SECTION 08411 - ALUMINUM ENTRANCES AND STOREFRONTS (FLUSH GLAZE AND E-Z SET SYSTEMS)

*************************************************************************************************

This guide specification has been prepared by Vistawall Architectural Products in printed and electronic media as an aid to specifiers in preparing written construction documents for storefront systems.

This section includes aluminum doors, door frames and glazed lights for exterior and interior applications, shop fabricated, factory pre-finished, for field glazing. The system application is less than one story, usually from floor to spandrel beam above or less in height.

Door hardware may be specified in whole or in part in this section or in Section 08710 - Hardware; coordinate requirements.

Sealants are referenced to Section 07900, Sealants Sealers.

Glass and glazing are referenced in Section 08810, Glass and Glazing.

Where work of this section integrates with curtain wall, sloped glazing system, skylight, windows, or other glazing system, carefully coordinate both sections to function together. Air and vapor barrier continuity from this system to adjacent construction is critical to successful building air tightness; specify compatible materials in conjunction with adjacent air and vapor barriers.

Edit entire master to suit project requirements. Modify or add items as necessary. Delete items which are not applicable. Words and sentences within brackets [_____] reflect a choice to be made regarding inclusion or exclusion of a particular item or statement. This section may include performance, proprietary, and descriptive type specifications. Edit to avoid conflicting requirements.

*************************************************************************************************

Use the article below carefully; restrict statements to describe components used to assemble the system. Do not repeat statements made in the SECTION INCLUDES article. Restrict statements to identify system performance requirements or function criteria only. Delete paragraphs not appropriate to project.

The following paragraphs represent a suggested listing of performance criteria.

*************************************************************************************************

1.03 SYSTEM REQUIREMENTS

A. Design Requirements:

1. Drawings are diagrammatic and do not purport to identify nor solve problems of thermal or structural movement, glazing, anchorage, or moisture disposal.

2. Requirements shown by details are intended to establish basic dimension of units, sight lines and profiles of members.

3. Provide concealed fastening.

4. Provide entrance and storefront systems, including necessary modifications, to meet specified requirements and maintaining visual design concepts.

5. Attachment considerations are to take into account site peculiarities and expansion and contraction movements so there is no possibility of loosening, weakening or fracturing connection between units and building structure or between units themselves.

6. Anchors, fasteners and braces shall be structurally stressed not more than 50% of allowable stress when maximum loads are applied.

7. Provide for expansion and contraction due to structural movement without detriment to appearance or performance.

8. Assemblies shall be free from rattles, wind whistles and noise due to thermal and structural movement and wind pressure.

9. Not Permitted: Vibration harmonics, wind whistles, noises caused by thermal movement, thermal movement transmitted to other building elements, loosening, weakening, or fracturing of attachments or components of system.

*************************************************************************************************

6.24 psf is equal to a 50 mph wind. 0.06 cfm/sq. ft. is industry standard. High performing systems (up to 0.01 cfm/sq. ft.) are available at additional cost.

*************************************************************************************************

B. Performance Requirements:

1. Air infiltration: Air leakage through fixed light areas of storefront shall not exceed 0.06 cfm per square foot of surface area when tested in accordance with ASTM E283 at differential static pressure of 6.24 psf.

2. Water infiltration: No uncontrolled leakage when tested in accordance with ASTM E331 at test pressure of 6 psf, or 20% of full positive design wind load, whichever is greater.

C. Thermal Requirements:

1. Framing systems shall accommodate expansion and contraction movement due to surface temperature differentials of 180°F without causing buckling, stress on glass, failure of joint seals, excessive stress on structural elements, reduction of performance, or other detrimental effects.

2. Ensure doors function normally within limits of specified temperature range.

*************************************************************************************************

Coordinate wind loads with applicable building code, or appropriate wind loads may be determined by using ANSI A58.1-1982, "Minimum Design Loads for Buildings and Other Structures". Edit following paragraph accordingly.

*************************************************************************************************

D. Structural Requirements, as measured in accordance with ANSI/ASTM E330:

1. Wind loads for exterior assemblies:

a. Basic loading:

1) [_____] psf acting inward.

2) [_____] psf acting outward.

*************************************************************************************************

In cases of large spans, calculate maximum deflection and give consideration to visual impact. If it appears desirable, specify an allowable deflection less than 1/175 of clear span. Smaller deflections, however, will often require use of heavier cross sections or internal reinforcements. Therefore, importance of visual impact must be weighed against added cost.

*************************************************************************************************

2. Deflection: Maximum calculated deflection of any framing member in direction normal to plane of wall when subjected to specified design pressures shall not exceed [1/175] [___] of its clear span or [3/4] [___] inch, whichever is less [, except that maximum deflections of members supporting plaster surfaces shall not exceed 1/360 of its span].
