Fire-rated sealants

How can we limit the spread of fire when it comes to building design? Including passive fire-protection in the building design helps contain fire and smoke, allowing more time for building occupants to escape. This is why building materials we select are so vital: the materials’ behavior in resisting fire is a key factor in determining how much time will be available to exit a building. Dow High Performance Building offers a range of DOWSIL™ brand solutions for vertical and horizontal applications as well as cable penetrations, fenestrations and building element connections, including DOWSIL™ FIRESTOP 700 Silicone Sealant.

A distinct advantage

Sealants can play a key role in the system design and help limit the spread of fire and smoke. Silicone technologies are non-flame propagating, do not produce flaming droplets and have a limited non-toxic smoke development. These material properties can be especially beneficial in fire-rated systems and designs and are found in DOWSIL™ FIRESTOP 700 Silicone Sealant, which is suitable for horizontal and vertical linear joints and penetration seals in walls. This product has a fire rating of up to four hours and benefits from the renowned characteristics of silicone sealants  such as movement capability, adhesion profile, UV and temperature stability and durability.
