Bronze AT 20 Ex - bronze mirror reflective film
Bronze AT 20 Ex is a bronze mirror film for external application. It is made by sputtering (metal deposition), which gives glass an elegant bronze lustre - a softer, more natural look than classic silver mirror films - while providing strong protection from intense sun. You will find it in our reflective window film and mirror window film sections. On window-film-solaris.co.uk you can order it cut to size for your exact measurements.

Elegant bronze finish
The chic bronze tint transforms glass surfaces and integrates style with sun shielding. The shade adapts to lighting conditions through the day, and sunlight passing through the glass takes on a warm tone. The film suits flat panes of any window size.
One-way privacy during the day
Bronze AT 20 Ex offers one-way visibility: you view the outside while indoor activities stay confidential behind the reflective surface. The effect works towards the brighter side, so it protects your privacy in daylight hours; at night, with the lights on inside, the effect reverses - use curtains or blinds after dark. Visit our section on one-way window films for further information.
Sun and heat control: stopped before the glass
As an exterior film, Bronze AT 20 Ex rejects 83% of total solar energy before it reaches the glass, so the pane itself does not heat up - a safe choice for double glazing. It reflects 46% of visible light, letting 19% of daylight through, which means cooler interiors, less glare and reduced reliance on air conditioning. It also blocks 99% of UV radiation, protecting you and your furnishings from fading. For more outdoor models see our external window films section.

Alternative options
- Bronze AT 35 Ex - the lighter bronze model, when keeping more daylight matters.
- Omg 30 Ex - a light silver exterior mirror film.

Bronze AT 20 Ex is self-adhesive, with the adhesive layer under a clear liner. Use a mounting solution for a swift, bubble-free installation - our online guide for self-adhesive glass films provides full instructions, and the tool kit included with every order makes the job faster and cleaner.
