They are thin, transparent sheets made of polyester or other materials that are applied to the surface of windows or glass surfaces to provide protection from impacts, UV rays, and heat.
The purpose of these films is to protect glass from breakage, reduce fading of interior furnishings, and increase energy efficiency by reducing heat transfer.
There are many companies around the world manufacturing these films, including 3M, Madico, and Llumar, to name a few.
When choosing the right window or glass protection film, there are a few guidelines to follow:
- Determine the specific purpose of the film (impact protection, UV protection, energy efficiency, etc.)
- Consider the location and type of glass (e.g., tempered glass, insulated glass, etc.)
- Consider the type of adhesive used to apply the film
- Check the warranty offered by the manufacturer
- Evaluate the cost and choose a product that fits your budget.
It’s important to note that not all window protection films are created equal, so it’s crucial to do your research and choose a high-quality product from a reputable manufacturer.
A good window safety and security film should have the following characteristics:
- Thickness: A thickness of at least 7 mil (0.007 inch) is recommended for basic protection. Thicker films provide better protection against impacts, but they can also be more difficult to install.
- UV protection: A good window film should provide a high level of ultraviolet (UV) protection to prevent fading of interior furnishings and protect occupants from harmful UV rays.
- Adhesion: The film should be easy to apply and should have a strong bond to the glass surface.
- Impact resistance: A good window film should be able to resist impacts from objects such as hail, debris, and other flying objects.
- Shatter resistance: The film should be able to hold the glass in place if it shatters, preventing glass fragments from spreading and causing harm.
- Energy efficiency: The film should help reduce heat transfer, which can improve energy efficiency and reduce cooling costs.
- Visible light transmission: The film should not significantly reduce the amount of visible light that enters the building, which can impact the appearance and brightness of the interior.
- Warranty: A good window film should come with a warranty that covers any defects or issues with the product.
- Manufacturer reputation: Choose a window film from a reputable manufacturer with a track record of producing high-quality products.
- Price: A good window film should offer a balance between quality and cost, providing adequate protection at a reasonable price.
