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 installations include soundproofing options?

Q: Is R13 or R30 insulation better?

• <div><p>R-30 insulation is better for higher thermal resistance, but whether it&rsquo;s &quot;better&quot; depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.</p></div>
