The Cost Of Window Plastic: How Much Does It Really Cost?

Plastic window insulation is an affordable way to reduce heat loss in your home. It's particularly useful if you live in an old, draughty house. You can buy a kit to insulate two windows for as little as $5, and it's estimated that this could save you $190 in energy costs. However, some people argue that plastic window insulation is ineffective at reducing drafts and energy costs.

Plastic window insulation film kit prices

Using plastic film insulation on your windows can result in significant savings on energy costs. A single layer of window film can reduce heat loss by 33% for windows only, or about 14% for the whole house. For a "vintage" house with single-pane windows and 4" stud walls, window film can result in a 50% saving for windows only and a whole-house saving of 29%. During the heating season, using plastic film insulation on your windows can result in average savings of over $15 per window.

Plastic window insulation savings

Plastic window insulation is an affordable way to reduce heat loss and save on energy costs. A typical kit costs around $5 and can be used on two windows, depending on their size.

Using plastic film insulation on your windows can result in significant savings, especially if you live in an older, drafty house. On average, you can expect to save over $15 per window during the heating season.

For example, if you have a kit that covers two windows, you can expect to save around $30. This is a considerable return on your investment, especially when compared to the cost of replacing windows.

Additionally, plastic window insulation can also help reduce heat gain during the summer months, leading to further savings on cooling costs. If you have windows that don't open, keeping them insulated year-round can provide additional savings on your energy bills.

It's important to note that the effectiveness of plastic window insulation may vary depending on the type of windows you have. For example, adding a single layer of window film to double-pane windows can result in a 33% reduction in heat loss for the windows only or about a 14% reduction for the whole house. On the other hand, if you have "vintage" single-pane windows, the same window film can provide a 50% saving for windows only and a whole-house saving of 29%.

Plastic window insulation for single-pane windows

Plastic window insulation is an affordable way to insulate single-pane windows. A typical kit costs $5 and is good for two windows, depending on the size. It can save you up to $190 in energy costs or $18 per window.

The plastic film is very thin, so it's not suitable for outdoor applications. However, it can provide significant savings on your heating and cooling costs, especially if you live in an old, drafty house. For example, adding a single layer of window film to a single-pane window can increase its R-value from R0.9 to R2.0, resulting in a 50% reduction in heat loss for the windows and a 29% reduction for the whole house.

You can find window insulation kits at various retailers, such as Walmart, with prices starting as low as $3.48. These kits typically include rolled insulation film that you can cut to fit your windows. The film is transparent, allowing natural light to enter while providing insulation against the cold.

Overall, plastic window insulation for single-pane windows is a cost-effective solution to improve the energy efficiency of your home, particularly during the heating season.
