A Technical Note by ECOIN INSULATION Overview Aluminum jacketing is valued for its durability and corrosion resistance; however, surface discoloration may occur due to oxidation when exposed to moisture during transportation, handling, or storage. Cause of Surface Oxidation Surface discoloration/oxidation is a superficial condition caused by prolonged contact between moisture and the aluminum surface,
Comparison & Selection Guide: Fiberglass/Rubber Foam Duct Liner vs. Duct Wrap for HVAC Insulation The core difference between these four products lies in installation location and functional priorities. For HVAC systems, the key is to match the needs of thermal insulation, noise reduction, and environmental adaptability. Here’s a detailed comparison and selection guide: I. Core Parameter
What Is the Best Insulation Material for Chilled Pipes? A Professional Guide When it comes to chilled water and refrigeration systems, choosing the right insulation material is critical. Proper insulation prevents condensation, reduces energy loss, and protects systems from corrosion under insulation (CUI). Below is a clear, expert guide based on global engineering practice and
Understanding ASTM E84 Requirements for Commercial and Mechanical Insulation Applications When discussing fire performance requirements in the North American market, the ASTM E84 (UL 723) test method is one of the most referenced standards for evaluating Flame Spread Index (FSI) and Smoke Developed Index (SDI). Many building owners, architects, and engineers rely on these values
Key Properties of Rubber Foam Insulation: Fire Rating, Moisture Resistance, and Thermal Conductivity One day, I received a call from SGS. They told me that our rubber foam insulation had been under water vapor transmission testing for 11 days, yet the instrument still detected no measurable vapor. Their equipment’s lower limit was 4.33 × 10⁻²
If you work with commercial or industrial insulation for piping, boilers, or vessels, you've likely encountered ASTM standards like C547, C592, C612, and C553. These specifications are critical for selecting materials that ensure thermal efficiency, safety, and compliance. But with similar names, how do you choose the right one? This guide cuts through the confusion.
