How We Saved a Homeowner 50% on Heating Costs

We recently documented an insulation job from start to finish and want to share the process, reasoning, and results with all of you.

We started by removing all the old insulation in the attic. 

Why remove old insulation?

In this case, the owner was uncomfortable with the old insulation due to its age and all the dirt it had collected over the years. Vacuuming out all the old insulation also allows us to ensure proper insulation techniques throughout the home, instead of just putting new insulation on top of old insulation, which may or may not have been properly installed.

In this case, it was especially beneficial for us to remove the old insulation, as we discovered some sketchy wiring hiding beneath the insulation. After we got a clear view of several wiring issues, an electrician was brought in get everything up to code. 



After the wiring issues had been taken care of, we started by adding baffles, which insures proper air flow for the attic ventilation system.  We also stuffed fiberglass batt insulation (pink) under the baffle to keep the blown in cellulose insulation from blocking air flow. This is critical because we dense pack the insulation right here. The ceiling and wall intersection is the most critical point of the ceiling plane because this area is fighting heat loss through conduction through both the ceiling and wall. It has an energy loss battle form 2 sides.  


We then worked to seal penetrations throughout the entire ceiling plane with spray foam insulation. Much like many of the houses we work in, this home was riddled with holes that were not properly insulated previously. We paid special attention to the area above the kitchen cabinet, which is notorious for being overlooked and under insulated. We used closed cell 2 part polyurethane to seal this up properly.

We also made sure the flu/chimney pipe was blocked so that the insulation would not touch the heat-producing pipe.

The attic hatch is also an often-overlooked area. We made sure to weather-strip the door to make it air-tight and insulated the lid to match the rest of the ceiling plane. We also installed a barrier to block insulation from falling on the homeowners head when they open the lid to access the attic.


We always use R-sticks to ensure that our installers are insulating to the proper level. We install cellulose at 1.45 lbs per cubic feet and we follow the guide provided by the manufacturer, which indicates how many bags to use, so you will always know that we didn't use any tricks to fluff up insulation to make it look like we used less than needed to truly be at R-49.



 For this house we installed 90 bags of cellulose, which is an entire truckload.

 The airtight insulation we installed in this homeowner’s attic will last for 25 years and save her 50% on her heating costs, all while making her home less drafty and more comfortable. These are the kind of jobs we love doing because we can be confident that the homeowner will immediately begin seeing a return on investment on their energy bills.
