Tolerances of Closed Cell Elastomeric Insulation
Unlike traditional mechanical insulation materials, such as open-cell fibrous (fiberglass) and rigid closed-cell (cellular glass, phenolic, polyisocyanurate), closed cell elastomeric foam insulation is flexible and comprised of many encapsulated spheres of air within a synthetic rubber base. The manufacture of flexible elastomeric foam insulation (also known as rubber) must comply with ASTM C534 Standard Specification…
Learn MoreCalculating Insulation Thickness to Control Condensation
Preventing condensation from forming on the insulation surface of a below-ambient building mechanical system such as HVAC, refrigerant, and VRF/VRV piping is critical to the long-term performance of the mechanical system and insulation. Corrosion under insulation (CUI) can result from improper insulation thickness. Other related factors include energy efficiency, mold prevention, protection of surrounding surfaces…
Learn MoreListed & Labeled
The 2018 edition of the International Mechanical Code® added new language and requirements for duct insulation coverings (wrap) and linings (liner), including adhesives, contained within plenums. Within Section 604.3 Insulation Coverings and Linings, the new requirement states that duct insulation and adhesives must be “listed and labeled.” What exactly does this mean? Duct Insulation must…
Learn MoreWhat is GREENGUARD Gold Certification?
What is GREENGUARD Certification and why is it important? UL Solutions developed the GREENGUARD Certification program as a testing & certification solution towards improving indoor air quality for residential and commercial indoor environments. It is well documented that there can be hundreds of airborne chemicals, known as volatile organic compounds (VOC’s), present in the indoor…
Learn MoreCombustibility 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…

Learn MoreAEROFLEX®-EP is FM Approved
FM Approvals (FM), a division of FM Global, provides third-party testing and certification services. FM Approval certification differs from other well-known insulation industry fire safety test, standards, and requirements such as ASTM E84, UL 723, NFPA 90A/90B, and the International Mechanical Code® Listing and Labeling requirement. FM Approval provides commercial and industrial building owners with…
Learn MoreVRF/VRV Pipe Insulation Considerations
VRF (variable refrigerant flow) and VRV (variable refrigerant volume) systems (VRF/VRV), also known as ductless or mini-split systems, are an innovative alternative to traditional HVAC systems that deliver thermal comfort to individual occupant spaces without ductwork. System benefits include increased energy efficiency, simultaneous heating and cooling, space conservation, design flexibility, and individual user controls. Since…
Learn MoreAEROFLEX® and MRI Quench Piping
Magnetic resonance imaging (MRI) scanning machines are employed in the healthcare field for disease detection, diagnosis, and monitoring of treatment. Major MRI machine manufacturers, such as GE, Siemens, Canon, Hitachi, and Philips, use cryogens to cool magnets in MR scanners. Cryogenic gases, such as helium, are designed to be safely vented out of the building…
