Mark writes from Cleveland, Ohio: "I have an older home (1920) that has minimal blown in insulation in the attic. I had a new roof installed with soffit vents, baffles, and a ridge vent. I would like to increase the insulation big time but my concern is since the attic has no floor, the insulation will be over the floor joists and one will not be able to see where the floor joists are in order to get in the attic. Though it would be seldom that access to the attic is needed, it is possible that one would need to get up there and I don't want to see a foot come crashing through the ceiling because someone doesn't know where the floor joists are. Do you have any suggestions?"

Answer: What you describe is pretty standard because most homes have the floor joists covered. The attic is not a place meant for foot traffic. When someone does need to access the space attic they need to use extreme caution when maneuvering around in the space.
