B. Field Measurements: Verify actual dimensions of openings for display system by field measurements before fabrication.

PART 2 - PRODUCTS

2.1 MANUFACTURERS

A. Source Limitations: Obtain display system from single source from single manufacturer.

2.2 PERFORMANCE REQUIREMENTS

A. Surface-Burning Characteristics: Comply with ASTM E 84; testing by a qualified testing agency.

Identify products with appropriate markings of applicable testing agency.

1. Flame-Spread Index: 25 or less.

2. Smoke-Developed Index: 50 or less.

B. Electrical Components: Listed and labeled as defined in NFPA 70, by a qualified testing agency, and marked for intended location and application.

2.3 DISPLAY CASE

A. Basis of Design: Subject to compliance with requirements, provide Recessed, Custom Wall Display by Helmut Guenschel, Inc, or approved equal by Schmitz & Schmitz.

B. Operable glass door panel display frontage system including a structural frame

(steel “C” channel), top and bottom, operable hinged glass panels and appropriate mounting hardware; dust minimizing seal package is to be included.

1. Frameless construction with no intermediate vertical support.

2. In closed position, adjacent glass panels shall remain in one plane. Adjustable alignment pins shall assure that the glass is properly closed and positioned.

3. Structural components shall not be visible, fasteners shall be concealed and locking is provided by means of pin tumbler cylinder locks.

4. Interior Panel Finishes: Wood Laminate Panels. Layout as indicated on drawings.

a. Panel laminate as selected by Architect.

5. The glass panels will be 12mm thick low-iron laminated safety glass (anti-reflective glass is optional at an additional charge) mounted into aluminum rails top and bottom;

vertical glass edges are precision-ground and polished.

6. Laminated glass for display doors in lieu of tempered: Important safety feature which protects both building occupants and artifacts in the event of breakage. The interlayer between the lites is a natural UV filter, which will protect artifacts, documents and photographs from fading. Included seal package to make the display cases virtually dust and maintenance free, reducing requirements for interior cleaning.

C. Hinges: Dual actuated hinges manufactured from high-strength aircraft aluminum and requiring no lubrication. When unlocked, the door panel releases from the compression seal and rotates out and away from the display space providing full access. The pivot end of the panel does not rotate into the display space.

a. The operable door panels are equipped with heavy-duty hinges in high strength
