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.

Learn MoreConsiderations 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
HVAC refrigerant pipe insulation is a critical component of 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…
Learn MoreSpecifying 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…
Learn MoreHow 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 (i.e. plenum rated insulation) are critically important to ensure the safety of building occupants and…
Learn MorePipe 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

Nesting (Layering) Chart for AEROFLEX® Pipe Insulation
Certain HVAC, refrigeration and plumbing pipe insulation applications require more than a single layer of Aeroflex® 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.

Learn MoreHeat Tracing Systems with AEROFLEX EPDM™ Closed Cell Elastomeric Insulation
Heat tracing systems, typically composed of electrical tapes & cables, are commonly installed directly on piping systems to increase or maintain the line temperature of pipes and vessels with low or no flow, ultimately in an effort to provide freeze protection.
