"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

Yes, products made from renewable resources and with reduced chemical impacts.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.
