If you're looking for easy and affordable ways to avert drafts and keep your home cozy, you're probably familiar with window insulation.

And, for the job, there's no product more recommended and easy to use than the number one bestselling Duck Brand Window Insulation Kit, available at Amazon.

Here, we explain why it's one of the best ways to weatherproof your windows.

This Window Insulation Is the Best Way to Cover Windows for Winter

All prices were correct at the time of publication.

Using window insulation kits is a DIY draft-proofing solution we recommend time and time again, and one product crops up as recommended by pros more than all the others: the Duck Brand Window Insulation Kit, available at Amazon, and it's easy to see why.

For starters, using it is one of the simplest ways to prevent the sneaky ways drafts hide in your home, and one of the quickest, most affordable ways to insulate windows and tick off this all-important maintenance task to help lower your energy bills.

One box of shrink-to-fit window film can insulate up to ten standard-sized 3' x 5' windows, and there's no measuring required – simply cut to size and use a hairdryer to shrink the film, get rid of wrinkles, and increase the transparency.

You'll just need to clean your windows and let them dry completely before applying the film. We recommend doing so with a damp duster, available at Walmart, before following up with the Method Glass Cleaner + Surface Cleaner, also available at Walmart, paired with a microfiber cleaning cloth from Amazon.

Additionally, this insulation kit isn't only suitable for glass windows. You can also use it on painted or finished wood, aluminum, or vinyl, to help cut energy bills all around the home.

And, once the winter season is over, the window kit removes easily. Therefore, it won't ruin your window treatment ideas come spring and summer, either.

Therefore, it's no surprise that over 10,000 shoppers bought it last month alone, or that it boasts over 3,200 five-star reviews, firmly answering the question of 'Do window insulation kits work?'

'Amazing product for an amazing price,' reads one recent review from Wendy. 'Our windows are old and extremely drafty. You could literally feel the draft hitting you while sitting on the couch. Our heater would run pretty much consistently, and that made for a pretty hefty electric bill.

'My brother-in-law suggested this product [that] was so easy to install and works perfectly. Our living room actually stays warm now, our heater isn’t running constantly, and no more draft.'

A second reviewer, John, writes that it's an 'excellent product with superior results. This product, by far, is the best window covering on the market. Crystal clear, and installation is straightforward and effortless. The tape supplied is premium quality and removes easily.

'The "shrink factor" of the plastic is great and tightens up, providing no wrinkles. One tip: Make sure you keep the hair dryer at least four or six inches from the plastic when shrinking.

'Work from the top down, getting rid of wrinkles as you proceed.'

Therefore, it's easy to see why this window insulation kit is one of the best ways to keep your home warm without turning up the heat, and easiest ways to keep a poorly insulated house warm without spending big.
