"The entire process was seamless, from my initial contact with Jon until the project was completed. Jon was always a telephone call or an email away, quite assessible, knowledgeable and professional about the solar industry and financing institutions. My experience was a pleasant one and I've seen a significant reduction in my monthly utility bill."

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.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.
