Doorbell Installation questions, answered by experts

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.

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.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.
