It starts with the building envelope. As a passive measure with no associated on-going operational costs, choosing the right building materials can play a critical role when it comes to driving down energy costs and improving building performance. There are various forms of insulation placed in walls i.e. rigid board, mineral wool, fiberglass, spray foam, pre-insulated metal panels.
What about the insulation used in ductwork? It is important for the air traveling within the ductwork to remain at the temperature it is supposed to for delivery throughout the building. Insulation can be used as a liner inside the duct, or wrapped around the outside of the duct. Properly installed duct insulation can help prevent condensation as well as air leakage.
Duct leakage can contribute significantly to energy loss in buildings. The U.S. Department of Energy had estimated duct leakage to be the cause of almost $25 billion in energy losses.
The Kingspan KoolDuct System is an advanced and innovative phenolic duct system that comprises premium-performance panels, fabrication methods, coupling systems and a complete line of accessories. Ductwork using Kingspan KoolDuct panels can be fabricated to pre-insulated rectangular ductwork in sections up to 13 feet (3.93 meters) long for faster installation. KoolDuct weighs up to 72% less than ductwork constructed from galvanized sheet metal insulated with mineral fiber insulation. The fiber-free, rigid phenolic insulation core minimizes the risk of loose fibers entering the airstream through the ductwork, since distributed air does not come into contact with insulation material that produces loose fibers.
KoolDuct is the first phenolic pre-insulated ductwork in the world to be UL 181 Listed as a Class 1 Air Duct and can easily attain a SMACNA Class 3 air leakage rating. It reduces energy usage and running costs, and can help cut operational CO2 emissions.
The Kingspan KoolDuct system is designed for use in both new build and retrofit projects in residential and commercial applications. The ductwork can be installed indoors, outdoors, concealed above false ceilings and below raised floors. It is especially suitable for specification projects where non-fibrous insulation may be preferred such as pharmaceutical industries, clean air and hygiene controlled environments, schools, and hospitals.
