Duct Sheet Metal Thermal Conductivity

Architects designers and mechanical engineers who specify hvac systems want to optimize thermal efficiency while dampening unwanted noise to make structures as comfortable as possible for their occupants.

Duct sheet metal thermal conductivity.

We offer a range of fiberglass duct wrap solutions that provide traditional sheet metal ducts with improved thermal insulation. Thermal conductivity k is used in the fourier s equation. Installed cost savings lightweight duct reduces installation labor costs. Calculate overall heat transfer coefficient.

Our duct wrap is available in a variety of densities thicknesses and with or without facings. Fabricated into the duct itself duct board offers both sound and thermal control. It can be installed with sheet metal screws. 2 rigid boards supplied in sheet form.

Royal metal products 8 x 4 x 4 in. High r values with thin insulation low thermal conductivity with thicknesses of 7 8 and 1 3 16. Round metal duct pipe. Flange insert box with gasket.

Sheet metal duct lined with fibrous glass insulation duct liner secured to sheet metal with adhesives plus metal fasteners available in thicknesses from 1 2 to 2 in. Round metal duct pipe. A low thermal conductivity allows thinner insulation to achieve the required thermal performance. Thermal conductivity k is the quantity of heat transmitted due to an unit temperature gradient in unit time under steady conditions in a direction normal to a surface of the unit area.

The thermal conductivity k value of kingspan koolduct panels is 0 146 btu in hr ft 2 f at 50 f astm c 518 the lowest of any commonly used insulation material. It provides acoustical and thermal performance for lined metal ducts. Fiberglass duct liner insulation helps manage heat transfer and unwanted sound.
