An Experienced Team You Can Count On!

Monoxivent’s design team includes engineering, layout and custom solutions.  This, coupled with a manufacturing source with over 40 years of experience, a 90,000-sq. foot facility and state-of-the-art equipment makes Corrosion Composites an excellent source for FRP products.
Furthermore, all of Corrosion Composites‘ duct fabricators have at least five years experience in fabricating corrosion resistant duct for wastewater applications. A reference list of completed waste water projects will be provided with every quote.

Why our fiberglass reinforced plastic UnderDuct is superior

Monoxivent’s UnderDuct fiberglass HVAC ductwork provides excellent resistance to corrosion and leakage. The corrosion resistance qualities are maintained throughout both the inside diameter (ID) and outside diameter (OD) allowing for a wide range of applications.
Monoxivent’s UnderDuct fiberglass duct can be directly placed onto a pea gravel bed in a graded trench, then backfilled with pea gravel eliminating concrete encasement. Simple joining methods provide for easy and quick installation, and the FRP duct is impervious to minerals or salts present in soil.
Monoxivent’s UnderDuct systems can be sealed to achieve a water and air tight system. A leak-free system and smooth interior surface will ensure the air reaches its destination efficiently and without contamination.
Monoxivent’s UnderDuct FRP fiberglass duct is filament wound with two chemically inert materials – glass and resin.  The finished product provides longer underground service life than galvanized sheet metal, stainless steel, or PVC coated sheet metal.  The filament winding provides greater hoop strength resulting in a stronger duct than other methods of construction such as hand lay-up.  The finished product is lighter than steel while offering superior acoustical qualities and corrosion resistance.
Monoxivent’s UnderDuct has been tested by ICC-ES and listed (PMG-1171) and shown to be compliant with the following building codes: IMC, IRC, UMC, and CMC.
Corrosion Composites adhere to ASTM, SMACNA, AWWA, and other industry standards.
Monoxivent’s UnderDuct FRP products are available in straight lengths, standard and custom fittings, or in shop fabricated sections. Single wall duct can be shipped in prefabricated assemblies. Pre-insulated double wall duct has many advantages, including assured uniformity of insulation, permanent protection of insulation, and all-in-one installation.
