"I was looking to improve the energy efficiency of my existing home and opted to change out old blown in insulation for foam spray insulation. I took time to investigate cost and options and requested quotes from various companies. I am a family physician and if you know doctors, we donâ t usually jump the gun unless we are well informed. Brav Co Energy Solutions representative came to evaluate my home for a quote. I was impressed by his knowledge of the product. He took measurements (which none of the other companies had done), provided a pamphlet of the actual foam product that would be applied (I researched it and it does have 5 star reviews) and also sent the men who would be doing the insulation to inspect my attic and ensure the foam spray insulation could be completed as I had requested. I have low attic ceiling space and there were very snug corners that I had been told would not be reachable by other companies. Brav Co Energy Solutionâ s men came, inspected and informed me their equipment would reach every corner of my attic. After a full inspection, I received a quote which was comparable to the other companies and given the thoroughness of the inspection that was done by Brav Co Energy, I opted to go with their team. I was amazed at their efficiency to remove all the old insulation and debri. My attic appears cleaner allowing visibility of all my air conditioning duct work, wiring, and plumbing. The foam insulation (and yes, I physically went up in my attic and inspected it, from corner to corner) is seamless and encases the full attic space including the attic space above my garage and above a very tight front room. Brav Co Energy also provided a warranty on the foam installation. I can feel the difference in the cooling and heating of the house- the unit does not turn on as often and does not sustain on. I get weekly usage emails from my electricity company and this month I am predicted to considerably save on electricity costs. I highly recommend Brav Co Energy Solutions and will keep them in mind for future homes I purchase."

Insulation FAQs, answered by experts

Yes, you should insulate behind shower walls. Insulating helps prevent heat loss, which keeps the shower or tub from getting too cold and helps maintain a comfortable temperature in your bathroom. Additionally, proper insulation and air sealing can help prevent wall rot and moisture buildup. It is recommended to use a high R-value rated foam insulation combined with a vapor barrier.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

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.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.
