The “Wind Handler Insulated TU Large Diameter” flexible duct is a two single-ply neoprene coated yellow polyester fabric plies protecting an insulation barrier with a black external wearstrip reinforced with a spring steel wire helix. This is the ultimate insulated air ventilation duct. The two single plies of neoprene coated fabric offer excellent weathering and ozone characteristics. Weather resistance is the ability of a material to prevent deterioration, damage to material or any sort of deterioration due to prolonged exposure to harsh environmental and weather conditions. In conjunction with the polyester fabric which adds mechanical stability and reduces the chance of ripping and tearing, the duct walls of this hose display excellent weather (i.e., outdoor) and moisture resistance. Since this flexible duct’s wall is made from a rubber coated polyester, it has excellent tensile strength. The tensile strength of a material is the maximum stress that can be applied to it before it breaks. The high tensile that this hose displays makes for a hose that will resist ripped when flexed constantly over time. This large diameter insulated flexible duct is designed to withstand exposure to the elements — sun, rain, and wind. If a product resists the penetration of water.

The “Wind Handler Insulated TU Large Diameter” Duct is made to order and is available in diameter sizes of 20-, 22-, 24-, 30-, 36-, and 40-Inch I.D. Custom I.D .sizes up to 48 Inch and all sizes and in maximum lengths of 50 continuous feet (contingent on the diameter size). This duct is produced with sewn cuffed ends, however custom cuffs (e.g., enlarged, funnel, reduced, belted, etc.) can be added based on request. This insulated ductwork has an R-Value of 4. This thickness of the fiberglass insulation wrap is ideal for a transportable hose that needs to be flexible and compressible. R-Value measures how well insulation can resist heat flow. R-Value of ductwork refers to the insulation around a duct and how well it prevents heat from entering or escaping ducts. Higher R-value insulation is thicker and reduces the flexibility of a duct. The “Wind Handler Insulated TU Large Diameter” has a compression ratio of 5 to 1 and weighs about 2 lbs per foot in a 20” diameter size. Therefore, a 25 foot length of this flexible duct would compress down to a five foot coil and would only weigh about 50 lbs. This makes for a hose that is easy to manage if it requires to be moved.
