Sika’s flexible solution for fire rated joints

Latest News Mon, Jul 26, 2021 1:55 PM


Not only are building joints potential weak spots for air and water leakages, but they can also fuel the spread of heat, smoke and flames. For effective passive fire protection, Sikasil® 670 Fire Rated Silicone Joint Sealant from building chemicals manufacturer Sika can help to contain and control the propagation of fire by restoring the fire resistance for both internal and external joints.

Sika’s Sikasil® 670 Fire Rated Silicone Joint Sealant can be used with standard polyethylene foam backing rods to achieve the required level of passive fire protection, and is fire rated to offer up to 4 hours of fire resistance according to EN 1366-4.

Ideally suited for both wall and floor joints, and particularly movement and connection joints within fire compartments such as stairwells and corridors, Sika’s Sikasil® 670 Fire Rated Silicone Joint Sealant has been specifically developed to offer exceptional flexibility . It can also be used on various porous and non-porous substrates, both inside and out. Easy to work with and with excellent adhesion, the sealant is moisture-curing and is highly resistant to weathering.

Sikasil® 670 Fire Rated Silicone Joint Sealant is part of Sika’s extensive range of passive fire protection solutions, developed to help contain and control the spread of fire and to restore the fire resistance of linear joints, cavity barriers and penetration seals. By helping to contain and control fire, Sika’s passive fire protection range can help extend the time for occupants to be safely evacuated when used as part of a comprehensive fire safety strategy.

Further advice, product guidance and full specification support are also available, with Sika’s team of experienced technical team able to produce detailed evaluations for more complicated applications based on key criteria such as the substrate, type of joint and anticipated level of movement.
