Listen to what our customers have to say about us…

“After 30 years of doing business with Don Barnett and Great Southern Insulation Corp. I can, without reservation, recommend them to anyone requiring their services. Over the years we have called on Great Southern to perform in many different areas related to soundproofing, from purchasing materials to complicated fabrication of generator enclosures, and other difficult and extremely customized installations. They have always performed in a timely manner, with quality craftsmanship and in a serious business like way. I highly recommend them to anyone.”

“GSI custom built a sound/heat insulation shield for my generator on a 92 foot motor yacht named Pixel. I took it back twice to have him change a couple things, because we did some changes to the boat which caused clearance problems with the shield. Don was more than happy to change it for me at no extra cost. It is nice dealing with someone that stands behind his work. It is super quiet and the temperature of the engine room is about 40 degrees cooler.  Without reservation I would recommend him to others.Thank you Don.”
John Flynn M/Y Pixel – Ft. Lauderdale, FL

“GSI has built numerous sound shields for our line of generators. They look good, work well, and are easy to remove and install. We continue to use them and would recommend them.”
