Specifications
- SF
- MF
Specification | Objective |
---|---|
Select sealants that: are compatible with their intended surfaces, allow for differential expansion and contraction between dissimilar materials, meet the requirements of the applicable fire safety code (e.g. thermal or ignition barriers), and for use inside the pressure boundary select low volatile organic compound (VOC) sealants that meet independent testing and verification protocols |
Select safe and effective sealants |

Specification | Objective |
---|---|
Apply a continuous seal at all seams, cracks, joints, edges, penetrations, and connections of the enclosure while applying sufficient pressure to push sealant into any gaps or cracks and contact any backing or infill material required Sealant exposed to the interior of the enclosure must meet the same fire rating as the enclosure |
Fully adhered, safe, and durable sealant |
