Doorbell Installation questions, answered by experts

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

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.

Yes, they address underlying issues, providing long-term seals and energy savings you might need help to achieve.

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.
