    In 2015, the International Energy Conservation Code (IECC) made a new change regarding the thermal resistance requirements for duct insulations in unconditioned spaces. Specifically, the code called for ducts in unconditioned spaces in climate zones 5-8 to be insulated with R-12 insulation.1 (Please see the complete code for all details and any exceptions.) In terms of insulation, designers can expect that the higher the R-value, the greater the insulating power of the insulation.

    In most applications, the primary feature of a thermal insulation material is its ability to reduce heat exchange between a surface and the environment, or between one surface and another surface. This is known as having a low value for thermal conductivity. Generally, the lower a material’s thermal conductivity, the greater its ability to insulate for a given material thickness and set of conditions.

    If it is really that simple, then why are there so many different terms, such as K-value, U-value, R-value, and C-value? Here is an overview with relatively simple definitions.

    While both residential and commercial HVAC systems serve the same purpose of heating, ventilating and cooling, they vary drastically in terms of mechanism and parts. This is because addressing the need for comfort in a home varies drastically when compared to a work space. Following are 7 major differences between residential and commercial HVAC units…

    The average commercial building attributes 40% of its energy costs to heating, cooling, and ventilation, according to estimates from the US Department of Energy. For the typical office building, that equates to 7.5% of its annual operating expenses, on average.

    Finding efficiencies in your facility’s HVAC system can result in significant savings on operating costs. But it can also yield even bigger returns in non-energy benefits. Improvements in comfort, indoor air quality, and equipment reliability can all be achieved with HVAC maintenance and upgrades.

    We recently took some time with John Newland, President of SPIDA (the Spiral Duct Manufacturers Assocation), to learn more about the association and the benefits it offers to contractors, engineers, and manufacturers alike. Read more about what John had to say about the state of the industry, trends he sees coming our way, and the benefits of SPIDA. 

    Can you give us a brief introduction to who you are and your experience in the industry?

    When Giffin Sheet Metals Ltd. needed a large quantity of aluminized steel for an automotive project in Alliston, Ontario, the Toronto contractor reached out to a U.S. supplier in southeastern Michigan.

    Aluminized steel is harder to come by in Canada and the company required several hundred thousand pounds. It was a transaction the 70-year-old company had done many times before, and with the 24-year-old North American Free Trade Agreement, such cross-border purchases were virtually hassle-free.

    With the recent political whirlwind that has permeated the HVAC industry, many suppliers, manufacturers and contractors are in a state of flux. We are all waiting to see how things play out in the metals market after Trump administration’s March 8 announcement of new import tariffs on steel and aluminum.

    As the insulation industry strives to help equip new talent with the skills and tools necessary to fabricate and install well-detailed, effective insulation systems, many programs are being developed by major players in the insulation industry to meet the growing need for education. For example, NAIMA (the North American Insulation Manufacturers Association) developed the Duct Instruct Program – a train-the-trainer program designed to help ensure that vocational schools are equipped to properly train their students on duct board fabrication.

    “Forward-thinking contractors keep duct insulation in the forefront as they understand the impact it has on temperature loss through the duct system,” said David Richardson, curriculum developer and trainer, National Comfort Institute (NCI). “It’s almost always a focal point of any duct renovation or upgrade they perform.”
