When the cold weather picks up, you don’t need to automatically dial up the thermostat to stay comfortable. One simple way to keep you warm while saving money over the winter is to use a window insulation kit. These kits provide an extra layer of protection against the elements. They’re usually used once and then discarded, but they can be kept on for multiple seasons (fall, spring and summer) if desired.

The weatherizing process is simple. The film consists of thin polyester that adheres to the side of your windows; then you shrink-wrap it with a hair dryer for a firm fit. Clear film won’t obstruct your view while it blocks out cold air, and you can trim off excess film for a cleaner look.

Properly sealed homes are the most energy efficient and can reduce costs by hundreds of dollars. You can pick up window insulation kits at your local hardware store or order one of the highly-rated window insulation kits that are available on Amazon.

Amazon user Spencer echoed the enthusiasm, saying he’s used this product for two winters and said they make a bigger difference than you might realize.

“So if you have a few windows that seem to let in that winter cold, these will do the trick,” the reviewer said. “They are easy to install, stay well and are easy to remove come spring when you want to open the windows and let a breeze in.”

Meanwhile, reviewer Allfluksd said they were amazed with how well these worked.

“Before we would feel a cold ‘draft’ (not sure it was cold air blowing through or just colder because the windows are so bad) next to the windows,” the Amazon user explained. “This significantly cut down on that — there was a noticeable temperature difference using the plastic sheets. Because of this, it also reduced the amount of condensation we saw and although there was still some water on the bottom of the plastic film, there was nowhere near the amount we saw without it. ”

Are your windows drafty? If so, you can benefit from a little DIY weatherproofing. You can’t go wrong with a window insulation kit!
