Window insulation kits are popular, cheap, and effective for most. That said, a little controversy surrounds the effectiveness of insulation film. 

Some shun plastic window insulation kits because of how they look. For others, shrink-wrapping a window’s open areas may be a shoddy DIY solution to a serious problem.

The Truth About Window Insulation Film

Window insulation kits use window insulation film. The film is a low-cost insulation solution used to reduce and terminate drafts. It consists of clear, oversized plastic that fits over a window’s interior. 

Normally, window insulation kits offer double-sided tape to help the homeowner adhere the plastic sheets to the frame. Once secured, the plastic is “shrunk” to fit and adhere to a window. 

To shrink window insulation film, one only needs to hit it with a hair dryer or a similar heat source. Once the window is sealed, it’s insulated.

Does Insulation Film Work?

Despite the controversy surrounding DIY homeowner solutions, both window companies and repair gurus consider insulation film to be effective. It really works, and it can increase a window’s insulation for many months.

Some of the benefits of window insulation kits include..

Energy Savings

Window insulation kits can help save energy by reducing drafts and preventing heat from escaping through windows, particularly if you have older or single-pane windows. By reducing drafts and improving insulation, these kits can lower your heating costs during the winter and reduce the workload on your heating system.

Affordability

These kits are a low-cost solution to replacing windows or installing more permanent insulation. They usually cost around $10 to $30 per window or a full kit for multiple windows. 

Easy Installation

Window kits are DIY-friendly, making them easy to install. They are accessible for homeowners who need to add a layer of insulation to their home without professional help and without a long-term commitment. 

Temporary & Removable

Kits are temporary and can be removed once the weather improves, making them a flexible solution for those who want a seasonal upgrade without committing to brand-new windows. 

Allows Sunlight Through

Additionally, the insulation film lets in sunlight, which can warm a window further. This side benefit is commonly overlooked, but it’s incredibly valuable. Any natural heat gain is beneficial—reducing a heating system’s work throughout the day. Commonly used as an alternative to insulating curtains, insulation film retains natural heating elements while blocking out cold air.

Why All the Fuss?

Some homeowners reject DIY solutions altogether, considering window replacement to be the be-all and end-all of insulation problems. While window replacement does solve most problems, homeowners may not have the budget. 

A window’s ability to insulate is dictated by its R-value. A lower R-value indicates better insulation. Window insulation kits can improve a window’s R-value, adding comfort to a household. That said, improving a window's R-value isn’t always cheap, and window insulation kits today are one of the cheapest ways to do so.

A lot of homeowners reject window insulation kits due to sheer looks, too. Insulation film doesn’t look flattering and can even be off-putting in some scenarios. That said, it can be expensive to replace a window in general. The plastic film certainly increases insulation while addressing air leakage, all without costing a fortune to implement.

Should You Get Window Insulation Film? 

At the end of the day, you should do what your household needs. While insulation film adequately increases a home’s ability to retain heat, it is not a permanent solution. Sometimes, window replacement is the only answer to critical heat loss.
