Q: Are there any safety concerns with fiberglass?

• <div><p>Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don&rsquo;t pose risks for fiberglass exposure because they're fully encased in polymer cladding.</p></div>

Q: How do you insulate a stone house?

• <div><p>Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don&rsquo;t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls. </p></div>

Q: How thick should floor insulation be?

• <div><p>The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn&rsquo;t prevent ventilation, it can be as thick (or thin) as you need.</p></div>
