  • The company’s services, primarily as specialty glass fabricators and distributors
  • Hollander’s historic line of restoration window glass, including glass appropriate to periods over the last 300 years
  • Notable projects using Hollander’s historic line, including skylights at the Lincoln Memorial in Washington, D.C. 
  • Challenges for window restoration projects, including more stringent energy codes
