10 Best Plastic For Windows 2025 in the United States

The Frost King V73/9H Indoor Shrink Window Kit is made from clear plastic, making it suitable for those wanting a transparent barrier on their windows. It is designed primarily for indoor use and offers good insulation, helping to keep out cold drafts and improving energy efficiency.

The plastic material itself is fairly durable, although the adhesive tape may need annual replacement due to wear from sunlight and normal stress. This kit is easy to install and use, which is a significant advantage for those unfamiliar with DIY projects. However, it must be removed if you wish to open your windows in warmer months, which can be seen as a drawback for some users.

Another downside is the potential need for seasonal reapplication to ensure a proper seal, indicating a bit of maintenance is needed. Aesthetically, its clear plastic design is unobtrusive, blending well with most window styles. In terms of sound insulation, it offers moderate reduction, making it slightly beneficial for quieter indoor environments. This product is best suited for individuals looking for an easy-to-use, temporary window insulation solution with clear aesthetics and moderate maintenance.

The Duck Brand Indoor 5-Window Shrink Film Insulator Kit is a practical solution for improving window insulation, especially during colder months. Made from crystal clear plastic, this kit provides a transparent and clean appearance that won't obstruct your view. One of its significant benefits is the reduction in energy costs by sealing out drafts and cold air, enhancing both energy efficiency and comfort in your home.

The kit includes enough film to cover five 3' x 5' windows, and the film is designed to be heat-shrunk, ensuring a tight seal. The installation process is straightforward, thanks to the included double-sided tape and the rolled film design introduced in the 2023 model. However, the product lacks ultraviolet light protection, which might be a downside for those concerned about UV damage to interior furnishings.

Durability-wise, the plastic material used is generally sturdy, although it may require careful handling during installation to avoid punctures or tears. Maintenance is minimal, as once installed, the film can remain in place throughout the season. In terms of aesthetics, the crystal clear appearance is a plus, but some users might find the plastic film less appealing compared to more permanent insulation solutions. Sound insulation capabilities are not specifically highlighted, so it may offer limited noise reduction.
