Traditionally dominated by metal, design engineers and manufacturers are increasingly converting to thermoset composites or Fiber Reinforced Polymers (FRP) for their molded materials needs in the HVAC industry.  Largely, the increase in demand for FRP in the HVAC industry has been a result of two factors: the rising cost of metals and increased product performance requirements.

While the product needs are diverse in the HVAC industry many choose FRP products over aluminum, stainless steel, light gauge steel, and coated metal for applications where high strength-to-weight ratio, acoustical qualities, air flow performance, smoke resistance, heat resistance, and corrosion resistance are important.

FRP has the ability to withstand stringent environments; exposure to heat, corrosives, and condensation while maintaining strength. FRP have superior sound dampening properties because of their rigidity. Conversely traditional sheet metal assemblies often create unwanted ambient noises, such as creaking.


We have unmatched design intelligence that can provide product development and support.  At Beetle Composites we can create new products as well as assist you with incremental improvements.  We offer great products that will perform well in a wide variety of HVAC applications ranging from industrial ventilation and corrosive environments to underground and exhaust ductwork systems.

  • Full Vacuum and Pressure Services
  • Filament wound or Contact Molded
  • Full range of fittings, connections and joints
  • Custom Formulations (i.e. corrosion and abrasion resistance)
  • Round, Elliptical, and Rectangular Duct Options
  • Single-Source Design Build Capabilities


Regardless of whether you are working on industrial construction, commercial construction, underground, or aquatic environments, composites are the most cost-effective materials choice, with the longest life cycles when compared to conventional materials of equal sizes.  For example, with respect to duct and pipe, it is well known that Fiber Reinforced Polymers (FRP) have a proven longer underground service life than galvanized sheet metal, stainless steel, or PVC coated sheet metal.


Worldwide use of FRP products in the HVAC industry include, but are not limited to: ductwork, airways, air conditioning housing, heat exchange housing, cooling coil drip pans, ventilation, exhaust, condensing unit components, and blowers.


  • Noise Reduction- sound dampening qualities to reduce ambient noise
  • Part Consolidation
  • Structural Integrity Under Elevated Temperatures
  • Custom Shapes and Wall Thicknesses
  • Optimal Air Flow Performance
  • Custom Formulations- smoke, heat, and corrosion resistance
  • Long life cycles

FRP is a cost-effective material choice that is ideal for many HVAC applications.  Whether it’s new construction, incremental improvement, or a retrofit for structural upgrade, the light weight of fiberglass contributes to overall savings, starting with lower transportation costs. With our FRP products there is less need for heavy lifting equipment and installation is faster which results in less distress and disruption to the community.


FRP has great structural properties such as dimensional stability and good rigidity.  The rigidity and self-supporting nature of fiberglass means there is less dead weight and less structural material is required.  This factor is important regardless of your industry because it contributes to the elimination of unnecessary resource consumption and bringing down costs.

FRP is often chosen over other materials in the HVAC industry for having a life cycle that exceeds other products by remaining resistant to rust, mold, mildew, and corrosion. By increasing the useful lifespan compared to other products such as aluminum or coated metal, fiberglass’s durability reduces the need for replacement, repair or repainting.


We have experience that runs deep.  We’ve been around for over 50 years and in that time we’ve demonstrated our commitment to engineering superior composite products for a wide range of uses, including many in the HVAC industry.  Whatever your need, our streamlined in-house design and manufacturing capabilities will enhance your product.
