When it comes to commercial HVAC systems, fiber glass insulation is a sound solution for a quieter work environment.

Fiber glass insulation greatly reduces the transmission of HVAC equipment and air flow-generated noise through the duct system, and also reduces noise transmitted from one room to another through the ducts.

A recent NAIMA (North American Insulation Manufacturers Association) study also found that an insulated duct system can save up to four times more energy than bare sheet metal ducts. Here are a few more sound solutions for noise control:

• Insulate heating and air conditioning ducts by using fiber glass duct board or by wrapping or lining the ducts with fiber glass insulation.
• Install thick carpeting and padding to help reduce impact sound.
• Caulk around windows and use weather stripping at the bottoms of your exterior doors.
• Use solid wood or mineral core doors where privacy is demanded.
• Install acoustic ceiling panels, double or triple pane glass or storm windows, all of which can help reduce sound.

Think condensation control

Controlling moisture in HVAC duct systems is an important indoor environmental issue in buildings. Fiber glass insulation products minimize condensation on the interior and exterior of duct surfaces and exterior surfaces of piping. They also reduce the chance for microbial growth in the duct system and other moisture-related building damage such as corrosion and stained ceiling tiles.

Fiber glass duct liner, duct wrap, and duct board will minimize the opportunity for condensation on ductwork, while proper thickness of fiber glass pipe insulation will reduce condensation on piping, minimizing the potential for microbial growth.
