Why Monoxivent UnderDuct fiberglass HVAC ductwork is superior

• DURABILITY:
• provides excellent resistance to corrosion and leakage.
• corrosion resistance qualities maintained throughout inside diameter(ID) and outside diameter (OD) allowing for a wide range of applications.
• EASE OF USE:
• 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
• duct is impervious to minerals or salts present in soil.
• EFFICIENCY:
• 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.
• MATERIAL INTEGRITY:
• filament wound with two chemically inert materials – glass and resin.
• finished product provides longer underground service life than galvanized sheet metal, stainless steel, or PVC coated sheet metal.
• filament winding provides greater hoop strength resulting in a stronger duct than other methods of construction such as hand lay-up.
• finished product is lighter than steel while offering superior acoustical qualities and corrosion resistance.
• TESTING:
• products meet the Flame and Smoke requirements of a Class 1 duct per Underwriters Laboratories (UL) 181 and Uniform Mechanical Code (UMC) 10-1.
• verified by an ASTM E-84 testing laboratory
• recognized by the building code organizations under the Council of American Building Officials: ICBO; BOCA; SBCCI.
• VERSATILITY:
• 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.

AK Duct is classified as High Density Polyethylene (HDPE), which is a closed cell plastic material with an additional high thermal property. It is unique to other materials because it is manufactured with food grade plastic that is safe for humans and the environment. The preformed ductwork has the characteristic of a smooth low friction surface that is resistant to mildew, mold, and Radon. Under pressure it will not crack, is non-toxic and it is recyclable. In addition, the ductwork is self-insulating, adjustable and easy to install. A thermal efficiency performance that has test proven equivalency to deliver effectiveness comparable to underground PVC coated spiral and PVC ductwork wrapped in R10.
