Ściana oddzielenia przeciwpożarowego musi być wykonana z materiałów niepalnych, wzniesiona na własnym fundamencie opartym na konstrukcji nośnej o klasie odporności ogniowej nie niższej od odporności ogniowej ściany. Przegrodę należy wysunąć na co najmniej 0,3 m poza lico ściany zewnętrznej budynku lub na całej wysokości ściany zewnętrznej zastosować pionowy pas z materiału niepalnego o szerokości co najmniej 2 m i klasie odporności ogniowej EI 60.

fire separation
is a an assembly, such as a wall, that will act as a barrier against the spread of fire. A fire separation may or may not have a fire resistance rating. A

firewall
is a fire separation of
non-combustible
construction that separates or subdivides a building. A firewall must have a certain fire resistance rating (spelled out in the Building Code), and must maintain structural stability during a fire for a certain period of time.

During a home inspection we review components and elements that make up a fire separation firewallwall. In terms of the home, fire separation walls are built to prevent or delay the spread of fire and/or fumes between separate units. Fire separation walls are found between units in condos, townhouses and apartments, but are more commonly seen as the separation wall between an attached garage and the home. The purpose of this article is to provide general information about fire separation walls and why they are important in terms of safety.

FIRE WALL. A fire-resistance-rated wall having protected openings, which restricts the spread of fire and extends continuously from the foundation to or through the roof, with sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall.

Fire walls. The function of a fire wall is to form a required separation in order
to restrict the spread of fire through a building.
Every fire wall should extend from the foundation of a building to its roof.
Every fire wall is supplied with an opening. It is of great importance to note that
openings should be strictly restricted in size. Besides they must be closed with fire
doors or wired glass.
A fire separation wall, like a fire wall, forms a required separation to restrict the spread of fire through a building. But, unlike a fire wall, a fire separation wall does not extend from foundation to roof. Openings in fire separation walls are also restricted in size and must be closed with fire doors or wired glass.
Fire separation walls are used to divide a building between mixed occupancies
and for enclosure of stairways and exitway corridors.
