Russell, I think the intent of 8.16.4.1 is to not allow insulation on branchlines. As you've pointed out, critical parts of the sprinkler system (the sprinklers) will either be covered with insulation (major obstruction) or not insulated at all (defeating the whole purpose). I think your options are limited to a dry system, an antifreeze system, or dry sprinklers.
