Decibel Dropp & Noise Reduction Coefficients For Material Combinations

Material manufacturers are required by law to publish Material Safety Data Specification (MSDS) sheets for their products. The MSDS sheet consists of the chemical and physical properties of a particular material like fiberglass or mineral wool. In addition to the MSDS, companies manufacturing materials that target the sound-reduction market often publish sound-reduction coefficients for their...

The Newton-Laplace Equation & Speed of Sound

In order to determine the speed of sound in a particular medium, we need to know the medium’s elastic properties and its density. A medium’s elastic properties determine whether or not the medium will deform or lose its shape due to external forces. Sound travels faster in mediums with high elasticity and minimal deformity – like steel. Sound travels more slowly in less rigid mediums that deform...

WHY YOUR INSULATION JACKET DOESN’T FIT

In the business of custom mechanical insulation, the right fit is critical. Even with the use of the least conductive, most space-age synthetic fibers, insulation covers only work as well as they fit. Loose insulation blankets simply do not work as efficiently as a perfectly tight jacket. Yet, if an insulation jacket fabricator errs by constructing a jacket that is too tight, the client may not...

Why Traditional Hard Insulation Is Costing You Money

A Connecticut university used to have a serious energy loss problem. One example of this was a valve in the mechanical room. Although hard insulation was dug out to form the shape of the valve, it still left the valve bonnet exposed, leading to significant heat loss. The temperature of the valve bonnet was 224 degrees. After installing a removable insulation cover, the surface temperature was...
