of better insulation of your home as per the US department of Energy.

Storm windows are an additional layer of windows. They reduce the circulation of air out of your windows. They offer an additional barrier that shut out wind and cold in winter and high temperatures in summer.


Screens: Reduce Pollutants
The EPA states that in the average home, levels of pollutants are 2 to 5 times higher than outdoors. Opening your windows once a day when the temperature is comfortable can rid the home of those pollutants. Screens make this efficient and allow the air flow, but keep out unwanted materials and bugs.
