Can You Use Window Tint On Double Pane Windows?

Yes, you can use window tint on double-pane windows, but it’s vital to proceed with caution and be well-informed about the type of tint you’re applying. Double-pane windows, also known as insulated glass units (IGUs), consist of two glass panes separated by a space filled with air or an inert gas, like argon, to improve thermal efficiency.

When applying window tint to double-pane windows, consider the following to avoid potential issues…

1. Thermal Stress

  • Risk – Certain types of window tints can increase thermal stress on double-pane windows. Dark or highly reflective tints can absorb a significant amount of solar energy, which may lead to an uneven temperature distribution across the glass. This can cause the glass to expand differently in various areas, potentially leading to cracks or breaks.
  • Solution – Opt for tints specifically designed for use on double-pane windows. These tints are engineered to minimize thermal absorption, reducing the risk of thermal stress.

2. Manufacturer’s Warranty

  • Consideration – Applying window tint to double-pane windows may void the manufacturer’s warranty. It’s necessary to check the warranty terms before proceeding with tinting.
  • Advice – Some window manufacturers offer their solutions or approve certain types of window films, so consulting with them before making a decision is wise.

3. Professional Installation

  • Recommendation – Given the potential complexities and risks associated with tinting double-pane windows, professional installation is highly recommended. Professionals can assess the specific needs of your windows, recommend suitable films, and ensure the tint is applied correctly to avoid damage.

4. Selecting the Right Film

  • Solar Control Films – These films can help reduce heat gain and glare while minimizing the risk of thermal stress. They’re available in various shades and reflectivity levels to suit different needs.
  • Low-E Films – Low-emissivity (Low-E) films not only reduce heat gain in the summer but also help retain heat in the winter, further enhancing the energy efficiency of double-pane windows without significantly increasing thermal stress.

5. Awareness of Local Climate

  • Climate Consideration – The effectiveness and suitability of window tint can also depend on your local climate. In areas with high sun exposure, solar control films can offer significant benefits. In cooler climates, Low-E films might be more appropriate to maximize energy savings year-round.

In summary, while window tint can be applied to double-pane windows to improve energy efficiency, reduce glare, and protect against UV rays, it’s crucial to choose the right type of film and consider professional installation. This approach ensures you enhance the functionality and longevity of your double-pane windows without risking damage.
