Special-Lite Fiberglass Reinforced Polyester (FRP) Doors are exterior doors designed with the heavy-duty rigors of high-traffic school entrances and exits in mind. Additionally, Special-Lite FRP Doors are light-weight (yet durable) and energy-efficient. Each door has a proprietary urethane core injected, comes GreenGuard certified, and exceeds ASHRAE Energy Standards.

Furthermore, Special-Lite offers a 10-year, 100% parts and labor warranty on its products (certain product exclusions apply*).

*The BasiX™ Door and Interior Architectural Products each carry a separate warranty. Contact Special-Lite, Inc. for details.

Optional protections include:

  • Blast Doors
  • Ballistic Doors
  • Florida Building Code (FBC) approved High-Velocity Hurricane Zone (HVHZ)

Typical applications for the Special-Lite Fiberglass Reinforced Polyester Doors (SL-17 / SL-20) include K-12 schools, public buildings, sports complexes, water, and wastewater treatment facilities, and in Schools, Property Management and Hospital scenarios where doors are put through an excessive amount of use and punishment.
