Old Farmhouse Fully Insulated in Marshallville, OH

Challenge

A homeowner in Marshallville, OH was having troubles living comfortably in his 1900's farmhouse. Seeing that the house was 100 years old, he knew that the walls and attic were either empty or close to it. He wanted a local company to come out and give expert advise to fix the problem for good. The customer found that Primary Home Improvements was his local insulation expert. He spoke to the Customer Care Representative and was quickly scheduled for a free in-home estimate.

Matt, the energy consultant, met with the homeowner and began to analyze the state of insulation in the home. Using a thermal imaging gun, he noticed the walls had absolutely no insulation in them. Additionally, there were huge gaps that were allowing drafts in from the outside. After climbing into the attic, Matt noticed very little insulation that was almost as old as the home. He measured about R-19 on the attic floor. R-19 is not high enough insulating power to protect this 890 square foot attic. Matt sat down with the customer and explained how RetroFoam in the wall and Tru-Soft in the attic would transform his home for the better. The customer was so excited to get this project done soon.

Solution

On the day of the install, the wall and attic crews both arrived to begin insulating this entire home. The wall crew began by taking off a piece of siding around the home in order to access the wall cavities in between the studs. Then, they drilled small holes so that they could pump RetroFoam injection foam inside the empty walls. RetroFoam is a tripolymer resin that fills existing walls with the best R-Value. There is no need to tear the walls down to the studs and the siding is put back up so you can't even tell the crew was there. Once hardened in the wall, RetroFoam will never settle and deters any drafts from entering the home.

While the wall crew was working, the attic crew was working on adding R-30 value to the space. To do this, they used Tru-Soft blown in cellulose and a high-powered machine to densely pack the insulation along the attic floor. Tru-Soft is mold and draft resistant.

Now having a fully insulated walls and attic, this customer can enjoy a comfortable and energy-effecient home!
