LSF is a fire-resistant ladder which allows an easy and safe access to the attic, and at the same time serving as a fire block during a fire inside of the building. A contemporary system of folding of the ladder enables the ladder to be folded to smaller lengths and therefore allows smaller sizes of loft hatch to be attained. The inner part of the frame is equipped with a gasket, which under the influence of high temperature expands and prevents the smoke from entering the higher floors.
