Drywall firewall

Wall construction in dry construction that meets the requirements for fire walls under building regulations. In detail, this means that it

• is made of non-combustible building materials,
• is fire-resistant in terms of stability and room closure, and
• remains stable and enclosing the room even under additional mechanical impact

The classification of these requirements used to be done according to DIN 4102. Since 2002, however, new products have only been classified according to DIN EN 13501. As a non-load-bearing (drywall) wall, a fire wall has the fire resistance class Ei 90-M and all building materials the building material class A.

The exact construction method can be found in the building authority approval of the respective product. As a rule, the required increased mechanical resistance of a drywall fire wall is achieved by a full-surface sheet steel insert of approx. 0.5 mm thickness, which is attached on both sides of the wall below the uppermost planking layer.
