"They recommended that I did not need roof insulation. Very honest and professional opinion and advised if they performed the insulation (since he determined my insulation was very good), I would not realize any benefit. I really appreciated that honest evaluation. Would recommend them to anyone needing insulation; they are not a fly by night firm and in explaining what they do and how they do it, separate themselves from the rest of the pack."

Insulation FAQs, answered by experts

Yes, you should insulate behind shower walls. Insulating helps prevent heat loss, which keeps the shower or tub from getting too cold and helps maintain a comfortable temperature in your bathroom. Additionally, proper insulation and air sealing can help prevent wall rot and moisture buildup. It is recommended to use a high R-value rated foam insulation combined with a vapor barrier.

Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.

It improves energy efficiency, reduces noise, enhances indoor comfort, and prevents drafts by filling wall cavities.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.
