Firestopping
R&L Ohana installs UL-classified firestop systems on commercial construction throughout Hawaii. Every penetration goes in to a specific listed system with the correct F and T ratings for the assembly, and every one of them is documented.
What the Scope Covers
Through-penetration firestopping for mechanical, plumbing, electrical and communications penetrations, plus head-of-wall, bottom-of-wall and expansion joint systems. Materials include sealants, intumescent wrap strips and collars, mortar, pillows, composite sheet, cast-in devices and membrane penetration protection. We self-perform section 07 84 00.
Documentation
On a project with thousands of penetrations, the documentation is as much of the deliverable as the material. Every penetration is installed to a named UL system number and recorded, so that when the fire inspector walks the building you are not reverse-engineering what went into a sleeve eight months ago.
We hand over an organized firestop submittal and closeout package matched to the installed work. Inspectors pass buildings faster when the paperwork matches the wall.
How We Run the Work
Coordination
Firestopping is a trailing trade that depends on every other trade finishing their penetrations. We walk the building with the general contractor, identify what is ready and what is still open, and come back for the stragglers rather than calling it done with sleeves unaddressed.
Correct system selection
The right system depends on the assembly, the rating, the penetrant and the annular space — not on what is on the truck. Where field conditions do not match an available listing, we engineer judgment it through the manufacturer rather than installing something close and hoping.
