Doorbell Installation questions, answered by experts

It is possible to install a radiant barrier yourself. However, knowing how to install a radiant barrier and actually doing it are two totally different things. For example, it’s important that they be installed in a straight line but at an angle that creates a gap between the roof panels and the foil or spray. If this gap is too large or small, it won’t function as it should, and that may be hard to avoid if you’re only a novice. When in doubt, leave this job to a pro.

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Costs depend on area size, material thickness, and site preparation needs.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.
