Insulation questions, answered by experts

Yes, energy-efficient homes are increasingly desirable in the market.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

While freezing pipes are less of a concern in warmer climates, pipe insulation can still be beneficial because it helps prevent condensation on cold water pipes, reducing the risk of moisture-related issues like mold growth. It also helps maintain water temperature, reducing the energy needed to heat and cool the water, which can ultimately lower your utility bills.

As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces.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.
