Doorbell Installation questions, answered by experts

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.

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.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.
