Air flow, heating and cooling, and external environmental conditions will over time lead to the breakdown of HVAC components. One of the more delicate components of an HVAC system is the insulation. Internally lined fiberglass insulation breaks down when exposed to each of the above mentioned causes. This can lead to friable fiberglass particulates traveling into the air flow, contaminating work environments, causing respiratory issues, and more. If it is determined that repair of the insulation is necessary, Advanced can perform internal lining repair.
