Can too much insulation cause mold?
Moisture can cause mold as well as damage to the building materials, and improperly installed insulation can be the culprit. … If the moisture gets trapped and the insulation gets wet, it lessens its thermal value in addition to creating a potential mold problem.
What are the problems with cavity wall insulation?
Incorrectly installed cavity wall insulation causes water to seep into a property’s walls, causing structural problems and damp patches that may also manifest into mould.
Is it better to insulate attic ceiling or floor?

What is the best way to insulate under a wooden floor?
Answer: Ideally a fibrous insulation such as mineral wool or sheep’s wool performs best between timber because it will take up thermal movement and cut down air movement around the insulation. ‘Thermal bypass’ affects performance, so cutting out draughts is preferable.
Does insulation cause damp?
Why can insulation cause damp? As you’ll know, insulation is designed to slow down heat transfer, keeping warm air in and cold air out. … If insulation means this water vapour cannot escape through walls or ceilings, it sinks into the fabric of the building, or its contents.

Should you insulate under your floors?
Insulating under the floor will prevent drafts from entering via the gap between the floor and the ground. One tactic is to place rigid insulation panels between the floor joists. The contractor would need to cut the panels to fit tightly, and caulk the spaces in between the insulation and joists.
