It is obvious that services passing through unsealed openings in fire resisting elements of structure will also allow flames, smoke and hot gases to pass through creating an unnecessary hazard. We are able to supply and install a selection of products designed to seal these gaps, providing an effective fire resistance of up to 4 hours. The type of product used would depend upon the special needs on site.

Mortar systems are used where mechanical strength is required such as service penetrations in floors which may be required to accept foot traffic or around fire dampers which require rigid support. They are also ideal for sealing odd shaped or poorly accessible spaces in horizontal penetrations because the mortar will flow around the services completely filling the void. Mortars are available in densities typically between 800kg/m3 to 2000kg/m3.
 

Mineral wool slabs for fire stopping are supplied in various forms; often referred to as batts, slabs or panels. Manufactured from a range of high melting point mineral wool of densities ranging from 100kg/m3 to 200kg/m3. They can be used in a wide variety of fire stopping applications to seal penetrations through walls and floors and, being softer than mortar, allow the easy installation of further services. However the seal must be properly reinstated after further services have been installed.
