P #F9 OBAL SPEC TO INSTALL WE DO 1T ALL WOOD FRAME SPECIFICATIONS FOR WALK-1N COOLERS AND FREEZERS The following information is intended to aid specification writers, architects, and food service consultants with projects that require prefabricated modular cold storage vaults. GENERAL Walk-in coolers and freezers to be constructed with prefabricated panels formed to exact size as described below and manufactured by KPS Global - Fort Worth, Texas; Goodyear, AZ; Piney Flats, TN. INSULATION Insulation shall be 100% rigid urethane with an at temperature conductivity factor (K factor) not to exceed 0.128 Btu/hr. Urethane is to be poured in place with a density of 2.2 pounds per cubic foot. Overall coefficient of heat transfer (U factor) and the R value to be a follows: THICKNESS "U" FACTOR "R" VALUE 3-1/2" .036 25 4" .032 32 5" .025 40 This insulation shall be a listed urethane with a rating of no more than 25 for flame spread and 450 for smoke developed per ASTM E84. This urethane will also meet the requirements of ASTM D-1929. MODULAR PANEL CONSTRUCTION Alf panels to be constructed with die-formed interior and exterior metal pans securely fastened to a tongue-and-grooved perimeter frame of kiln dried spruce-pine-fir (SPF), #2 grade lumber. Perimeter frame to feature tongue-and-groove profile for positive alignment and sealing. Panel shall be filled with poured-in-place urethane which securely bonds to metal pans and perimeter frame creating a rigid structural panel. Standard panels shall be interchangeable for ease of assembly. Special panels (if required) shall be manufactured to the size required to obtain a specified vault size. PANEL FASTNERS Cam-lock fasteners shall provide a tight and positive seal. Fasteners reduce on-the-job installation time to a minimum. Fastener material shall be steel housing, hook and pin with high-pressure die-cast zinc cam. Hardened steel hexagonal wrench is provided to tighten panel fasteners. The hook of the fastener shall engage over the pin when rotating the wrench and with cam-action, draw the panels tightly together, Polyethylene snap-in caps cover the wrench holes. Lock spacing shall not exceed 48" on center. SECTION 1/PAGE 1 Due to continuous improvement programs, specifications are subject to change without notice.
