"They are the answer to lower energy costs and better comfort. In my area, home builders applied minimum standards when it came to insulation. Performance Energy fixed it and made it right. We could tell the difference overnight. Plus, they file all gov't rebates for you. Very grateful."

"Awesome experience. Purchased home with open crawl space that was deteriorated with hanging insulation, and breeding ground for rodents and waste. Researched crawl space options and interviewed several companies to compare. Greg was honest, informative and provided an option that encapsulated the raised crawl space, complete with dehumidifier and thick vapor barrier. He promised to come by annually to check and make any necessary adjustments and stood by his word - we had the project completed in 2015 and he came back in 2016 adding some sealer to small gaps that occured and will be scheduled him again to return soon for 2017 service. VERY happy we completed - the house smells much better (they disinfected underneath and spent time ensuring joists were clean), air quality and comfort level is greater and greater peace of mind with rodent exclusion. Would HIGHLY recommend Greg and his crew"

Insulation FAQs, answered by experts

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

The lifespan of crawl space insulation depends on how well you maintain your insulation and the type of insulation. Fiberglass will need replacing every 15 to 20 years on average if you don't have a vapor barrier in place. If you do have vapor barriers in place, then your insulation could last much longer. Spray foam insulation can last anywhere from 80 to 100 years. 

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.

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.
