The system

The ZeroCut Building System, described plainly.

The ZeroCut e-SIP panel (enhanced - Structural Integrated Panel) is a structural panel system our founder invented and co-owns through Factory-Built Exchange (FBX), and which PreFab Innovations is licensed to build with. 

Plainly stated- the ZeroCut e-SIP panel is a highly efficient wall which is Class A fire-rated, takes 1/4 of the time to install and has high r-values.

Composition

  • Cold-formed steel framing

    The primary studs are a code-recognized cold-formed steel section, laid out on a standard 24" module. The section, gauge, and connections are specified by the engineer of record on each project.

  • Continuous insulation layer

    Insulation runs continuously across the exterior face of the framing, uninterrupted by fasteners through the primary studs. Thermal bridging through the wall assembly is limited to secondary attachments.

  • Factory-bonded air barrier

    The air barrier is bonded to the panel in the shop. The outer cladding half of the assembly is installed last, on site. That order of operations is what lets any licensed contractor build the system and keeps the assembly on the site-built side of the code, rather than a factory-built module.

  • Panelized delivery

    The wall arrives as panels sized to the plan. Framing on site becomes an install step. The mechanism for speed is fewer on-site operations, not a promised time figure.

  • Exterior cladding

    ZeroCut e-SIP panels use non-combustible fiber-cement cladding that meets the deemed-to-comply exterior covering requirement under IWUIC and California Chapter 7A.

Licensing

PreFab Innovations is licensed to build with the ZeroCut Building System.

The ZeroCut Building System was invented and is co-owned by our principal through Factory-Built Exchange (FBX). PreFab Innovations, Inc. licenses the system from FBX and builds with it on projects across California under CSLB license #1078820. Any licensed contractor can build with the ZeroCut Building System; PFI is one of them, and the most experienced.
