ABSTRACT OF THE DISCLOSURE CEILING LADDER A hinge for connecting two sections of a foldable ladder having a first section and a second section. The hinge is comprised of a first portion attached to the first section. The first portion has a first load bearing surface. The hinge is also comprised of a second portion having a second load bearing surface. The second portion is attached to the second section and is rotatably connected to the first portion such that when the first and second sections are aligned to form the ladder, the first load bearing surface contacts the second load bearing surface. A counterbalance assembly for a foldable ladder in a ceiling frame. The counterbalance assembly is comprised of a spring connected to the ceiling frame. The assembly is also comprised of a first arm having an offset, a second arm rotatably connected to the first arm, and a third arm rotatably connected to the second arm and to the ladder. The assembly is also comprised of a pivot plate fixedly connected to the ceiling frame and rotatably connected to the second arm such that when the ladder is fully extended, the offset of the first arm allows the rotatable connection of the first and second arms to be in alignment with the axis of the spring. A continuous hinge for a foldable ladder and a ceiling frame. The continuous hinge is comprised of a first leg connected to the ladder. Additionally, the continuous hinge is comprised of a second leg rotatably connected to the first leg and the external surface of the ceiling frame such that air is essentially eliminated from passing between the hinge and the ceiling frame. A foldable ladder having a plurality of sections which align during use to form a continuous ladder which are foldable upon themselves for storage in a ceiling frame. The foldable ladder is comprised of hinges for connecting the sections. Each hinge has a first and second load bearing surface which contacts each other when the ladder is extended. The ladder is also comprised of a counterbalance assembly, and a continuous hinge which connects the ladder to the ceiling frame and which essentially eliminates air from passing between the hinge and the ceiling frame.
