Yes, plastic film or window insulation film can be an effective and cost-efficient way to improve the energy efficiency of windows, particularly in colder climates.
Here’s how plastic film over windows works and its benefits…
- Insulation – Plastic film creates a barrier between the interior of your home and the cold air outside, reducing heat loss through windows. This helps to keep your home warmer in the winter and can result in energy savings by reducing the need for heating.
- Draft Reduction – By sealing gaps and cracks around windows, plastic film can help prevent drafts from entering your home, increasing comfort and reducing cold spots near windows.
- Condensation Control – Plastic film can also help reduce condensation on windows by creating a warmer surface temperature, which can help prevent moisture buildup and potential damage to window frames and surrounding surfaces.
- Affordability – Window insulation film is relatively inexpensive compared to other energy-saving measures such as window replacement or installation of storm windows. It’s a cost-effective way to improve the energy efficiency of your home, particularly for older or single-pane windows.
- Easy Installation – Most window insulation film kits come with all the necessary materials and instructions for easy installation. The film is typically applied using double-sided tape and then heated with a hairdryer to shrink and seal it in place.
While plastic film over windows can be effective in improving energy efficiency and reducing drafts, it’s essential to choose a high-quality film and ensure proper installation for optimal results. Plastic film may obstruct the view through windows and can degrade over time, requiring replacement periodically. For a more permanent and aesthetically pleasing solution, you may also consider upgrading to energy-efficient windows or installing additional insulation around windows.
