Combustibility of Mechanical Insulation
Fire protection design for commercial buildings is critical to the life safety of building occupants and the building itself. Fire codes, fire protection standards, and building codes reference various terms such as fireproof, fire resistance, flame retardant, noncombustible, and many more. This technical bulletin will address the combustibility of construction materials, including mechanical insulation. The…

Sweetwater, TN – Aeroflex USA is pleased to introduce AEROFLEX Breathe-EZ™ fiber-free EPDM closed-cell elastomeric duct insulation to the North American market. Applications include duct liner and wrap for energy conservation, condensation control, and acoustic attenuation. AEROFLEX Breathe-EZ™ complies with the International Mechanical Code’s requirement for duct covering and linings contained within building plenums to…
Learn MoreWhat is CAN/ULC-S102?
Underwriters Laboratories of Canada (ULC Standards) is accredited by the Standards Council of Canada (SCC) to develop and publish standards for building construction, thermal insulation products, and much more. The SCC established the National Standards of Canada (NSC), in cooperation with ULC. CAN/ULC-S102 (CAN/ULC) is an example of a specific standard developed and published under…
Learn MoreThe Important of a Perm Rating
An often overlooked technical performance characteristic of mechanical pipe and equipment insulation is water vapor permeability (WVP). ASTM International defines WVP as “the time rate of water vapor transmission through unit area of flat material of unit thickness induced by unit vapor pressure difference between two specific surfaces, under specified temperature and humidity conditions.” A…
Learn MoreDuct Insulation Adhesives
For lining and wrapping sheet metal ductwork, Aeroflex USA offers AEROFLEX Aeroseal, REF 1520TM, and Aeroseal LVOCTM adhesives for the installation of AEROFLEX Breathe-EZTM EPDM Duct Insulation. Aeroflex USA does not offer an aerosolized spray adhesive for the installation of AEROFLEX Breathe-EZTM. We recommend that duct fabricators and insulators check with preferred adhesive manufacturers for…
Learn MoreNesting Chart (Copper) for AEROFLEX EPDM™ 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…
Learn MoreInsulation Adhesives and Austenitic Stainless Steel
Austenitic stainless steel is often specified for high-performance industrial applications. Like other metallic piping types, such as copper and iron, stainless steel is susceptible to a type of corrosion known as external stress corrosion cracking (ESCC). With system cycling temperatures in the 140°F to 250°F range, the lower temperatures can generate moisture and the upper…
Learn MoreEnergy Standards and Codes | Mechanical Insulation
Energy, whether it be traditional or clean, is a precious resource, drives economies, and meets a basic human need for thermal comfort while powering our lives. The U.S. Energy Information Administration’s 2018 Commercial Buildings Energy Consumption Survey estimates that commercial buildings consume 39% of total energy in the United States[1]. There are two model energy…
Learn MoreInspecting AEROFLEX® EPDM™ Closed-Cell Elastomeric Foam Insulation
When conducting a post-installation inspection of AEROFLEX® EPDM™ mechanical insulation, it is critical not to physically damage the insulation. When mechanical impacts, such as fingers/hands, tools, and foot traffic break the skin of the insulation surface, the following unintended consequences can occur: R-value reduction Energy loss Condensation (dripping on objects below) Corrosion under insulation (CUI)…
Learn MoreAsbestos-Free
The purpose of this technical bulletin is to confirm that ALL Aeroflex USA AEROFLEX EPDM™ closed-cell elastomeric insulation and accessories (adhesives, coatings, tapes, insulated pipe supports, and talc) do not contain asbestos.
