I live in a Victorian carriage house built in 1898 with a sizable loft which serves as my bedroom. The room roasts in the day and freezes at night. The "ceiling" in the loft is actually the roof line. It comes down 12 feet from the top of the house at a 45° slant to the 20 inch knee wall. You can imagine the challenges of retro-filling such a space. At the top of the room (where the walls meet in pyramid shape), there are removable ceiling panels giving access between the joists (or are they studs) down to the knee wall. A friend and I used your slow-rise spray foam with an 8 foot hose extension to get to the base of the opening. This access point allowed us to insulate most of the loft, although we needed to drill holes in the walls to fill in the corner spaces.
I can't believe the difference in temperature--both cooler in the day and warmer at night (I took an extra quilt off the bed). I had enough spray foam left over from the loft to insulate the north east wall of my living room. My heating bill is about half of what it used to be. By the way, I am a 59 year old woman who teaches college during the day and my assistant is a retired computer programmer. We followed directions and had no mishaps. It was a project, but one we could manage with our minimal handyman skills. My only regret is that I didn't use spray foam insulation earlier (I've lived in this house for 4 years). Thank you for this great product!
