Overview Sign foam (also known as high density urethane or HDU board)
is a great alternative to wood for interior and exterior signage. In fact, many signs that appear to be carved from wood are actually carved out of sign foam.

Sign foam is:

  • Light weight
  • Easy to fabricate
  • Easy to paint
  • Easy to glue

In addition, sign foam is rot, moisture, and insect resistant.

Whether you are building an interior or exterior sign, sign foam board provides the sign designer and manufacturer much flexibility and durability.
