Does Plastic On Windows Reduce Heat Costs?

Plastic window insulation is a cost-effective way to reduce heat loss in your home. It's a great option for those who can't afford to replace old, draughty windows, and it's said to save you between 10% and 33% on heating costs.

Plastic window insulation can save you 10-30% on heating costs

If you have old, draughty windows, you can either replace them or seal them with insulating window film (a.k.a. plastic wrap). The latter option is much cheaper and, according to Energy Star, can cut your utility bills by up to 20%.

However, the impact of plastic window insulation is hard to measure. One source says that, in their 1921 home with single-pane windows, the effect of the plastic could not be measured in terms of utility bills.

Another source says that, while plastic window insulation can save you money in the winter, it won't make much difference in the summer. They recommend weatherstripping for the summer, as natural cooling can save a lot of money.

It's a good alternative to replacing old, draughty windows

However, it's important to note that the impact of plastic window insulation on utility bills can vary depending on the type of windows you have. For example, in a home with single-pane windows, the impact of the plastic may not be as significant in terms of reducing utility bills. On the other hand, in a new two-storey home with double-pane windows and 6" stud walls, adding a single layer of window film can result in a 33% reduction in heat loss through the windows, or about 14% on the whole house.

Additionally, sealing up leaks throughout your house with plastic window insulation can further contribute to reducing your utility bills by up to 20%, according to Energy Star. This means that the effectiveness of plastic window insulation in cutting heat costs depends on a variety of factors, including the type of windows, the climate, and the overall energy efficiency of your home.

Overall, while plastic window insulation may not be a perfect solution for every home, it can be a good alternative to replacing old windows, especially if you're looking for a cost-effective way to improve your home's energy efficiency and comfort during the winter months.

It's most effective in the winter

Plastic window insulation is most effective in the winter. It's reasonably good at trapping heat, and can save you 10-30% on heating costs. Energy Star, a government program launched by the Environmental Protection Agency (EPA), agrees that sealing up leaks throughout the house with plastic can cut your utility bills by up to 20%.

However, it's worth noting that the impact of plastic window insulation may vary depending on the type of windows you have. For example, in a home with single-pane windows, the reduction in heat loss may not be as significant. On the other hand, 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 14% for the whole house.

Additionally, while plastic window insulation can be beneficial in the winter, it may not be as effective in the summer. In warmer months, natural cooling methods, such as opening windows or using thermal curtains, can be more efficient at keeping your home comfortable and reducing energy costs.

It's not as effective as thermal curtains

Plastic on windows can reduce heat loss and cut utility bills, but it is not as effective as thermal curtains. While plastic window insulation can save you 10% to 30% on heating costs, thermal curtains can provide a higher level of window insulation.

Plastic window insulation works by trapping heat. Depending on where you live, sealing up leaks throughout your house with plastic can cut your utility bills by up to 20%. However, the impact of plastic window insulation may be hard to measure. One user with single-pane windows from 1921 found that the effect of the plastic could not be seen in their utility bills.

Thermal curtains, on the other hand, can provide better insulation. In addition to reducing heat loss, they can also keep your home cooler in the summer. By using thermal curtains to block out the sun during the day and opening the windows at night, you can maintain a comfortable temperature in your home without the need for air conditioning.

If you are looking for a cost-effective way to reduce your heating bills, thermal curtains may be a better option than plastic window insulation. They provide better insulation and can also help keep your home cooler in the summer.

It's not a good look

While it's true that plastic window insulation can reduce heat loss and lower your utility bills, it's not the most attractive solution. The plastic wrap may be effective, but it can also be unsightly, especially if you have multiple windows or large panes of glass.

If you're looking to improve the energy efficiency of your home, there are other options that can be more aesthetically pleasing. Thermal curtains, for example, can provide a higher level of window insulation than shrink-wrapping your windows. They can help keep the heat in during the winter and block out the sun's warmth in the summer, all while adding a touch of style to your home.

So, if you're concerned about both function and fashion, you may want to consider alternatives to plastic window insulation. While it may save you money, it's not going to make your home look its best.
