Fireclamp A Fire Resistant and Acoustic Sealant
Prevents the passage of fire, smoke and sound
Fireclamp A is an easy-to-apply, highly flexible polymer emulsion sealant designed to provide fire protection wherever internal low movement and/or acoustic joints are required.
When exposed to high temperature it swells to form a durable char that restricts the passage of smoke and fire for up to 4 hours.
Fireclamp A is a halogen-free, polymer emulsion based sealant that swells when subjected to temperatures in excess of 125°C to form a durable char that restricts the passage of smoke and fire. It is easy to apply and is designed for internal use wherever low movement fire resistant and/or acoustic joints are required.
In addition, it has also been extensively fire tested to provide fire seals around a wide range of pipe and cable service penetrations through fire compartmenting floors and walls including 100mm thick flexible (plasterboard) partitions.
Fireclamp A has been tested to the latest European requirements for applications in walls and floors. Testing to other national standards is also available.
