"My husband and I agree: Working with Voltaire Engineering was completely satisfying from beginning to end! All successful experiences start at the top, and this one was no exception. After we purchased a special deal through Angie's List, Director of Operations Dan Rosenbaum contacted us promptly and set up an appointment to visit our home. We instantly liked him; he is witty, smart and easy to talk to and just instinctively inspires confidence. He helped us to see past the obvious solutions to our various needs, and in each case we were glad we followed his advice. His electrician and painters were fabulous, too. They listened carefully to our needs and completed all tasks with true professionalism. In short, we were thrilled with every aspect of the project, including pricing. True to his company name, Dan is an enlightened professional whose problem solving approach to providing services is impressive. We loved having him and his team in our home. In fact, we have just compiled a list of additional projects and are hopeful that we can hire him again!"

"It went very well. I would highly recommend this company. They were polite and professional, as well as, highly knowledgeable about their work. The lead electrician, even gave me his personal cell phone number so I could contact him if anything of concern happened while they were working and after hours. The job took two days with the weekend coming between them."

"i was very impressed with the professionalism of the assessment and the comprehensiveness of the report. As followup they came and discussed the report and explained any questions. I submitted the report to the Governors Energy Office (GEO) for partial reimbursement (rebate) and will personally address air infiltration and other problem areas noted in the report. I would highly recommend Voltaire for home energy audits."

Energy Efficiency Auditing questions, answered by experts

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.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.
