HVAC manufacturers face a real dilemma. On one hand, today’s discerning consumers are extremely sensitive to environmental sound levels. But on the other hand, the large, flat surfaces of many HVAC products are natural sound amplifiers. Silencing your products with premium materials and add-on treatments represent add-on costs while often creating manufacturing and assembly issues.

MSC offers a better alternative with a series of unique material solutions that damp annoying noise and vibration directly at the source and offer premium appearance without premium cost as a bonus.

MSC Quiet Steel^® is a unique Noise, Vibration, and Harshness (NVH) damping material that uses an engineered viscoelastic layer laminated between two sheets of steel to meet application-specific damping, temperature, stiffness and operating environment needs. Quiet Steel^® is widely used in the HVAC industry for both mechanical components such as fan and motor mounts, and for sound-deadening enclosures. It can be supplied with a broad range of surface treatments including paint, one or two-side electrogalvanizing, and even MSC’s exclusive ElectroBrite® faux-stainless surface in a variety of shades and colors.

MSC Quiet Aluminum^® has the same Noise, Vibration, and Harshness (NVH) damping performance as MSC Quiet Steel^® but with only a fraction of the mass. Like Quiet Steel^®, Quiet Aluminum^® uses an engineered viscoelastic layer laminated between two sheets of aluminum to meet application-specific damping, temperature, stiffness and operating environment needs. It can be supplied as continuous coil or blanked sheets with a variety of coatings from forming lubricants to pre-paint.

MSC MagnaDamp^® offers the damping benefits Quiet Steel^® in an easy-to-implement magnetic package. Available in coil and sheet, in a variety of material thicknesses, it is an excellent way to address resonances or vibrations that are transmitting through the HVAC equipment case.
