James writes from Ansonia, Connecticut: "My home was built in 1925. An old Victorian Colonial. I have an attic that is very high, 13'6" from the floor to the peak. I have added a second story in the attic @ 89" using 2x6 collar ties attached to the roof rafters (also 2x6 full lumber for the existing roof rafters).I have put OSB as the flooring in the new storage area. I am getting ready to install R-19 faced PINK utilizing roofmate baffles. My question is should I run the insulation all the way to the peak or should I stop and do under the OSB on the new collar ties(New Storage Rafters)and leave the storage area unisulated above, to the peak."

Answer: The only reason for insulating the rafters to the peak is if you are going to finish that part of the attic space or need warm storage. If neither is the case, insulating the floor over the newly finished area should be sufficient.
