Can fiberglass insulation cause mold?
We all know that mold in your home can be a problem. By nature, fiberglass is designed to trap dust and airborne mold. When that insulation is exposed to moisture, mold can grow on the paper backing on the fiberglass. Cellulose insulation is treated with fire-retardants, and those chemicals are mold-resistant. However, the cellulose can absorb water with mold spores. When the wet cellulose absorbs this water, it can transfer moisture to the ceilings, drywall, and wooden structures. As a result, mold growth can spread and decay these spots in your attic.
Does fiberglass lose its R value?

When cold air gets trapped inside a wall, the warm air will cause it to condensate, thus getting the insulation wet. Cold air usually gets in through siding or window and door framing/casing. If there are too many air gaps, this problem will grow steadily worse, so definitely check for those if your mission is to minimize condensation, and if you find any, make sure to seal up those gaps.
