Fire-Resistant Loft Ladder LSF

LSFThe LSF Fire-Resistant Loft Ladder acts as a blaze block in case of fire inside the building preventing the smoke from entering the fire-free storey, thus providing additional precious time for the fire services to arrive in the event of emergency. The loft ladder fire-resistance is EI₂= 60 minutes (classification according to EN 13501-2).The overall floor-ceiling ladder height can be increased to a maximum 320cm by adding one LSS segment.The loft ladder hatch is equipped with an expanding seal, which under the influence of high temperature increases its volume and prevents the smoke and fire from spreading to the fire free storey.
