Rockwool Fire Barriers for External Wall Insulation (WDVS)

External Wall Insulation Systems (WDVS) offer superior thermal performance, but they require robust fire protection measures to comply with modern building codes. Rockwool fire barriers are engineered specifically to interrupt the vertical path of fire within the insulation layer, preventing it from spreading between floors.

Function and Safety

These barriers act as a non-combustible shield that maintains the integrity of the building envelope during a fire event. By compartmentalizing the insulation, they limit heat transfer and smoke migration, providing crucial time for evacuation and firefighting operations.

• Non-combustible mineral wool construction for reliable fire resistance.
• Effective containment of vertical fire spread in WDVS applications.
• Compatible with standard external wall insulation installation methods.
• Helps meet stringent fire safety regulations for multi-story buildings.

Installation Guidance

Proper installation is critical for the barrier to function as intended. It should be positioned at floor slabs or at regular vertical intervals as specified by local building codes and the system manufacturer's technical guidelines. Ensuring a continuous, gap-free installation is essential to maintain the fire compartmentalization.
