Are you looking for ways to save on energy costs this winter? Weatherizing your windows can be an easy and effective way to save on energy bills while also improving your home’s insulation. In this blog post, we’ll show you how to weatherize your windows in five simple steps. From caulking and weatherstripping to installing plastic window insulation, there are several ways to keep your home warm and energy bills low. Read on to learn how to weatherize your windows and start saving money today!


When it comes to weatherizing your windows, there are a few products that can help. First, window film is a great way to make windows more energy efficient. Window film blocks out sunlight and reduces heat loss, making it a great choice for those looking to reduce their energy costs. Second, solar screens are another option. Solar screens are a type of exterior covering that acts as a barrier between the window and the elements, allowing you to control the amount of sunlight entering your home and reducing energy costs. Lastly, storm windows are an effective way to weatherize your windows. Storm windows are an extra layer of glass or plastic that fits over your existing windows, providing an additional layer of insulation and protection from the elements.


Weatherizing your windows is an important part of making sure your home stays warm and energy efficient. Here are some tips to help you weatherize your windows:

• Check for air leaks: Before doing any weatherizing, make sure to look for any drafts or air leaks around your windows. This can be done by feeling around the window frame and sealant for cold spots or using a lit incense stick to detect any moving air.

• Add insulation: Adding insulation around the window frame is one of the most effective ways to weatherize your windows. This can be done with foam strips, expandable foam sealant, or even weather stripping.

• Install window film: Window film is an inexpensive and easy way to add extra insulation to your windows. Window film works by blocking out UV rays, which can cause heat to escape from the inside of your home.

• Install solar screens: Solar screens are a great way to keep your home cool in the summer and warm in the winter. Solar screens are specially designed to block out sunlight during the hot months and trap heat in during the cold months.

• Consider storm windows: Storm windows are a great way to add an extra layer of insulation to your windows. Storm windows can help keep cold air out and hot air in, as well as reduce condensation on the windows.

How to Weatherize Your Windows in 5 Steps

Inspect your windows

Before you begin weatherizing your windows, it is important to inspect them for any existing damage. This includes checking for cracks in the window frame, broken glass, and other signs of wear and tear. If you find any issues, make sure to fix these before continuing with the weatherization process. Additionally, check the seals around your windows to make sure they are still intact. If they are not, replace them as needed. Weatherizing your windows should include a thorough inspection to ensure that everything is in good condition.

Caulking and weatherstripping

Caulking and weatherstripping

Caulking and weatherstripping are two of the best ways to weatherize your windows. Caulking is a process in which a sealant is applied along the edges of a window frame to create a tight, airtight seal. This helps keep cold air out and warm air in during the winter months. Weatherstripping involves installing a type of material along the edge of the window, such as rubber or vinyl, to create a similar seal. This helps keep out drafts and improve energy efficiency. Both caulking and weatherstripping are relatively easy to do and can be done with materials that you can find at any hardware store.

Add window film

Add window film

Adding window film is a great way to weatherize your windows. Window film provides an extra layer of insulation to keep the cold out and the heat in. It also helps to reduce glare, giving you better visibility and protecting your furniture from fading. Window film also blocks UV rays, reducing your energy bills and protecting your skin from harmful radiation. To install window film, simply measure the window, cut the film to size, and adhere it to the glass using a spray adhesive or double-sided tape. Be sure to remove any bubbles or wrinkles in the film for a smooth finish. Window film is an affordable and easy way to weatherize your windows and save money on energy bills.

Install solar screens

Install solar screens

Solar screens are an effective way to weatherize your windows and keep the hot summer sun from entering your home. Solar screens work by blocking direct sunlight from entering the window, while still allowing indirect light to come in. Installing solar screens is relatively easy and should take about an hour for most windows.

First, measure the window frame to determine the size of the solar screen you will need. Once you have determined the size, purchase the appropriate-sized solar screen material and pre-cut it into the desired shape. Next, attach the solar screen material to the window frame using adhesive tape or screws and washers. Finally, once the screen is in place, check that it is secure and covers all areas of the window.

With solar screens in place, you can now enjoy a cooler house during the summer months and feel confident that you have successfully weatherized your windows.

Consider storm windows

One of the best ways to weatherize your windows is to install storm windows. Storm windows are an extra layer of protection that can help keep your home warm in winter and cool in summer. They are easy to install and can make a big difference in reducing energy loss from your windows. Storm windows are available in a variety of styles and materials, such as aluminum, vinyl, or wood. Some also come with low-E coatings that help further reduce heat loss. Installing storm windows is an affordable way to help seal up air leaks around your windows and reduce your energy bills.


Weatherizing your windows can make a huge difference in the comfort of your home and help you save money on energy costs. By taking the time to inspect, add window film, install solar screens, and consider storm windows, you can weatherize your windows for maximum energy efficiency. With a little effort and dedication, you can make sure that your home is comfortable, energy efficient, and cost-effective.

Q. Is there anything I can do to prevent heat or cool air loss through my windows?

A. Yes, there are a few things you can do to help weatherize your windows and save energy. First, replace or repair any damaged or broken window panes. If your windows are single-pane, you may want to consider investing in double- or triple-paned windows, as they provide better insulation against the elements. Second, install insulated window shades or blinds that are designed to keep hot and cold air out of the house. Third, use caulk or weatherstripping around the edges of your windows, ensuring a tight seal and protection from drafts. Fourth, install storm windows on the outside of existing windows for added insulation and noise reduction. Finally, adding plastic window film is a great way to reduce heat loss through the windows. These are just a few ways you can weatherize your windows and keep your home energy efficient year-round!

Q. How often should I check if my windows need to be weatherized?

A. It’s recommended that you inspect your windows twice a year (in both spring and fall) for any signs of wear and tear such as missing caulk or cracks in the glass. Additionally, inspect the window frames and trim for areas where air could be leaking in or out. If you notice any wear or damage, it’s important to take action right away before more serious issues arise. Also, take note if you start feeling cooler or warmer air than usual coming through your windows – this could be an indication that it’s time to re-weatherize your windows. And don’t forget to clean off all dirt, dust, pollen, and debris which can accumulate over time and lead to insulation issues. Taking these steps will ensure your windows remain properly sealed and free from drafts year round!

Q. Are there other benefits to weatherizing my windows aside from saving energy?

A. Absolutely! Properly weatherizing your windows can make them much quieter and improve the overall comfort level in your home. In addition, installing quality materials such as double-paned windows or insulated shades can help reduce outside noises like traffic and barking dogs. Plus, updating older windows with modern technology helps improve their durability so they last longer and require less maintenance over time. By taking steps to weatherize your windows now, you’ll enjoy increased comfort levels, lower utility bills, improved soundproofing, and peace of mind for years to come!
