How To Insulate Windows for Winter

Did you know windows are the biggest cause of heat loss during wintertime?

When windows are not insulated properly, you can feel the cold breeze coming from them inside your cozy home. It can lead to great heat loss and will eventually interrupt your comfort.

So, what can be done? How can you trap the warmness and keep your home cozy during a wintry night without hurting your pocket?

To help you beat the cold and save energy, we have shared 8 ways to winter window insulation.

#1 Blinds and Curtains

The first method is to insulate the window using the best insulating blinds and curtains. Using these methods in combination is more beneficial.

Along with insulation, they also offer you the power to control the amount of sunlight entering your home.

Any kind of curtains can work, but the thermal window covering works the best. Such coverings create an effective layer of insulation and stop air movement. Likewise, you can search for the best blinds to keep cold out. 

#2 Weather Sealing Strips

You can apply temporary insulation like weather sealing clips to stop the heat loss through the movable parts of windows. Cut window insulation foam, felt stripping, or

EPDM into appropriate size. Apply them over the seams and gaps of the window to stop cold air.

Weather sealing strips are cheaply available to block cold air from windows. So, you can easily purchase as much as you want to keep your home warm. But you need to remove these seals to open your windows. It’s a removal of window insulation.  

#3 Caulk

Do you have cracks around the window or in the window sash? Don’t worry because it can be quickly insulated using winter-proof window caulk.

It’s an inexpensive window and door insulation method with easy application. The only drawback of using caulk is that you need to reapply it every year. That’s because changes in temperature cause the windows to expand and contract.

You can apply caulk on the outside of your windows for better exterior window insulation.

#4 Window Film

Window film is the best way to insulate windows to keep cold air out. You need to apply the transparent film on the inside of the window to act as a barrier. It keeps the cold air out and prevents heat loss, offering a cozy, relaxing atmosphere. 

Window film is an inexpensive and long-term window cover for winter that needs zero maintenance. Also, it does not affect the sunlight or the appearance of your window.

#5 Secondary Glazing

Are you looking for a long-term solution for insulating glass windows? If so, secondary glazing should be your choice. It’s a budget-friendly option, similar to window film.

Secondary glazing on the window creates a shield between windows and the interior of your home.

You might need to hire professionals to apply secondary glazing on your window. Like window film, secondary glazing allows you to slide open the window without removing the insulation.

Secondary glazing improves window insulation without influencing the level of sunlight entering your home.

#6 Double or Triple Glazing 

Double or triple glazing is similar to secondary glazing, only adding more insulation layers to your existing glass window. It’s an effective insulation method for insulating the front door and windows.

You need around three panes of glass for each frame so the cold air does not enter your home. As double or triple-glazing traps more air, they can insulate better.

The only limitation of double or triple-glazing insulation is its cost. Also, if you live in a rented apartment, you might not get permission to replace the usual single-glazed windows with double or triple glazing for sliding window insulation.
