When tinting double-pane windows, it’s generally better to apply the tint film to the inside surface of the glass rather than the outside.
Here’s why…
- Protection from Wear and Tear – Tinting the inside surface of double-pane windows provides protection for the tint film from external elements such as weather, debris, and UV radiation. Placing the film on the outside exposes it to these elements, increasing the risk of damage and reducing its lifespan.
- Ease of Installation – Installing window tint film on the inside surface of double-pane windows is typically easier and more straightforward than applying it to the outside. Access to the interior surface is easier, and there is less risk of damage during installation compared to applying the film on the outside.
- Aesthetic Considerations – Placing the tint film on the inside surface of double-pane windows maintains a smooth, uninterrupted appearance from the exterior, which can be more visually appealing than having the film applied to the outside. This is particularly important for maintaining curb appeal in residential or commercial settings.
- Preservation of Sealant and Insulating Gas – Tinting the inside surface of double-pane windows helps preserve the integrity of the window seals and insulating gas (if present) between the panes. Applying tint film to the outside may interfere with the seals and expose the film to external elements, compromising its effectiveness and potentially affecting the insulating properties of the window.
- Regulatory Compliance – Some jurisdictions have regulations or restrictions regarding the use of window tint film, particularly for residential or commercial buildings. Installing the film on the inside surface of double-pane windows helps ensure compliance with these regulations and avoids potential legal issues.
Tinting the inside surface of double-pane windows is generally the preferred method due to its advantages in terms of protection, ease of installation, aesthetics, and preservation of window integrity. However, it’s essential to choose high-quality tint film and have it installed professionally to ensure optimal performance and longevity.
