NIGP 91453: Insulation

NIGP 91453 Insulation, an Item code, covers spray foam installation, attic insulation removal and replacement, and mechanical equipment insulation services that state and local governments procure for facility maintenance, energy efficiency upgrades, and equipment preservation. Recent solicitations show government buyers using this code for both specialized insulation work tied to building systems and standalone insulation projects at educational institutions, utility facilities, and state-operated buildings.

State and local issuing bodies soliciting under 91453 include community colleges and technical colleges (Skagit Valley College, Bellingham Technical College, Tacoma Community College, Walla Walla Community College), state departments (Washington Department of Enterprise Services, California Department of Veterans Affairs), regional water authorities (Tampa Bay Water), counties (Kane County, Illinois), and specialized state agencies (Washington Department of Corrections, Department of Social and Health Services). Washington State community colleges appear frequently as repeat buyers. Recent opportunities span Washington State (dominant activity), California, Illinois, Florida, and Georgia, with Washington showing the heaviest concentration of solicitations posted in the past ninety days. Representative recent opportunities include Kane County, Illinois requesting spray foam insulation installation and permitting at Mill Creek Greenway Forest Preserve (RFQ posted June 18, 2026, due July 8, 2026); Tampa Bay Water requesting attic insulation removal, sanitation, and replacement at the Cypress Creek Pump Station building in Hillsborough County, Florida (RFQ posted June 10, 2026, due July 1, 2026); and Washington State Department of Enterprise Services soliciting on behalf of Skagit Valley College for HVAC equipment replacement with associated mechanical insulation work in Nelson Hall (IFB posted May 21, 2026, due June 18, 2026). Procurement activity under this code remains modest compared to broader construction and facility maintenance categories; however, the recent pipeline reflects steady demand for specialized insulation services tied to HVAC system upgrades, energy performance improvements, and facility condition assessments.
