DIY and Low-Cost Windows and Doors Insulation Options

Keeping the frost out and the heat in is essential in a cold climate. Ideally, energy-efficient windows and airtight storm doors would be the best choice, but this isn’t always feasible. It isn’t the case in our beautiful 1940s character house. For immediate, temporary solutions, many DIY and low-cost insulation options for windows and doors can make a significant difference.

Why Consider DIY and Low-Cost Insulation Options?

While these DIY and low-cost solutions might not measure up to high-efficiency alternatives, they can still be remarkably effective. Instead of dealing with a drafty window, you could end up with just a chilly window. Some of these low-cost methods work surprisingly well, helping you save on heating costs and keeping your space warmer.

Remember, every bit of frost you can keep out means less heating required, which ultimately saves you money and keeps your feet and plants warmer. Simple installations can be a worthwhile effort. Let’s explore them.

Door Sweeps and Draft Stoppers

When we first moved into our house in late November, there was little time for significant improvements. To combat the draft from the old door, I used a pillow against it, though a draft snake would have been a more aesthetically pleasing option. Unfortunately, the pillow froze to the door! We quickly realized that replacing the door was a priority. Later, the old door became a chicken coop door; well, that was a better use.

Installing a door sweep at the bottom of exterior doors will seal the gap between the door and the threshold. A draft stopper, or “door snake,” can be placed at the base of doors or windows for a simple, effective seal.

Heavy Curtains

Curtains designed to block drafts can make a huge difference. I especially appreciate heavy curtains because you can close them at night for insulation while still allowing sunlight to filter in during the day. Please be sure to look for thermal curtains designed to keep heat in. Often they also keep light out and look good, contributing to a cosy interior design.

Weatherstripping

Applying foam, rubber, or vinyl weatherstripping to the edges of windows and doors can effectively seal gaps where sashes and frames meet. This simple addition significantly reduces drafts.

Window Insulation Film

Installing a window insulation film is another excellent option. It is my favorite for indoor window insulation. Installed correctly, you will not be able to tell there is a film layer.

Use a plastic film kit over your window frame, leaving a small gap, and then use a hairdryer to shrink it tight, creating an insulating air pocket. This film can be applied both inside and outside for double protection.

Bubble Wrap

Using bubble wrap is similar to the insulation film, but it does prevent outdoor visibility. If you’re not concerned about seeing outside, taping bubble wrap to your window glass lets natural light in while providing insulation. To install, lightly spray the glass and press the bubble wrap against it to help it adhere and create an insulating barrier. It is an excellent option for basement windows.

An additional tip is to build a wooden frame with either bubble wrap or insulation film attached, and then screw the frame to the window opening. It makes for easy reuse and quick application for smaller windows.

Styrofoam

While Styrofoam isn’t suitable for indoor living spaces where people spend time, it works exceptionally well in growing rooms or uninhabited spaces. Its insulating properties can significantly reduce heat loss. We use it for the growing room sliding door during the months when the door is not used, but lets in too much cold.

By implementing these DIY, low-cost insulation methods, you can effectively combat winter chill and enjoy a cozier, more energy-efficient home without breaking the bank. Every minor enhancement contributes to a warmer environment and lower heating costs!
