When I crashed last night at about 11:30, it was 70 degrees in the house with the prospect of a night in the low 40s. I thought I'd see how my new insulation job from Better Building Works does, so I didn't turn on the heat.
When I got up at a little before 7 this morning, it was 41 degrees outside and 69 inside. That's a loss of one degree overnight with an outside temp that likely went below 40 overnight. Barry Martin, who installed the insulation, said I would save some money this winter on heat. Seems to know what he's talking about.
