"ThermaCore Insulation did a great job from start to finish. They removed our old insulation, installed new insulation, completed sanitation, and did rodent proofing as well. The crew was professional, respectful, and explained everything clearly. Overall, I’m very happy with the service and would recommend them to anyone needing insulation or attic work."

"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

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

One of the biggest disadvantages of glass garage doors is that they are not the best at insulating your garage. In the summer, heat can enter through the glass, while in the winter, heat can escape through the glass, increasing your electricity and gas bills as you crank up your HVAC unit. You can help mitigate the poorer insulation by investing in insulated glass and insulating your garage.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

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.
