Very Expensive Icicles
After thousands of dollars spent on insulation, I still have ICICLES! It is so disheartening. A guy tries to do his best. I researched and interviewed until I was blue... failure! I could've bought a lot of heat tape for the amount of money I've got into insulation in this place (or taken a nice cruise to a warm "ice-free" place).
One of the culprits is that, in place, the Icynene spray foam appears to have shrunk some and pulled away from the roofing & framing - which is not good. The other issue is that they scrape the icynene away from the bottom of the rafters so that drywall can be attached. In my opinion, this wicks the heat up to the roof surface and melts the snow. I just bought a few hundred more dollars of polystyrene foam board and will attach it in these areas to try to insulate these rafter faces. Will see what happens.
I also had they icenyne added to an exterior wall of an upstairs bathroom in attempt to keep it a little toastier.
I didn't insulate any walls in the house in that most every wall is covered in huge windows -- OVER 80 OF THEM -- in this place. I figured what little wall space there was would not benefit from insulation in that most of the house is covered in glass.
