Insulation questions, answered by experts

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.
