Doorbell Installation FAQs, answered by experts

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important.

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency.

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.

Professionals can install a radiant barrier in a day or two, but DIY installation will take several days. The time it takes to install a radiant barrier depends largely on the size of the space and the installation method. Larger homes can take a pro two to three days to finish the job. It’s also quicker to lay foil over existing insulation.

Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.
