Insulation questions, answered by experts

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.

There are many ways to keep your house cool without central air. In fact, ductless mini-split AC systems are a solid alternative to central AC for situations when you can’t install ducts in your home. If you’re looking for a more budget-friendly cooling solution, consider using window AC units or portable air conditioners.

Each insulation type has its own R-value, so you’ll want to weigh the pros and cons of your materials when deciding which one will give you the best value. Energy.gov recommends you choose a pipe wrap that’s at least one inch thick. The International Code Council (ICC) suggests choosing a pipe material with an R-value of at least 3.

An insulated garage benefits from roof vents to ensure proper ventilation and prevent moisture buildup. Insulation can trap moisture in the garage, especially during temperature fluctuations, and roof vents play a crucial role in expelling the moisture in the air. Including roof vents promotes air circulation, preventing condensation and enhancing overall air quality.
