Doorbell Installation questions, answered by experts

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. 

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.

Insulating your ducts offers several benefits, including:

  • Improved energy efficiency: Duct insulation prevents energy losses, reducing heating and cooling costs.

  • Cost savings: Lower energy bills make insulation a cost-effective investment.

  • Environmental benefits: Enhanced efficiency reduces your carbon footprint.

  • Consistent comfort: Insulated ducts help maintain a stable indoor temperature.

  • Better indoor air quality: Reduced allergens and pollutants improve air quality.

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

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