L H Dottie Co HFB12 Fireblocking Spray Foam 12 Pack

Product Description

The L H DOTTIE CO HFB12 is a fireblocking spray foam sealant sold in a 12-pack configuration. Designed to seal penetrations and openings where building codes require a fire-resistant barrier, this foam expands to fill gaps around pipes, conduit, cables, and other trade penetrations through framing and assemblies. Fireblocking foam is a code-compliance tool used by electricians, plumbers, HVAC installers, and general contractors wherever the IBC or IRC requires penetrations to be sealed against flame and smoke passage. The multi-pack format supports commercial projects and stocking for repeat service calls.

Fireblocking foam sealant is applied at through-penetrations in wood-frame construction, including top and bottom plates, floor assemblies, and concealed draft openings. It is commonly used during rough-in inspections to satisfy fireblocking requirements before drywall or insulation is installed. The 12-pack quantity is suited for contractors running multiple trades on a job site or for supply houses stocking a consumable item used across plumbing, electrical, and HVAC rough-in work.

Compatibility

Designed as a general-purpose fireblocking foam sealant for use at pipe, conduit, and cable penetrations in wood-frame and similar construction assemblies where local building codes mandate fireblocking at rough-in openings.

Installation Notes

Fireblocking foam is typically applied by the installing trade prior to rough-in inspection. The substrate should be clean and free of loose debris before application. Follow local building code requirements, including IBC and IRC fireblocking provisions, to confirm approved products and application locations. Do not use standard expanding foam in place of a listed fireblocking product where a fire-resistance rating is required.
