Unico Aluminum Supply Air Tubing R8 Insulation - 25ft (4pcs) UPC-25-R8-4

General

The Unico System Unico aluminum supply tubing is a 2-inch Unico Flexible Air Duct. It provides an insulated vapor barrier to prevent condensation from forming on the outside of the duct. However, the aluminum supply tubing is not designed to reduce the high velocity air noise. Therefore, it is essential to use the UPC-26sound attenuator at the end of every branch duct to prevent unwanted noise. The supply tubing is offered with several different choices of insulation thickness. In most cases, the standard supply tubing should be used. However, for extremely cold or humid environments or where the local building code requires a specific R-factor and the duct is installed in an unconditioned space, use the R4, R6, or R8 products. The R4, R6, and R8 ducts have thicker and heavier insulation than the standard sound attenuator to reduce thermal losses.

Application

The UPC-26 sound attenuator significantly reduces sound from the outlets. Therefore, for proper noise control, it is recommended to use at least 3 feet of the UPC-26 sound attenuator at the end of every two-inch branch run. An entire branch duct can be made of one or more lengths of the UPC-26 sound attenuator. However, because the aluminum core tubing is stronger than the sound core, for lengths greater than 12-feet it is best to use almost all UPC-25 aluminum supply tubing with a 3-foot length of sound attenuator at the end.

Where runs are required to be installed in unconditioned spaces every attempt should be made to limit the length of the duct run to 12-feet or less using the proper R-factor for the application. However, as an air duct, there is no limit to the length used other than its ability to deliver the air.

Construction

The aluminum supply tubing has a 2-inch inside diameter supplied in 25-foot lengths and can be cut as needed. The standard supply tubing (UPC-25) is made of three layers. These layers combined have an R factor of 3.2 °F-hr-ft2/Btu.


The inner layer/core is made of two-ply corrugated aluminum. The outer jacket is made of two-ply reinforced reflective mylar; providing a vapor seal to prevent leakage and moisture migration, and increases the insulation factor by reducing the radiant heat transfer. Fiberglass blanket insulation fills the void between the jacket and the nylon core.

The standard duct has one insulation layer 0.75 inch thick; the R4 duct insulation layer is 1.0 inch. The R6 and R8 duct both have two layers of insulation and a double vapor seal; The R6 total insulation thickness is 1.5 inches and R8 total insulation thickness is 2.0 inches.
