Fiberglass Reinforced Plastic (FRP) duct products from Perry Fiberglass serve a wide array of applications including Aquatic, Underground and Industrial & Commercial. Our Class 1 rated ductwork, Perry 20S Low Smoke™, and its double-wall counterpart, Perry 20S-IR7, are unique in the industry and have found widespread acceptance.

Perry Fiberglass FRP duct products offer numerous advantages over traditional ducting materials such as galvanized, stainless steel and PVC coated metals. Below you'll find some of the many reasons we feel Perry Fiberglass FRP duct represents the best the industry has to offer:

Material Integrity
Perry Fiberglass FRP duct is filament wound with glass and resins formulated for your specific application. The duct is manufactured to comply with recognized industry standards and can be customized to your exact specifications.

Filament winding provides greater hoop strength, resulting in a much stronger duct than other methods of construction such as hand lay-up, and is far superior to metal products in many environments. Perry Fiberglass FRP duct is lighter than steel while offering superior corrosion qualities and equal air flow performance.

Superior resistance to corrosion and leakage are hallmarks of Perry Fiberglass FRP duct. The same corrosion resistant qualities can be maintained on both the inside diameter (ID) and outside diameter (OD) allowing for a wide range of applications.

Perry Fiberglass FRP duct products meet the Flame and Smoke requirements of a Class 1 Flame and Smoke (25/50 respectively) duct per Underwriter's Laboratories (UL) 181 and Uniform Mechanical Code (UMC) 10-1 and are verified by an ASTM E-84 testing laboratory recognized by the following building code organizations under the Council of American Building Officials: ICBO; BOCA; SBCCI.

Perry Fiberglass FRP duct is available in long lengths -- up to 50 feet. A complete complement of standard FRP fittings and special shapes are manufactured. The light weight duct is exceptionally strong, making it easy for workers to handle on the job site. Factory manifolding, color options and custom wall thickness are all available to meet your unique job requirements.

A ductwork system from Perry Fiberglass can be sealed to achieve a liquid-tight system. This assures efficient movement of the exhaust air while removing any risk of contamination.

Ease of Use
Perry Fiberglass FRP duct can be field installed using simple tools. The joining material is the same glass and resin combination as the FRP ductwork. Perry Fiberglass can provide field training for the installing personnel. Optional flanged or bell and spigot joints can be provided upon request.

Superiority of Pre-Insulated Duct
Perry 20S-IR7 pre-insulated double wall FRP duct offers superior performance over field-applied insulation. Advantages include: assured uniformity of insulation; permanent protection of insulation by encasement on both ID and OD by a FRP shell; permanent vapor barrier to prevent moisture from condensing within the insulation; and superior thermal conductivity.
