Do vapor barriers cause mold?

One of the more common problems with crawl spaces that do not have a crawl space vapor barrier system is that they create high moisture levels, which may result in mold growth – as dampness creates the ideal environment for mold growth.

What is the difference between vapor barrier and moisture barrier?

Moisture barriers function to help in preventing water from entering inside of the wall cavity. On the other hand, vapor barriers basically prevent water vapor from the interior of the house to filter through the wall and condense on the warm side of the insulation.

Can fiberglass insulation touch electrical wires?

It is perfectly safe for household insulation to touch wires provided the wires or cables are electrically insulated. There also are techniques to make insulation fit better around wires. However, under no circumstances should thermal insulation make contact with live uninsulated wires and cables.

Can electrical junction boxes be covered with insulation?

β€œJunction boxes can be covered by insulation in such a manner that it can be removed without damaging it to access the box. Foamed-in-place insulation isn’t removable and therefore not permissible.”
