FLOOR REQUIREMENTS (continued)

Sound insulation In modern high-rise buildings, where many people have to live or work most of their time acoustic insulation is a very important factor. The floor must provide the necessary insulation against airborne noise and footstep sound. Speaking about this acoustic function, the floor comprises one or more layers:

The single-layer floor comprises only the structural floor.

The two-layer floor comprises the structural floor and a surfacing separated from it by a resilient insulating material classified as floating floor. A two-layer floor may consist of the structural floor with a suspended ceiling fitted below.

The three layer floor is a combination of the two latter forms of construction that is a floating floor with a suspended ceiling.

Fire protection The fire resistance of a floor required can be achieved in various ways:

• for the floor slab itself: choice of a fire-resistant form of construction or a protective coating or finish;

• for the steel beams: sprayed protection or cladding;

• as an alternative, the floor structure as a whole may be encased.

Heat insulation If a floor separates a heated storey from one that is not heated, it should comprise a heat-insulating layer, which is not needed if the storeys above and below the floor are both heated. Terraces should be heat-insulated on the same principles as for flat roofs.

Notes:

airborne noise воздушный шум

floating floor плавающий пол

footstep sound звук шагов

heat v. нагревать
