Guide to Insulation Specifications

Keeping insulation specifications up-to-date is a constant battle for mechanical engineers and manufacturers of the following factors: Changes to industry standards (i.e. ASTM) Changes with insulation manufacturers (mergers & acquisitions) Energy standard/code updates (i.e. ASHRAE, IECC®) Manufacturer product line additions & deletions Numerous other factors Mechanical insulation specifications for building mechanical and process systems, such…

Self Seal Pipe Insulation

The U.S. Energy Information Administration (EIA) estimates that residential and commercial buildings in the United States account for 39% of total energy consumption (2019). Building mechanical systems, such as Heating, Ventilation, and Air Conditioning (HVAC), refrigeration and plumbing systems are designed to deliver thermal comfort, healthy ventilation (indoor air quality – IAQ), and water to…

Explainer: Installing HVAC, Refrigeration & Line Set Insulation Outdoors

What is a Line Set? A line set is essentially a set of semi-flexible copper or aluminum tubes running from an air conditioner, heat pump or ductless mini-split unit located outdoors to the air handler in an attic. It consists of liquid (smaller) and suction (larger) tubes, wiring, and insulation. Do Line Sets Need to…

Best AC Piping Insulation

Should AC Pipe Be Insulated? AC piping insulation is a critical component of HVAC systems that utilize piping to transfer cool/cold and warm/hot fluids and ultimately deliver conditioned air to a building’s occupant spaces. The right insulation for AC lines saves energy by preventing heat gain to the refrigerants, controls condensation, protects the piping from…

Refrigeration – Aeroflex USA

Commercial and industrial refrigeration systems (piping, fittings, and vessels) typically operate in the 35°F to -100°F range. These continuous service temperatures are typically below-ambient and under constant threat of condensation and vapor drive. Additionally, hot gas defrost cycles can reach intermittent spikes of 250°F. The consequences of inadequate refrigeration pipe insulation design include saturated insulation,…

Calculation of R Value

Thermal insulation for commercial and industrial mechanical systems (piping, ducts & equipment), also known as mechanical insulation, serves to reduce heat transfer between one surface and another or a surface to the environment. The term and measurement for an insulation’s ability to reduce heat transfer is called thermal conductivity, also known as K value. Like…
