Specifications
GENERAL
Enviro Buildings shall be constructed of prefab, precision-formed, modular panels designed for accurate, rapid field assembly. Enviro Buildings shall be test assembled at the factory.
DRAWINGS AND INSTRUCTIONS
Each Enviro Buildings shall have a set of installation instructions and lay-out drawing. All panels shall have panel identification corresponding with the lay-out drawing to facilitate rapid and accurate field erection.
PANEL CONSTRUCTION
Each panel shall consist of inner and outer metal skins, a 4″ insulation core, and be equipped with cam-action locking devices. The locking devices shall be operable from inside the walk-in and a hex-shaped wrench shall be supplied. Press-fit plug buttons shall be provided to seal wrench holes after assembly is complete.
All panels shall be connected to one another by placing the tongue of the insulation core of one panel into the groove of the core insulation of the adjacent panel. The resultant tongue and groove joint shall be sealed at both sides by double barreled gaskets. In order to avoid future swelling and mold formation, no wood shall be permitted in the manufacture of the tongue and groove panel profile.
PARTITIONS
When specified, Enviro Buildings shall be divided into compartments by the use of panels that are constructed in accordance with the specifications for all panels.
FLOOR
Exposed Prefabricated Floor: Prefabricated Enviro Buildings floor panels must have R-28 rating or greater; allowable stationary load of 600 pounds per sq. ft. when placed on a continuous concrete slab, reinforced floor panels for larger loads are available; verify that building is transit level prior to installing Enviro Buildings; notify Owner and Architect if sub-floor ventilation or heating is required for Enviro Buildings; Dealer or Consultant to verify that sub-floor installation conditions are acceptable prior to installing floor and box.
FLOOR SCREEDS
Floor screeds shall be provided for all floorless walk-ins. The screeds shall be vinyl, and have cove both inside and out.
PANEL FINISH
Metal finish of the panels shall be as follows. (Specify finish desired, combinations may be used) Interior or exterior walls, ceilings, and exterior floors
• 26 gauge galvalume
• 26 gauge painted
• 26 stucco stainless steel
INSULATION
Based on customer preference panel insulation may be Extruded Polystyrene, manufactured in an HFC and CFC free process, made from 60% recycled materials and 100% recyclable. Door insulation may be Polyurethane. Or panel insulation may be Expanded Polystyrene, manufactured with a HFC and CFC free process.
Extruded Polystyrene
All wall and ceiling insulation shall be 4” thick, high quality, rigid extruded polystyrene, 1.6 lb density. K factor of not more than .139 and an R-factor of not less than 7.2 per inch, initial fresh R-32 minimum total wall R factor. Vapor transmission shall be less than 1 perm and foam core material must meet UL 5 flame spread rating with average smoke rating less than 165. (UL 723)
Expanded Polystyrene
All wall and ceiling insulation shall be 4” thick, high quality, rigid extruded polystyrene, 1.6 lb density. K factor of not more than .139 and an R-factor of not less than 7.2 per inch, initial fresh R-18 minimum total wall R factor. Vapor transmission shall be less than 1 perm and foam core material must meet UL 5 flame spread rating with average smoke rating less than 165. (UL 723)
PASSAGE DOORS
(Standard door is 34″x76″; alternate sizes are available upon request).
DOORS
Door shall be flush mounted, positioned and hinged per drawings. Doors shall be provided with suitable sweep and magnetic gaskets. Door shall be provided with door closer, one pre-wired vapor proof light fixture, light switch with pilot light, dial thermometer, manual internal lock override, chrome plated cam lift hinges, and chrome plated door latches with strike. Doors on outdoor Enviro Buildings shall have weather protected light switch and door drip cap.
RAIN ROOF
(For use on Enviro Buildings installed outside) (Specify whether Enviro Buildings is free standing or which wall is butted) A single-ply membrane roof shall be supplied to provide a water resistant covering of the ceiling panels. Membrane material shall be provided in one complete roll designed for the size of the Enviro Buildings. No welding of seams shall be required for installation.
SLOPED ROOF PACKAGE
(When specified)
(For use on Enviro Buildings installed outside) (May be required at certain snow loads; consult Enviro Buildings®)
In order to form a sloped roof profile, suitable quantities of sloped foam shall be provided. The foam shall be cut in a manner that upon installation, a ¼”:1′ slope is obtained. The membrane roof shall be increased in size appropriately, in order to provide the additional material required to properly cover the resultant profile.
