How does insulation impact energy efficiency and reduce utility costs?
Insulation improves energy efficiency by preventing heat from escaping a building, thereby maintaining a stable indoor temperature and reducing the need for excessive heating or cooling, which in turn lowers utility costs by minimizing the strain on HVAC systems; essentially, proper insulation means your heating and cooling systems don’t have to work as hard to maintain a comfortable temperature, resulting in lower energy consumption and smaller bills
What are the benefits of spray foam insulation compared to other types?
Compared to other insulation types, spray foam insulation stands out due to its superior air sealing capabilities, high R-value, ability to fill gaps and crevices in complex areas, moisture resistance, and potential for soundproofing, effectively reducing heat loss and improving energy efficiency in a home while also providing a barrier against drafts and allergens.

Yes, as of 2023, the primary incentive for installing insulation is a federal tax credit, allowing homeowners to claim up to 30% of the cost of insulation materials, with a maximum credit of $1,200 per year, under the “Energy Efficient Home Improvement Credit” provision of the Inflation Reduction Act. Also utility rebates
How often should insulation be replaced or upgraded?
Insulation should typically be replaced or upgraded every 15–20 years, but the exact timing depends on several factors, including:
Type of insulation:
The type of insulation material used can greatly affect how long it lasts. For example, spray foam insulation can last up to 80 years, while cellulose insulation typically lasts 15–30 years.
What should I expect during an insulation inspection?
During an insulation inspection, you can expect the inspector to:
Check the R-value: Ensure that the R-value of the insulation meets or exceeds the building plans. The R-value indicates how well the insulation blocks heat.
Verify installation: Check that the insulation is installed properly and completely fills the joist cavity. There should be no gaps between the insulation and the subfloor.
Assess ventilation: Evaluate the quality and effectiveness of the ventilation system.
Check for moisture and mold: Look for signs of moisture issues and mold growth.
Inspect for pests: Check for signs of pest infestations, such as bats, rats, mice, and bugs.
Use specialized equipment: Use infrared cameras to identity areas where air leaks are occurring.
(You can also check your insulation yourself by:
Removing the outlet cover and shining a flashlight into the crack around the outlet box.
Checking outlets on all floors, as well as old and new parts of your home.
Touching floors, ceilings, and walls to see if they feel dry and warm. External walls should feel)
