About this file
This is a specification document for building insulation work prepared by Fontana Unified School District (FUSD), a K-12 public school district serving approximately 32,000 students across 45 school sites in San Bernardino County, California. The specification details requirements for thermal and acoustical batt insulation installation in portable buildings and other structures, including unfaced mineral fiber batts for enclosed areas, faced mineral fiber batts with vapor barriers for exposed or high-humidity areas, and fiberglass batts for acoustic applications. The specification requires all insulation materials to meet minimum standards including flame spread ratings not exceeding 25 and smoke density not exceeding 50 per ASTM E 84, compliance with California Building Code Chapter 7 and California Energy Commission 120.7, and a minimum 30 percent recycled content. Acceptable manufacturers include Owens Corning, Johns Manville, and CertainTeed Corporation. Installation requirements are detailed for various applications including exterior walls, roof decks, metal framing, ceiling joists, and horizontal or sloped installations, with specific provisions for vapor barrier orientation, compression limits, wire support, and protection of penetrations.
The District issued Bid No. 25/26-0045 for Portable Buildings - Maintenance & Repairs with sealed bids due no later than 2:00 pm on Tuesday, May 26, 2026, through the procurement portal at https://procurement.opengov.com/portal/fusd. The contract duration is four additional years, not to exceed five years total, with an estimated annual cost of up to $1,500,000 for portable building maintenance and repairs. The District notes that this estimate is provided for informational purposes only and does not constitute a guarantee, obligation, or commitment to spend this amount. All insulation materials must be listed as low-emitting on the CHPS website or independently tested to meet CHPS Section 01 81 13 standards, and materials must be delivered in safe, dry storage with labels intact and protected from damage, humidity, moisture, and sunlight during handling.

b. Batts Under Metal Roof Decks where underside of insulation will be exposed install foil-faced flanged-type insulation batts and staple flanges together at maximum 4" centers and seal joints at abutting vertical surfaces with a pressure-sensitive plastic tape. Where underside of insulation will be inaccessible, install secure with spindle anchors. Provide 18 gage galvanized string wires under batts wherever necessary to prevent sagging.

Do not install insulation over recessed lighting fixtures, speakers, or other heat producing elements in ceilings. At junction boxes, access panels, and other items requiring access from above or below ceiling, cut insulation on each side to fit item and install loosely on top. Fit insulation snugly around ducts, conduits, pipes, and other items projecting through ceiling construction.
