St. Peters, MO Attic Insulation and Air Sealing Achieves R-Value!

Air sealing and attic insulation in the Knee Wall of this St. Peters, MO home included: three inches of spray foam insulation to stop air transfer and achieve an R-18.

Before we arrived, the knee wall was insulated with only a piece of batt insulation---and without proper air sealing, batt insulation in an attic acts very similarly to a filter in a HVAC system...air passes right through it!

Insulating Attic Hatch in St. Peters, MO

The average attic hatch is usually poorly insulated, if insulated at all. While some homeowners may attempt to insulate this hatch area with a bat of fiberglass insulation, this is not the best way to air seal or insulate it. Air transfers right through the bat much like air passes through a furnace filter. Dr. Energy Saver St. Louis air seals and insulates attic hatches with our exclusive SilverGlow insulation, which insulates the hatch to an R-20. Air cannot pass through the SilverGlo insulation---coupled with an air seal using one-part foam, the attic hatch area is now sealed tightly.

The detail between the foundation wall, the sill plate, the rim joist, and the sub flooring allows for significant air leakage from the outside...especially when pipe wire penetrations are added.  The cantilever will have much more air leakage for that there is more room for air to leak through. It is also the rim joist area that is often poorly insulated. Even when your rim joist is insulated with fiberglass bats, the outside air will still leak in through the bats, because this form of insulation acts as a filter. Spraying expanding foam insulation on the inside surface of the rim joist, to cover the sill plate down to the top of the basement wall, not only seals all air leaks very effectively, but it insulates as well.

Job Stories From Saint Peters, MO
Providing More Comfort in St. Peters, MO

Matt found his home to be very uncomfortable.  He wanted to get this under control so he called Dr. Energy Saver St. Louis.  They came to Matt's house and performed a Home Energy Audit.  The Certified Building Anaylst looked at the home and found that Matt was losing air through his attic.  Dr. Energy Saver air sealed the attic to stop exfiltration of conditioned air into the attic.  Then they filled the attic with blow loose-fill cellulose insulation to improve the thermal boundary between the two spaces.  Now, thanks to Dr. Energy Saver St. Louis, Matt's home is much more comfortable.

Sustaining Heat in Wentzville, MO Basement

James and Betty were unhappy with the coldness and their basement, especially in the winter.  They planned to live in this house forever, but decided that they didn't want to live with this problem forever.  Dr. Energy Saver came to their home and saved their basement by sealing it with spray foam.  Now the basement is a perfect temperature year round.

Hi there We are in the closing phase of the property which is a ranch type house about 1000sqft. Is it possible to get a quote on how much to remove all the old insulation, seal the air gaps and replace with new? regards
B Park Charles Blvd S. in Saint Peters
I have been struggling for several months at my home and have had multiple appointments with plumbers, hvac companies, and other specialists. However, we have not been able to come up with reasons/solutions for the problems I am having. The problems include several odor concerns (especially musty odors) and perhaps some negative air pressure issues. We are unsure if the ductwork and/or flue is involved. Ultimately, I am looking for someone who can work with me to investigate the cause(s) of the issues. Thank you.

I was interested in getting some pricing for the insulation of my attic. I am looking to finish the attic but want it insulated properly first.
Lynn Dr in Saint Peters
The attic does not have proper insulation. I want to remove the old which only was a (R19) and I would like to put an R47 with spray insulation. I also want to put some vents so the airflow can be efficient. (rafters and vents on the roof). I would like to know the cost of spray insulation for 1100 square feet.
