It took all I had not to turn and inch my way down the ladder. The attic was approaching 120 degrees. My covering consisted of a Tyvek suit tied at the ankles with foot coverings, gloves, mask and a headlamp. It was a small attic with a low ceiling. Heather and Kevin were blowing insulation. They had already applied a line of foam sealing. I was determined to stay in the stifling heat and carefully walked on the planks so as not to go through the ceiling. It was an experience of 15 minutes that will be long remembered. They were saving the world one house at a time.
