Doorbell Installation questions, answered by experts

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

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.

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.
