Fire stop pillows are specialized devices used in construction to prevent the spread of fire, smoke, and heat through openings in walls and floors. Made from fire-resistant materials, these pillows can be easily inserted into gaps around pipes, cables, and other penetrations, providing a temporary or permanent seal. When exposed to high temperatures, fire stop pillows expand and create a barrier that blocks flames and smoke. They are often used in commercial buildings, residential properties, and industrial facilities to enhance safety and comply with building codes. Their lightweight and flexible design make them easy to install and remove as needed.
