Insulation Condensation Pictures
Condensation creates problems including mold and mildew growth which causes exposed metal to oxidize. It can lead to corrosion of decking, metal roof panels and fasteners. Wet insulation also attracts insects, causes unpleasant odors and increases health risks.
Maintaining a reasonable inside relative humidity of less than 60% is an important factor in preventing condensation and frost build up. Installing a high performance thermal insulation system using fiberglass insulation with facing will create a vapor barrier envelope and help to prevent condensation from forming.
