The heat and glare problem Exterior Silver 20 2mil answers
Madico Exterior Silver 20 2mil is for glass that lets in more sun, heat or glare than the room can use. Interior film can be a poor match for laminated or triple-pane glass, which is why some windows cannot take it. Those windows still collect full sun and glare all day.
How Exterior Silver 20 2mil cuts heat and glare
RS 20 E rejects 81% of total solar energy and 95% of infrared, passes 18% of visible light and cuts glare by 80%, with a solar heat gain coefficient of 0.19 on single-pane clear glass. Madico adds that the film provides shatter resistance and can help hold glass together if a window breaks.
Where Exterior Silver 20 2mil fits best
NorthGuard suggests Madico Exterior Silver 20 2mil for jobs like these.
- Laminated or triple-pane glass, where Madico's own guidance points to an exterior film.
- Large storefront or curtain-wall areas in strong sun, where 65% of visible light reflected outward suits the building.
- Rooms that want daytime privacy, with only 18% of visible light coming through.
- Buildings where Madico's note about holding interior heat in during winter is a bonus.
What Exterior Silver 20 2mil will not do
Madico Exterior Silver 20 2mil has limits that NorthGuard states before any quote.
- The film goes on the outside, so install depends on safe access to each window's exterior and on the weather.
- The finish is a strong, uniform mirror from outside, and rooms behind it get dimmer.
- Madico publishes no strength numbers for this film, so treat it as a solar film with a secondary glass-holding benefit.

Exterior Silver 20 2mil questions and answers
NorthGuard answers these questions about Madico Exterior Silver 20 2mil with Madico's published data.
Why is Exterior Silver 20 applied to the outside of the glass?
Madico positions RS 20 E PS SR for jobs where an interior install is not possible or is too risky, such as laminated or triple-pane glass. Putting the film on the outer face avoids that problem. The glass still gets the same reflective silver finish.
How much heat does Exterior Silver 20 reject?
Exterior Silver 20 rejects 81% of total solar energy and 95% of infrared on single-pane clear glass. Its solar heat gain coefficient is 0.19 and its shading coefficient is 0.22. Madico calls these typical values, not a specification for every window.
How reflective is Exterior Silver 20?
Exterior Silver 20 reflects 65% of visible light from the outside and 60% from the inside, while passing 18%. That gives the building a sleek, uniform silver face by day. Glare drops by 80%.
Does Exterior Silver 20 help if the window breaks?
Madico says the film can help hold glass together if a window breaks, and its guide lists shatter resistance. Madico publishes no tensile or break strength figures for this film. Treat it as a solar film first, not a dedicated safety film.
