"After getting quotes from a few companies, we chose ThermaCore Insulation for our attic insulation replacement and are very happy we did. The crew was hardworking, professional, and paid attention to the details. They removed the old insulation, cleaned everything up, and installed the new insulation efficiently. The house feels more comfortable, especially during the afternoon heat. The entire process was smooth and stress-free. Highly recommend ThermaCore Insulation to anyone looking to improve their home’s comfort and energy efficiency."

"Fantastic. Always on time and very friendly. I love knowing my attic is clean, sealed and insulated. I have actually stopped sneezing!!"
You will never look at your home the same when you see what "Stack and Draft” is doing to waste energy.
Window Replacement
When you heat your home the hot air rises and begins to “Stack” pressure on the ceiling until it finds an escape route around the many holes hidden in the construction where walls and light fixtures meet the ceiling. The hot air leaking creates a draft by pulling in cold air from outside.
Window Replacement
The more you turn up your thermostat, the more "Stack" is applied to the ceiling, accelerating the icy cold "Draft" right behind it.

"Old shake roof was removed, new insulation added, plywood base with roof paper cover. Then tiled over raised battens. New gutters and downspouts. Dry rot repairs and painting of new surfaces.The whole process took four days. The bid and contract were presented very thoroughly, each item of work detailed and priced. Many choices. The work crews were very pleasant. The work was done in a set order and a company rep would call to inform of the next step and when it would happen. At the conclusion of each days work the property was cleaned and as tidy as possible given the nature of the project. When finished, a company rep inspected the job and checked for any needed corrections. All in all, an outstanding contractor to work with."

Insulation questions, answered by experts

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

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 primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

Yes, you should insulate your copper pipes to help regulate their temperature. Well-insulated copper pipes will be protected from freezing and can conserve energy by keeping hot water warm for longer. Foam rubber insulation tubes are the best pipe insulation to prevent freezing since they fit tightly around the pipes while still maintaining some flexibility.

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.
