Cold Weather Tip: Insulating your windows during cold weather

Windows provide our homes with light, warmth, and ventilation, but they can also negatively impact a home’s energy efficiency. You can reduce energy costs by installing energy-efficient windows in your home. If your budget is tight, energy efficiency improvements to existing windows can also help.

You can improve the energy efficiency of existing windows by adding storm windows, caulking and weatherstripping, and using window treatments or coverings.

Adding storm windows can reduce air leakage and improve comfort. Caulking and weatherstripping can reduce air leakage around windows. Use caulk for stationary cracks, gaps, or joints less than one-quarter-inch wide, and weatherstripping for building components that move, such as doors and operable windows. Window treatments or coverings can reduce heat loss in the winter and heat gain in the summer. Most window treatments, however, aren’t effective at reducing air leakage or infiltration.

Bubble Wrap

Use bubble wrap on windows when cold weather hits fast and there’s no time to get storm windows installed.

This is a simple technique for insulating windows with bubble wrap packing material. Bubble wrap is often used to insulate greenhouse windows in the winter, but it also seems to work fine for windows in the house. You can use it with or without regular or insulating window shades. It also works for windows of irregular shape, which can be difficult to find insulating shades for.

The view through the bubble wrapped window is fuzzy, so don’t use it on windows where you need a clear view. But, it does let plenty of light through.

You can always call us to help you with new insulated windows or storm shutters, after the storm has passed or as a preemptive measure before the winter storms come.
