What Partition Specialties, Inc does

Partition Specialties, Inc. (PSI) is a privately held California corporation founded in 1958 that distributes and installs architectural space management products — operable partitions, vertically folding walls, demountable glass wall systems, and raised access floors — for commercial interior projects across California and northern Nevada. The company serves as a certified distributor for multiple manufacturers including Modernfold, Skyfold (relationship since 1993), Tate Access Floors (since 1992), Euro Wall Systems (since 2022), Klein, LaCantina Doors, Moodwall, and Interlam, and employs union installers alongside a direct regional field-sales force.

PSI generates revenue through one-time product sales bundled with professional installation services, and through a recurring after-sales service and maintenance stream that covers preventative maintenance, panel recovery and replacement, retrofit, emergency service, and warranty work on installed operable walls. Pricing is quote-based and project-specific, with sales cycles driven by architects, designers, general contractors, and end-users specifying products during commercial construction or renovation. The company operates from five regional offices (Novato HQ, Hayward, West Sacramento, Santa Fe Springs, and Oceanside) and maintains documented customer relationships across enterprise technology (Salesforce, Twitter HQ), legal (Katten Muchin Rosenman, Resource Law), education (multiple K-12 and charter schools), government (Cal EMA, SACOG, San Jose Convention Center), healthcare (UCSF), and hospitality (Sequoia Groves Winery, Fairytale Town).

Since 1998, ownership has been held by Shawn Still, Ryan Iwasa, and Randy Squires, who acquired the company from retiring co-founder Ed Still. PSI has pursued growth primarily through new distribution partnerships (most recently Euro Wall Systems in 2022) rather than acquisitions or external capital, and operates with no disclosed parent company, public listing, or venture funding.

Direct peers

• Kwik-Wall: Kwik-Wall manufactures and installs operable partitions, accordion folding partitions, and moveable glass walls. Directly comparable in product category (operable walls) and customer use cases (commercial interiors, education, hospitality).
• DIRTT Environmental Solutions: DIRTT manufactures modular demountable wall systems for commercial interiors, addressing the same flexible-space and reconfigurability problem that PSI addresses with Skyfold, Modernfold, and Moodwall. Competes for architect-specified interior fit-out budgets.
• Hufcor: Hufcor is one of the largest US manufacturers and direct installers of operable and accordion partitions. Like PSI, it sells and installs moveable wall systems for commercial interiors; PSI is a distributor of competitor products in California.

Broad incumbents

• Skyfold: Skyfold manufactures the vertically folding operable walls (STC 48–60) that PSI distributes and installs in California. As a manufacturer, it competes with PSI's product line outside of California and shares the same end customer base (5,000+ walls installed worldwide).
• Haworth: Haworth is a global manufacturer of office furniture, architectural interiors, and movable wall systems. Its portfolio includes products directly comparable to Modernfold and Skyfold, and it competes for the same enterprise and education specification budgets.
• Steelcase: Steelcase is a leading global office furniture and space solutions provider. While it does not specialize in operable partitions, its architectural solutions and demountable wall programs overlap with PSI's commercial interior value proposition for enterprise customers.
• Allsteel: Allsteel, a brand within HNI Corporation, offers architectural wall systems and office furniture, including demountable and movable wall products. It competes with PSI for corporate interior and tenant improvement specification work.
• Tate Access Floors: Tate (a Kingspan brand) manufactures the access floor systems that PSI distributes and installs. As a manufacturer with its own certified installer network, it competes with PSI's installation business for commercial infrastructure and data center projects.
• Modernfold: Modernfold is one of PSI's core manufacturing partners but also operates its own nationwide distributor/installer network. It is a broad incumbent in operable partitions (including Acousti-Seal up to STC 56) that overlaps directly with PSI's product offering in other regions.
• Euro-Wall Systems: Euro-Wall is one of PSI's manufacturing partners (since 2022) producing American-made folding, sliding, stacking, and pivot glass door systems. As a manufacturer it serves similar commercial/institutional projects as PSI but through its own dealer network.
