FIRE RESISTANT ATTIC STAIRS
Attic stairs are constructed out of a box, a ladder, a box closing hatch, so that the ladder is suspended from attic stairs box using hinges and the closing hatch is suspended from the ladder. The closing hatch features a stratified structure, including an inner layer located between two rigid outer strata, where the inner layer is entirely filled with a fire resistant material.
