Cavity Fire Barriers.
It’s crucial to understand how cavity fire barriers work, and their role in improving building safety. Cavity barriers are designed to form cavity fire stops within the wall cavity, which can prevent the spread of fire through concealed spaces. These barriers are made from flexible materials, such as mineral wool or intumescent strips, which can expand when exposed to high temperatures or flames, creating a fire-resistant barrier.
The product can be installed in different configurations- horizontally or vertically, depending on the type of construction. Horizontal configurations are suitable between the edge of a concrete floor slab and the building exterior of masonry or curtain wall buildings. Vertical configurations, on the other hand, are used in curtain walls, where cavity barriers are installed at the edges.
Sills, jambs, and lintels should have fire stopping laid or secreted around them, and cavity barriers should be installed to close gaps or openings that could act as ventilation. This can help prevent the spread of fire and smoke throughout the building.
By providing a reliable barrier that can contain fire within its compartment, it can provide building occupants with significantly more time to evacuate and emergency services more time to control the situation. Building managers and contractors should invest in these essential safety measures to help ensure the safety of their tenants and employees.
