Employing moisture-management tactics in commercial-building wall-assembly design to increase thermal efficiency and minimize the potential for indoor-air-quality- (IAQ-) threatening mold growth has become popular in recent years. Another important tactic for mold prevention is ductwork insulation. This article will discuss the role fiberglass duct insulation can play in mold prevention.
Preventing Mold With Fiberglass Duct Insulation
Condensation occurs when duct-surface temperature equals or is less than the dew point. When condensed moisture mixes with dust or dirt, mold and microbial growth occurs.
