Beautiful Signs for a Better Planet


Exterior ADA signs are often overlooked aspect of sign system design.  It is not unusual for designers to specify the same design and materials for interior and exterior applications with disastrous results.  Typical ADA signs fail when exposed to exterior conditions.

Failures usually fall into all or one these four categories:

  1. Adhesive holding layers of plastic together delaminates
  2. Plastic integrity fails due to temperature swing and UV exposure
  3. Braille balls fall off due to temperature swings; many braille balls are held in pace through tension alone. Since plastic expands and contracts with temperature swings braille are often either squeezed out in the cold or drop out in the heat
  4. UV exposure causes colors to fade and not meet contrast requirements of the American with Disabilities Act

The Exterior ADA Sign Solution

Green Dot Sign® is committed first and foremost to sustainable signage solutions.  Rather then fossil fuel based plastics we use infinitely recyclable metals as the base for our exterior ADA signage.  Each sign is 100% recyclable at end of life and during manufacture we capture and recycle all waste.

What are Green Dot Sign® Exterior ADA Signs Made From?

Instead of plastic, we machine solid aluminum or bronze plate.  Each sign is then painted, letters and pictograms are sanded to expose the natural metal, then a top coat is applied.  All paints are automotive grade, two part catalyzed paints with the longest possible exterior life.  Fading will occur around 10 years, but usable life is much longer.

Where are Exterior ADA Signs Required?

If your facility has specific rooms accessed through exterior doorways ADA compliant signage is required.  Common examples include restrooms, mechanical rooms and similar permanent rooms and spaces.

For questions about whether or not a sign is required please visit our ADA sign requirements page.
