True Building Performance is the Capital District’s top rated insulation contractor. It’s no secret that the combination of our older houses along with cold winters and humid summers, can be a recipe for high bills and uncomfortable homes. Our staff has years of experience identifying solutions and best practices for improving efficiency, safety, and comfort. Let us provide an honest evaluation and help in creating a customized plan for your home.

"The job went great. It took two days; the first to remove and dispose of old fiberglass batts and debris and the second to do the attic work. This included: air sealing the attic, fire protection for all recessed lighting in ceiling, fire rated barrier around chimney, constructing and insulating a new hatch for access to attic, creating proper ventilation from soffits (which had been an ongoing problem) and blowing in approximately 18 inches of new cellulose insulation. The workers (four men) arrived on time, worked extremely well as a team and where very meticulous in their clean-up. I was very impressed by their professionalism and experience in completing the job."

Energy Efficiency Auditing questions, answered by experts

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

While installing your new furnace, you should consider hiring a pro to perform a home energy audit . This audit will give you a handy list of any projects you could undertake to improve your home's overall energy efficiency rating, including replacing or sealing windows and insulating the attic. These improvements can help save you money each month in utility costs.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

Yes, pros suggest units with high EER ratings for energy savings.
