Elastomeric Foam Insulation: A Complete Guide To The Benefits Of Elastomeric Insulation

Elastomeric Foam Insulation: A Complete Guide To The Benefits Of Elastomeric Insulation

Although closed-cell elastomeric foam insulation has been commercially available since the 1950s, some confusion still exists about the performance properties and benefits of this insulation type. That said, closed-cell elastomeric foam insulation has proven to be one of the top choices for cold (below-ambient) mechanical pipe and equipment applications. The purpose of this post is…

Considerations to Prevent External Stress Corrosion Cracking with Austenitic Stainless Steel

Considerations to Prevent External Stress Corrosion Cracking with Austenitic Stainless Steel

One of the greatest threats, sources of system failure, and maintenance/replacement costs
to mechanical systems is corrosion to the metallic surfaces of piping and equipment.

What to Look for in HVAC Refrigerant Pipe Insulation

What to Look for in HVAC Refrigerant Pipe Insulation

HVAC refrigerant pipe insulation is a critical component to a well-designed refrigeration system to achieve long-term performance and life cycle costs for building owners. Refrigeration systems are demanding and generally operate continuously with the potential for downtime to be minimized. While every refrigeration system has its own set of unique requirements, they all have two…

Specifying UV-Resistant Refrigerant Line Insulation

Specifying UV-Resistant Refrigerant Line Insulation

The need for UV-resistant refrigerant line insulation is common for installations on building exteriors, such as rooftops, to convey refrigerants between large roof-top HVAC systems and interior equipment to provide conditioned air to the building’s occupant spaces and equipment. U.S. commercial energy codes and standards, such as ASHRAE 90.1 Energy Standard for Buildings Except Low-Rise…

How to Choose the Best Plenum-Rated Pipe and Duct Insulation

How to Choose the Best Plenum-Rated Pipe and Duct Insulation

Plenum spaces in buildings are designed to discreetly house building systems such as HVAC equipment & return airflow, pipe runs, and digital cables. Although air plenums are typically out-of-sight, typically located above ceiling grids or in under-floor systems, mechanical design and plenum-rated pipe and duct insulation are critically important to ensure the safety of building…

Pipe Hanger Supports Critical to High-Performance Insulation System Design

Pipe Hanger Supports Critical to High-Performance Insulation System Design

A common failure point of mechanical insulation on cold (below-ambient) piping systems is
at the hanger locations due to compression of insulation subjected to inadequate support
or no insulation at all (thermal bridging)

Nesting (Layering) Chart for Aerocel® Pipe Insulation

Nesting (Layering) Chart for Aerocel® Pipe Insulation

Certain HVAC, refrigeration and plumbing pipe insulation applications require more than a single layer of Aerocel® EPDM flexible elastomeric insulation to control condensation in demanding conditions such as a cold line temperature in a hot and humid operating environment. Our “nesting” chart offers the best fit for installing an additional layer (sleeving) over the most common copper and iron pipe insulation sizes. It’s important to note that Aeroflex USA tests 1”, 1-1/2” and 2” thicknesses for ASTM E84 25/50 flame/smoke compliance. We do not test other thickness combinations, and thicknesses over 2” will not pass ASTM E84.

Key Considerations for Refrigerant Piping Insulation

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…

A Proven Solution for Hydronic Pump Insulation

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…

Guide to Mold Resistant Insulation

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…
