Promaseal® Fire Pillows can provide permanent protection from the spread of fire, but they are particularly useful when only temporary protection is required. Promaseal® Fire Pillows have been successfully fire tested up to 120 minutes.
Promaseal® Pillows are manufactured from treated cloth filled with a high density, granulated fire seal mineral wool. When exposed to fire, the pillows remain in place and char, thus forming a fire barrier of a solid mass of insulating material.
Promaseal® Pillows are used in special occasions where other fire barrier solutions cannot be used. Between 100 and 130 numbers are usually required per m² of an open area; however, the pillows can be easily placed in many openings where it would be difficult to apply other products or wet systems.
In the case of smaller penetrations, it is often more economical to use the pillows, especially if labour costs are a concern, because the required fire performance can be achieved with the application of just a few pilllows
