Acrylic - Type of material used to form faces.

Adhesion - The force that holds the surface of one material to another. The strength of adhesion is affected by the type and condition of the surfaces in question and the adhesive used. Generally, the surfaces need to be clean and porous enough to allow for a certain amount of penetration by the adhesive.

Adhesive - A material or substance able to bind and hold two surfaces together. Examples include glue, epoxy, and tape.

Aluminum - A lightweight metal material used in sign panels, poles, and frames. It is strong and durable in relation to its weight, and resistant to rust and corrosion.

Amortization - In accounting, this term means the time in which an asset has been depreciated. As it relates specifically to signage, this term also applies to the “grace” period in which a sign must be replaced or removed. In this instance, a sign followed zoning laws or codes that were then changed; the no-longer compliant sign must be replaced after the amortization period ends.

Animated Sign - A sign that uses the sequential switching on and off of graphically arranged fluorescent lamps, cathode tubes, LEDs or incandescent so as to provide the illusion of movement.

Cabinet Sign - A sign structure consisting of the frame and face(s), not including the internal components, embellishments of support structure.

CAD - Computer aided design software.

Canopy - A permanent fixture, often made of metal or glass, that is attached to a structure. It differs from an awning in that its aim is not to provide shelter.

LED - Light Emitting Diode.

Letter Spacing - A typographic term for the space between letters and words.

Lifetime - A measure of how long the light source lasts. Here there are a few things to consider. First, LEDs do not burn out, but typically will degrade over a period.
