A good home should protect you from the outside weather conditions. After all, the main purpose of a house or building is to shelter.

It’s easy enough to keep out weather conditions such as rain or wind or sun, but keeping out the temperature is another matter.

Whether it’s too cold or too warm, you want to be able to keep the outside temperature separate from the one you set up indoors.

But buildings have a weak spot: windows. 

During winter, the cold seeps in, and during summer it’s the heat. Insulating your windows is very important, and it will save you from having to replace the windows when each different season comes around.

It’s quite common to insulate for the winter, but how exactly does one insulate windows for the summer?  The aim: to keep you home fresh and cool, safe from the deadly heat of the toughest of summers.

For the solution, there are plenty of different ways, and most of them don’t require too much effort or cost.

In fact, most of these ways can be considered DIY’s of insulation, as they’re easy to do, budget-friendly, and offer a fast solution!

Best Way to Insulate Windows for Summer

Best ways to insulate windows for summer

Insulating your windows for summer can be a life-saver when the heat becomes unbearable, and it’s the fastest and easiest way to keep your home cool and fresh inside.

We’ve compiled a few of the most popular ways to insulate your windows for summer, with some step by step guides for great results! 

  • Bubble wrap:

Bubble wrap is an extremely simple and fast way to insulate your windows for summer.

It’s also very cheap and can work on any window, no matter the shape or size, as you can cut the perfect piece of bubble wrap for it. 

    • Cut a piece of bubble wrap that fits the size and shape of your windowpane. This should be fairly easy to do.
    • Use a spray bottle to spray a layer of water onto the window.
    • While the window is still wet, place the bubble wrap onto the window, with the bubble side of the wrap facing the glass of the window.  
    • Make sure that the bubble wrap covers the window completely. Then press the bubble wrap into place. The thin layer of water will allow the bubble wrap to adhere to the window, staying put. 
    • To remove it, simply pull from one of the corners. It doesn’t harm or stain the windows, and the bubble wrap can be used over and over again for as long as you want!

 

  • Weather-stripping:

This is used to seal out the air that is leaking in through the window, be it warm or cold, so it can also be used for the winter as well as for the summer.

It can be done with different types of materials so that you can choose the one most suitable for your window. Weatherstripping can be done with nail-on strips or with self-stick tapes (with the second form being the easiest and fastest to use). 

It requires a bit more research, as you need to know which type of weatherstripping is most suitable for your window, and you then need to apply it properly so that the air leak is effectively sealed. 

  • Reflective film:

This is an option very similar to the bubble wrap, but using a reflective film instead which helps keep the heat out.

The reflective film can be bought for a very budget-friendly price and is very easy to install. It will also look a lot better than the bubble wrap! 

    • Get the reflective film and cut out a piece that will fit the window by covering it completely. This means it is apt for any size or shape, which is very convenient!
    • Before installing the reflective film, it is very important that you thoroughly clean the window. Any dirt from the window will stick out under the reflective film, as it is a very thin layer. 
    • Using a spray bottle, spray a solution of water and shampoo onto the window. Adding a drop of two of shampoo, rather than using just water, allows the window to be a lot more slippery when applying the reflective film so that it doesn’t stick too fast and you have time to smooth out any bubbles from under it. 
    • Carefully place the reflective film on the window, pressing down and smoothing out any bubbles so that it is completely flat on the window surface. 
    • Let it bond for around 30 days, during which you shouldn’t try to clean the window with the reflective film. Once it has bonded, it will have perfectly adhered and you will barely even notice it is there, as you can perfectly see out of the window. 

 

  • Cellular shades:

Cellular shades are a very popular option, and many homes that are located in hot climates have them permanently installed.

They can look very pretty and decorative, and they’re very efficient at keeping out the heat, as well as blocking and filtering the light so that the harsh sunlight isn’t streaming directly into the room. 

They are very easy to install and can be bought to fit and suit your window thanks to the numerous options available. 

  • Energy-efficient windows:

There are many DIY methods for insulating your windows for summer, to efficiently keep out the heat and keep your home cool.

However, if you want a more permanent solution that is 100% guaranteed to work, you might want to upgrade your windows to be energy-efficient.

These will usually require a professional installation, but it will be more than worth it long-term!

Conclusion

Summers can be just as harsh as winters, and windows can be the weakness of a home, as the heat can often seep through them and elevate the temperature within the house.

In order to keep your house cool and fresh, and keep out the heat of summer, you can insulate the windows.

There are many different ways to insulate your windows, with most ways also being extremely easy and affordable.

From using bubble wrap to installing a reflective film, or even adding weatherstripping. There are many easy solutions for keeping out the summer weather.

And if you want more permanent insulation, you could install cellular shading or even upgrade your windows so that they’re energy-efficient.
