What PABCO Gypsum does

PABCO Gypsum is a North American manufacturer of gypsum wallboard and specialty acoustic drywall panels, operating as a division of PABCO Building Products, LLC (itself part of Pacific Coast Building Products, Inc.). Founded in 1976 and headquartered in Rancho Cordova, California, the company runs a manufacturing plant in Las Vegas and a QuietRock customer contact center in Newark, serving both U.S. and Canadian markets. Its portfolio spans regular interior, fire-resistant (Type X), mold/moisture-resistant, ceiling, abuse/impact-resistant, exterior/exposure-resistant, shaftliner, and interior/exterior glass mat gypsum panels, plus the QuietRock sub-brand of sound-reducing drywall.

The company's core differentiator is QuietRock, built on a patented constrained-layer damping architecture using a proprietary viscoelastic polymer adhesive between gypsum layers to achieve high STC ratings in a single panel. EZ-SNAP technology further enables score-and-snap cutting with standard drywall tools by eliminating interior paper or metal layers. The acoustic system is rounded out with accessories (QuietGlue Pro, QuietPutty, QuietSeal Pro) and supported by more than 220 fire- and sound-tested wall assemblies documented in the 2025 Sound Design Guide, a BIM library (BIMSmith Forge, Revit), MasterSpec integration, and a Sound Assembly Tool selector for architects. Products carry ASTM C1396, ASTM E84, UL, CAN/ULC-S102-10, GA-600, EPD, and VOC certifications.

PABCO Gypsum sells exclusively through authorized building-material distributors (ABC Supply, FBM, Frontier Drywall Supply, GTS Interior Supply, L&W Supply, Foundation Building Materials, and others) across the U.S. and Canada, with no direct-to-customer channel. Quote-based pricing is set at the dealer level. End customers span residential and commercial construction, architects/specifiers, contractors, and developers, with documented projects in healthcare (California Pacific Medical Center), airports (Calgary International), hospitality (Mayton Inn, Candlewood Suites), and multi-family residential (Orion at Lumino Park). The company is privately held within a multi-division building products conglomerate, with no public financials, funding rounds, or investor disclosures available.

Direct peers

• USG Corporation (Knauf USG): USG is the largest North American manufacturer of gypsum wallboard and specialty acoustic panels (e.g., Sheetrock, USG Levelrock). It is the most direct competitor to PABCO across regular, fire-rated, and acoustic product lines, and was acquired by Knauf in 2019 to form Knauf USG.
• National Gypsum Company: National Gypsum is one of the four largest U.S. gypsum wallboard producers, offering Gold Bond, XP, and eXP sheathing lines. It competes head-to-head with PABCO in regular interior, fire-resistant, and mold/moisture-resistant panels, and also distributes through dealer networks.
• American Gypsum: American Gypsum is a U.S. wallboard manufacturer producing regular, Type X, mold-resistant and glass-mat panels sold through building material dealers. As a similarly sized, privately held domestic producer, it is a close comparable to PABCO in product mix and channel strategy.
• Continental Building Products (operated by Knauf): Continental Building Products manufactured a full line of regular, Type X, mold-resistant, and glass-mat wallboard before being acquired by Knauf. Its product set and channel overlap with PABCO made it a direct North American peer, and Knauf now leverages those plants against the broader competitive set.

Broad incumbents

• CertainTeed (Saint-Gobain): CertainTeed, the building products arm of Saint-Gobain, manufactures gypsum board (GlasRoc, SilentFX) as part of a much broader portfolio that includes insulation, roofing, and ceilings. Its SilentFX line competes directly with QuietRock in the acoustic panel segment.
• Georgia-Pacific Building Products: Georgia-Pacific is a top-three North American gypsum board producer (ToughRock, Dens) and a major force in adjacent panels, sheathing and mat-faced boards. It competes with PABCO across commodity and specialty lines through a deep dealer and home-center channel.
• Knauf (Knauf Gips): Knauf is a global gypsum and building materials giant, now the parent of USG and Continental. It competes broadly with PABCO worldwide on wallboard, plasters, and acoustic systems and represents the largest non-public incumbent in the space.
• Owens Corning: Owens Corning supplies acoustic batts, sound insulation, and complete wall systems that overlap with QuietRock in the acoustic assembly value chain. While not a wallboard manufacturer, it competes for the same spec-driven acoustic performance budget on commercial and residential projects.

Others

• ClarkDietrich Building Systems: ClarkDietrich is a leading North American manufacturer of cold-formed steel framing and clip systems used behind gypsum wallboard. While not a panel maker, its framing systems are frequently paired with—or specified against—acoustic gypsum panels like QuietRock in sound-rated assemblies.
• Atlas Roofing Corporation: Atlas Roofing produces exterior sheathing, glass-mat panels, and polyiso insulation used in commercial wall assemblies. Its ACFoam and exterior sheathing lines overlap with PABCO's glass-mat and exterior exposure-resistant panels for commercial envelope applications.
