The DDP SPECIALTY ELECTRONIC MATERIALS 99112831 is a 12 oz fire block insulating foam sealant designed to help impede the spread of fire and smoke through service penetrations in walls, floors, and ceilings. Dispensed through a smart dispenser, the sealant expands to fill, seal, and insulate gaps up to 0.75 inches, forming an airtight, water-resistant bond. The cured foam is bright orange, allowing for straightforward visual confirmation of coverage during inspection. Licensed contractors, plumbers, electricians, and HVAC technicians use this product when sealing around pipes, cables, and ducts that pass through fire-rated assemblies.
This sealant is suited for both residential and commercial applications wherever building codes require fire stopping at service penetrations. Common install scenarios include sealing conduit and pipe sleeves through fire-rated walls or floor-ceiling assemblies, and around duct penetrations in mechanical chases. It is recognized as an alternative fire blocking material under applicable standards, making it a code-compliant choice for penetration sealing during rough-in and finish work.
Designed for use at service penetrations through fire-rated wall, floor, and ceiling assemblies involving pipes, cables, and ducts in residential and commercial construction.
This product is typically applied by licensed plumbers, electricians, or HVAC technicians during rough-in or final inspection stages. Before applying, verify the substrate is clean and free of dust or debris, and follow local building and fire codes, including IBC and IFC requirements for fire stopping at penetrations. Do not apply over open flame or in areas with active ignition sources, as the propellant is flammable before cure. Allow full cure time before covering or enclosing the sealed area.
