Increasing Attic Insulation in Belleville, IL: UnCovering a Problem

Never insulate an attic without thoroughly air sealing and fixing all the things you are about to bury like the can lights, space around the chimney, the myriad of pipe and wire holes, etc. Many “insulation contractors” ignore these important areas all the time: they just cover them with insulation. The air leaks up through all these unsealed gaps and holes and right up through the insulation. Dr. Energy Saver St. Louis seals up any penetrations, properly vents fans and brings your insufficient insulation up to and beyond industry standards.

Belleville, IL Garage Insulation

Belleville, IL Garage Insulation Belleville, IL Garage Insulation

The attic area above the garage in this Belleville, Illinois home suffered from air leaks and lacked any form of insulation.  Lacking air sealing and insulation in the attic allows conditioned air from the living space below to leak up into the attic, essentially heating or cooling the attic space and wasting energy.  It also allows unconditioned air from the attic—especially in the summer—to radiate or seep into the living space below, creating drafts and uncomfortable temperatures.


Dr. Energy Saver air sealed and insulated the attic above to effectively keep the outside temperature outside, and the inside temperature inside.  These homeowners are now living comfortably and efficiently at home.

While vaulted ceilings can add aesthetic appeal to your home, they are not always the easiest area to properly insulate. Without proper insulation damming, the blown insulation near the top of the ceiling’s peak can easily settle and fall down to the lower end of the ceiling. Dr. Energy Saver St. Louis can properly dam and insulate your vaulted ceiling to ensure your blown attic insulation stays put.

Job Stories From Belleville, IL
Tru-Soft Cellulose Insulation Saves On Energy Bills in Belleville, IL

William H.’s home in Belleville, IL was never quite comfortable enough. It was difficult to keep it at the right temperature during the summer and winter despite blasting the air conditioning or heating. All of that extra heating and cooling was costing him in energy bills as well so he called Woods Basement Systems and Dr. Energy Saver for a free home energy audit. After inspecting the home with the thermal imager to find energy leaks, Design Specialist Peter Newell found that the attic insulation was inadequate and recommended blow in cellulose insulation.

Woods blanketed the attic with blown in cellulose insulation. Tru-Soft Cellulose insulation is the green insulation choice. It’s made from recycled newspaper material that is treated with a natural borate solution that makes it resistant to fire, mold and pests. Homes insulated with Tru-Soft cellulose use around 15 to 30 percent less energy than homes insulated with fiberglass batts.

William is glad that his home is finally comfortable and the additional insulation will end up paying for itself by saving him on energy bills.

Home More Energy Efficient in Belleville, IL

The enviroment was important to this homeowner and they wanted to help out in any way they could and shave off some numbers from their energy bills.  After calling Dr. Energy Saver St. Louis they found that blown in cellulose insulation would help them improve the thermal boundary between the attic and the conditioned space.  But before this could occur, the attic needed to be air sealed so she could stop losing air.  Now her home is more energy efficient for her and the environment.

Belleville, IL Home Upgrades into More Energy Efficient

Ben and Melanie were unhappy with the humidity of their home in the summer and the drafts and the cold in the winter.  Not only did they want to improve the conditions of their home, but they wanted to make it more energy efficient as well.  After calling Dr. Energy Saver St. Louis and getting a Complete Home Check-up they discovered how much energy they were losing.  Dr. Energy Saver sealed up their home with spray foam, installed vents on the roof, and filled the attic with better insulation to create a better thermal boundary.  Today, Ben and Melanie are living more energy efficient and more comfortably.
