FRP Ductwork

Fiberglass reinforced plastic (FRP) duct products from Perry Fiberglass serve a wide array of applications including municipal, industrial and underground.

Why Choose Perry Fiberglass For Your Duct Needs
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.

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 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.

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 joints can be provided upon request.

Superiority of Pre-Insulated Duct
All of our ductwork is available in both single-wall and double-wall (factory insulated). Perry Fiberglass 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.

Configuration Options
Below are the basic configurations of our products.
  • Shape
    Typical shapes for filament wound construction are round and
    rectangular. Engineering assistance is available for designing projects requiring non-standard construction.
  • Diameter
    Duct diameters are available from 2" - 168". Rectangular sizes are available as required for your projects. The same range of sizes are available in our double wall duct (insulated).
  • Lengths
    Lengths up to 40' are available.
  • Factory Manifolding
    All of our FRP ductwork can be factory manifolded to save the installing contractor time and money.
