We just got our copies of the thermal images of our home from http://www.Sagewell.com, which they took last February. We got six photos, perhaps because we live on a corner. Warm spots on the house, like the windows, are red or yellow colored, indicating they are warmer, because more heat is escaping. Looks to me like our foundation should be insulated, as there is a short row of dancing yellow ribbons at ground level, and really bright yellow basement windows.
Just after looking at the thermal images I called Anderson Windows today to order a replacement balancer,and found myself asking if they sold storm window inserts – they said they do not. Just trying to get those reds and yellows a little darker.
It is useful information, and I recommend it to everyone. I believe that Sagewell photographed/imaged all houses accessible from the street in town, so even if you did not sign up in advance, contact them to see if you can get access to the images of your home.
