Window Insulation – Key to HVAC Efficiency in Your Home

Cracks and gaps around windows are the main culprits when it comes to compromising your ideal home climate. Window insulation can help minimize the transfer of heat, and it can also prevent energy wastage.

Insulating your windows is a simple process that can be done in a few hours. Follow this guide to learn more about how to insulate your windows this summer and save money on your energy costs all year long.

Sealing Your Windows

In order to ensure that the air in your home remains constant throughout winter and summer, it is essential that all windows and doors are properly sealed. There are several easy DIY methods for doing this.

Many window insulation kits come with plastic film that is applied to the frame of your windows and sealed with double-sided tape. These products can be found for very reasonable prices online and in stores. When choosing a kit, be sure to assess the number of windows that need to be covered and their dimensions. Also, look for a kit that can be used more than once, as thicker films are often reused.

A more permanent solution is to use caulking to fill any gaps in your windows and frames. You can use the same technique to seal cracks around door frames as well. The best window caulk will be flexible and last year-round. It is recommended that you wear a dust mask when applying any caulking.

Insulating Your Windows

Window insulation can help ensure that the temperature of your home stays consistent from room to room. Without it, cold air seeps in and warm air escapes, causing your heating system to work overtime and leading to higher energy bills. Insulating your windows can help to reduce energy bills, improve comfort, and protect your windows from damage.

Newer windows have insulated glass that helps prevent energy loss. They have two or more panes and a space in between that manufacturers fill with either air or argon gas. This argon, which is colorless and odorless, acts as an excellent insulator.

For older or budget-conscious homes, there are several simple ways to get a similar effect from the DIY route: Apply weatherstripping around the edges of your windows to seal cracks and prevent drafts. You can also use caulking to fill in cracks around the frame and create a tighter seal. Window film is another option that can reduce heat transfer and ultraviolet ray penetration while protecting your windows from damage.

Installing Insulation Film

Installing window insulation film is one of the most popular options for lowering energy costs and improving comfort without replacing the windows. It’s simple and relatively inexpensive.

You can find window insulation kits at most hardware stores, but you’ll also need a hair dryer, a tape measure and scissors. Before applying the tape, clean the molding around your windows, including the sill and frame. Open any blinds, if applicable, to make the job easier and allow it to dry completely before you proceed.

The window insulation film works by reflecting the sun’s infrared radiation away from the interior, preventing it from absorbing and heating your space. It also reduces glare, making it much easier to work or watch TV comfortably without straining your eyes. While it won’t offer the same energy savings as new low-E double-pane windows, you will still see significant reductions in your energy bill and comfort level.

Installing Weather Stripping

Adding weather stripping to seal the gap between a window and frame is one of the quickest and least expensive ways to reduce drafts. However, the material can wear out over time and may need to be replaced periodically.

Installing a window insulation kit is another low-cost and fast way to seal drafts. Choose a kit that is designed to fit the dimensions of your windows and read instructions carefully before starting. Clean your windows and frames before applying double-sided tape and plastic film, if needed. Most kits use a hair dryer to shrink the plastic and make a tight seal.

Insulation is a great long-term investment in your home and can improve the comfort of rooms while keeping your energy bills down. However, if you want the ultimate in efficiency, replace your windows with new double pane units featuring argon gas or a Low-E glass package. The second pane effectively blocks any unwanted thermal energy from passing through, which is a problem with single-pane windows that tend to absorb and radiate heat in summer or lose indoor warmth in winter.
