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

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.

Audits typically take 2-4 hours, depending on the property size and energy systems.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact.
