A firewall is an assembly of materials used to separate transformers, structures, or large buildings to prevent the spread of fire by constructing a wall which extends from the foundation through the roof with a prescribed fire resistance duration and independent structural stability.

What is a fire separation?

A fire separation is defined as “a construcfion assembly that acts as a barrier against the spread of fire.” … Fire separations such as floor assemblies and interior wall assemblies that have a required fire-resistance rating are therefore basic elements of fire compartmentation.

What makes a wall a fire wall?

A firewall is a fire-resistant structure 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 the collapse of the existing construction on either side of the wall to occur without allowing the collapse …
