Cavity walls are an important feature in modern building construction as they provide a gap or space between two walls, which helps to prevent moisture from penetrating the inner wall and causing damage.
However, this cavity can also act as a chimney in the event of a fire, allowing flames and heat to spread quickly through the wall cavity and reach other areas of the building. In order to prevent the spread of fire and protect the building and its occupants, it is important to use fire-resistant insulation in the cavity walls.
Fire-resistant insulation in these walls can help to delay the spread of fire and provide extra time for occupants to evacuate safely. Additionally, fire-resistant insulation can minimize the damage caused by the fire and reduce the cost of repairs and rebuilding.
