Key Considerations for Refrigerant Piping Insulation
Refrigerant piping insulation is crucial for refrigeration systems. Refrigeration systems, also known as below-ambient systems, vary by application (commercial and industrial), temperature requirements (high & low), refrigerant types (traditional and natural), and operating environments. Common refrigeration system applications include supermarkets, cold storage, food processing, beverage dispensing lines, ice rinks, morgues, laboratories, chillers, data centers, and…Learn More
A Proven Solution for Hydronic Pump Insulation
Looking for a solution for hydronic pump insulation? Let’s start with hydronic pumps. Hydronic heating and cooling systems circulate water through a building’s piping systems to deliver heating and cooling for occupant comfort. These systems are basically composed of an energy source, such as a boiler, water heater, or chiller, and electronically-powered pumps that move…Learn More
Guide to Mold Resistant Insulation
Mold resistant insulation is an important consideration to prevent the dangers of mold. Molds belong to the fungi kingdom, and unlike plants, they lack chlorophyll and must survive by digesting plants and other organic materials. Molds generate tiny spores to reproduce, and these spores are ever-present in both indoor and outdoor air currents. When mold…Learn More
Why Use Plumbing Insulation?
Wondering why to use plumbing insulation? Plumbing piping systems, commonly known as domestic hot and cold water service systems, convey water to fixtures and equipment for various purposes in residential, commercial, and industrial buildings. The most common concerns with plumbing systems that should be addressed during the design stage include heat loss, condensation control, freeze…Learn More
Differences Between NFPA 90A and 90B
Two applicable fire safety standards for HVAC systems in the built environment are NFPA 90A and NFPA 90B. The National Fire Protection Association (NFPA) is a global organization established in 1896, primarily known for code and standard development, that is dedicated to eliminating death, injury, property, and economic loss due to fire, electrical, and other…Learn More
Why Closed-Cell Flexible Elastomeric Foam Insulation on Cold Systems?
Mechanical insulation on cold (below-ambient) mechanical systems such as chilled water, brine and refrigerant piping/equipment is an important component to ensure that a project team’s basis of design (BOD) and owner project requirements (OPR) are satisfied…Learn More
What is HVAC Pipe Insulation?
What is HVAC 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). Heating, Ventilation, and Air Conditioning (HVAC) systems are designed to deliver thermal comfort and healthy ventilation (indoor air quality – IAQ) to building occupants. The EIA…Learn More
Demystifying ASTM E84 25/50, UL 723 and NFPA 255
Currently, confusion exists in the U.S. mechanical insulation industry (closed cell elastomeric foam pipe, duct, and equipment insulation to be specific) about the differences between well-known fire behavior safety standards such as ASTM E84 25/50, UL 723, and NFPA 255. Ever since the destructive building fires throughout the United States dating back to the early…Learn More
What is Flexible Elastomeric Insulation?
Closed cell elastomeric insulation has been available in the United States since the 1950s. It’s also known as flexible elastomeric foam (FEF) insulation, UV resistant refrigerant line insulation, flexible elastomeric pipe insulation, HVAC refrigerant line insulation, UV resistant refrigeration pipe insulation, HVAC pipe insulation, AC refrigerant line pipe insulation, HVAC refrigerant pipe insulation, AC…Learn More
How to Choose the Right VRF and VRV Pipe Insulation
Choosing the right VRF and VRV pipe insulation system can deliver countless benefits. Although variable refrigerant flow (VRF) or variable refrigerant volume (VRV) systems have been available in other countries for about three decades, this HVAC technology has only been available in the U.S. market for a decade or so. In that relatively short period…Learn More
