All of this talk of construction methods comes from me as I am remodeling my second bedroom in my McCormick Ranch town home. This room is the west room, upstairs above the garage; so no chance of planting a tree and getting a spot of shade on that wall.
The room has been HOT in the summer and COLD in the winter. It boasts a single pane glass window and single pane glass sliding door, and an assumption on our part that the insulation was missing in the walls.
Our plan, remove the wall board, replace the windows with Low-E, and replace the sliding door with a dual pane French door, and insulate the walls to the max!
Here goes our transformation!
