UNSPSC 30171616: Double-paned window

A type of window that has two parallel panes (slabs of glass) with a separation of typically about 1 cm; this space is permanently sealed and filled at the time of manufacture with dry air or other dry nonreactive gas. Such windows provide a marked improvement in thermal insulation (and usually in acoustic insulation as well) and are resistant to fogging and frosting caused by temperature differential.

UNSPSC 30171616 Double-paned window is a Commodity code capturing what state and local governments actually buy under this taxonomy: installation, repair, replacement, and security upgrades to window systems in municipal and institutional facilities. Recent opportunities show the code funds commercial glazing work ranging from routine maintenance and on-call glass replacement to specialized security applications—ballistic glass, shatterproof films, one-way privacy films, and tint installations—alongside full-building envelope assessments. Issuing bodies span state purchasing offices (Utah Division of Purchasing), county commissions and intermediate school districts (Lapeer County ISD, Pulaski County, Montgomery County), cities (Milpitas, Orlando, Fort Worth, Tucson, Berlin), and community colleges (Collin County Community College District). Solicitation types vary: RFIs for market intelligence and vendor qualification (Maryland Environmental Service, San Bernardino County); RFPs and RFQs for competitive awards; IFBs for routine services and material supply; and on-call requirements contracts with multiple awardees.

The geographic footprint spans at least twelve states with recent activity, including California, Colorado, Connecticut, Florida, Georgia, Michigan, Missouri, North Carolina, Pennsylvania, Texas, Utah, and Arizona. Representative recent opportunities include the City of Milpitas (IFB for shatterproof window film and installation under a Storefront Crime Prevention program, responses due September 1, 2026, with $100,000 in appropriated funding and California prevailing wage requirements); the State of Utah Division of Purchasing (RFP to establish a Ballistic Glass and Panels cooperative contract category under its Window Security Products Portfolio, responses due September 29, 2026, with multiple awards, UL 752-23 Level 7 certification mandates, and tiered scoring requiring 585 of 780 technical points to advance); Lapeer County Intermediate School District (sealed bids for one-way reflective and shatter-resistant window film installation, bids due July 28, 2026, with mandatory pre-bid July 15); and the Pulaski County Commission (RFP for Historic Courthouse window replacement with National Historic Preservation Act compliance, proposals due June 19, 2026). Prevailing wage requirements are common in the code's recent activity, particularly in California, Pennsylvania, and Texas. Set-asides and preferences appear sporadically—Section 3 reporting obligations in HUD-funded Tucson work, SBE eligibility in Fort Worth, community participation and apprenticeship goals in Pennsylvania projects, and HUBZone-equivalent local purchasing preferences in Utah and Milpitas.
