Q: Is a moisture or vapor barrier necessary?

• <div><p>A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage.

Q: Is fiberglass insulation safe for my home?

• <div><p>While fiberglass is dangerous to work with, it&rsquo;s a perfectly safe material once it&rsquo;s installed.

Working with a professional insulation company can mitigate these risks.</p></div>

Q: Do I need to air seal my attic before installing insulation?
