The heating, ventilation and air–conditioning (HVAC) industry is in the midst of a dynamic era, however air–distribution ductwork remains virtually unchanged since the early 1900s.
Several factors have introduced the need to revolutionize HVAC ductwork. Energy use has continued to escalate, and thus the demand for energy reducing solutions has intensified. Requirements for clean air are becoming increasingly prevalent. Speed of construction has become a valuable asset. Floor space and headroom are under constant pressure.
Traditionally, HVAC ductwork is constructed from galvanized sheet steel, which is installed first and then insulated separately as a second operation. The Kingspan KoolDuct® System however, is an advanced and innovative pre–insulated rectangular HVAC ductwork system, which is installed in a single–fix.
The Kingspan KoolDuct® System eliminates virtually all of the problems associated with galvanized sheet steel, fiber glass duct board and pre–insulated rigid polyiso (PIR) ductwork systems whilst, at the same time, offering additional advantages to the specifying engineer, the architect, the M&E contractor, the fabricator, the facilities manager, the property developer and the building owner.
Ductwork fabricated from The Kingspan KoolDuct® System can reduce air–leakage rates to a fraction of those typical of rectangular sheet metal ductwork. This cutting edge System thus offers the triple benefits of cutting energy use, cutting operational carbon dioxide (CO2) emissions and cutting costs.
As a result, The Kingspan KoolDuct® System should be considered the ductwork system of choice, where low embodied environmental and low operational environmental impacts are key requirements.
The Kingspan KoolDuct® System comprises premium performance Kingspan KoolDuct® panels, fabrication methods, coupling systems and a complete line of accessories to produce pre–insulated rectangular ductwork in sections up to 13 ft / 3.93 m long.
Kingspan KoolDuct® panels are available in the following standard thicknesses and corresponding installed R–values:
7/8” = R–6.0 ft²·hr·°F/Btu /22 mm = R–1.047 m²·K/W; and
1 3/16” = R–8.1 ft²·hr·°F/Btu /30 mm = R–1.428 m²·K/W.
This allows ductwork to be fabricated with different wall thicknesses to suit different performance specifications. Kingspan KoolDuct® panels comprise a fiber-free rigid thermoset phenolic insulation core faced with branded silver aluminum foil on one side and plain silver aluminum foil on the other.
In addition, there are several coupling systems available to suit different installation and project specification requirements. They include the 4–bolt, aluminum grip and Tiger Clip systems.
The design of ductwork, including fittings, fabricated from The Kingspan KoolDuct® System follows the same calculation principles and duct sizing methods as are used for ductwork constructed from galvanized sheet steel.
Kingspan Insulation offers a complete product line, providing all materials, tools and accessories
necessary for the effective fabrication of ductwork from The Kingspan KoolDuct® System.
