Spray Foam Sealant and Energy Efficiency: Helping a Friend with Her New House
Posted on: August 30, 2011
Yes, I'm back. I couldn't leave my audience hanging. In my last article, I wrote about a friend
of mine who recently bought a house, had an energy audit and did some shopping at contractor-pro.com. Well, everything arrived (on time by the way) and we already installed the attic tent and stair covers. We had a few bumps along the way because we ordered a spray foam sealant, but not the tools to spread it. In the end, we got it done.
Honestly, installing the attic tent was a breeze! I just followed the instructions. I think she could have done it herself, but she claims to be an idiot when it comes to these things. I suppose that's true since she can't even put together something out of a box from the store. I, on the other hand, am pretty handy—even for a girl.
We also bought foam sealants since the energy audit revealed some gaps. The auditor found some of the gaps—the hard to detect ones, but he didn't find all of them. He told us how to find all of them. So that was our first task.
We started out by inspecting the house where different materials met: ceilings and floors, windows, and doorframes. We noticed the same large gaps fairly quickly. Since the furnace was already off, we also turned off the air conditioning, shut all the windows and doors, and turned on all the vents and fans to depressurize the house. We lit an incense stick and walked along the areas where there could be leaks. Sure enough, we found more leaks because the smoke from the incense was being sucked out.
As we got out the foam sealants to seal the leaks, we noticed that we didn't have what we needed. Simple things like having a Batt knife and spray sock seemed to slip my mind. But not worry, we were able to go to my local hardware store and get them. We were able to use the spray foam sealant and seal gaps in about one day with both of us working.
Easy as pie! Now my friend's home is ready for the winter since her attic has been sealed as well as the smaller gaps that once let out air. She'll probably even notice her utility bills in the summer decrease just a little.
