[GLAZING]{.underline}

**\*\*\*\*\* This guide section can be used for specifying the following
types of glass, which may be used in numerous project applications:**

**Clear Mirror**

**Tinted Heat strengthened**

**Low emissivity Fully tempered**

**Spandrel Laminated**

**Patterned Monolithic**

**Wired Insulating**

**It is convenient and ensures consistency to specify all types of glass
required for a Project in Section 08800, "Glazing". Other sections which
require glazing, such as a window specification, are then cross
referenced to Section 08800, "Glazing". This eliminates the redundancy
of repeating a glass specification in several sections and the inherent
possibility for conflicting information. It also ensures that when
tinted coated glass is used in several products and applications the
glass will be identical in all instances and present a uniform
appearance for the project.**

**This section does not include plastic, bullet resistant, blast
resistant glazing, and factory or site applied films applied to glass to
provide solar control, safety, security, and blast resistance. If
required, these topics can be added to this section or specified
separately in other sections. Generic gaskets, sealants, and other
glazing accessories are included in this section. However, special
applications such as butt glazing, sloped glazing, structural glass
curtain walls, and structural silicone sealant glazing will need to be
added if required for project.**

**The specifier will need to edit this section for a specific project to
reflect the options and applications being used. The guide section has
been written so that most editing can be accomplished by deleting
unnecessary requirements and options. Depending on project requirements,
some additional information will need to be added by the specifier.
Options are indicated by \[ \]. Notes to assist the specifier in
selecting options and editing the specification guide are printed in
bold and indicated with \*\*\*\*\*. For final editing, all brackets and
notes will need to be deleted from the guide and this specification will
need to be made into a Construction Special Specification.**

**Throughout this product guide specification, references are made to
other specification sections that might be contained in the project
manual. These references are presented as examples and coordination
reminders. \*\*\*\*\***

A.  Visible Light Transmittance (T-vis): Percentage of sun\'s visible
    energy transmitted through glass.

```{=html}
<!-- -->
```
N.  Ultra Violet Transmittance: Percentage of sun\'s ultra violet or
    infrared energy transmitted through glass.

O.  U-value: Overall indication of heat flow through glass where a lower
    value indicates less heat flow and hence better thermal performance.
    Winter nighttime values are calculated using outdoor air temperature
    of 0 degrees F, indoor temperature of 70 degrees F, and 15 MPH
    outdoor air velocity. Summer daytime U-values are calculated using
    outdoor air temperature of 89 degrees F, indoor temperature of 75
    degrees F, 7.5 MPH outdoor air velocity, and solar intensity of 248
    BTU.

P.  Shading Coefficient (SC): Ratio of total solar energy passing
    through glass relative to amount passing through 1/8 inch thick
    clear glass under same conditions. A lower coefficient indicates
    better performance in reducing heat gain.

Q.  Solar Heat Gain Coefficient (SHGC): Solar heat gain through glass
    relative to the amount of solar radiation. It is equal to 86 percent
    of the shading coefficient.

R.  Light-to-Solar Gain Ratio (LSG): Ratio of visible light
    transmittance (T-vis) to solar heat gain coefficient (SHGC),
    LSG=(T-vis)/(SHGC). The higher the ratio, the better the glass is at
    reducing unwanted solar heat and maximizing light transmittance.

## 2.02Number range level1Number range level2 PRIMARY GLASS PRODUCTS

**\*\*\*\*\* This article contains primary glass products provided by
manufacturers such as those firms listed in Paragraph 2.1. These
products are typically used by regional fabricators to produce
insulating, laminated, heat strengthened, and fully tempered glass units
in sizes required for a specific project. Fabricators may also be
responsible for field installation of glass or a separate installer may
be used.**

**Clear glass is typically used for interior applications and as the
inside lite of insulating units. Clear glass is also used for exterior
applications where a colored tint is not desired. Include the following
paragraphs to specify clear glass. For thickness other than 1/4 inch,
modify performance attributes. \*\*\*\*\***

**\*\*\*\*\* Many tinted glass products are available from glass
manufacturers. They are used in exterior applications, typically as the
outside lite of insulating units, to provide a distinctive appearance
for the building exterior. Tinted glass has the additional benefit of
reducing glare and solar heat transmission. Most manufacturers provide
tints that are similar to colors provided by other manufacturers
although some tints are distinctive to a single manufacturer. Use the
following paragraphs to specify tinted glass. Select specific tinted
glass and use attributes listed in manufacturer\'s product literature to
establish desired requirements. \*\*\*\*\***

**\*\*\*\*\* Low emissivity (low-E) glass products are produced by
applying to clear glass a neutral coating which blocks a significant
percentage of solar energy and greatly improves energy efficiency.
Typically, low-E glass is combined with either clear or tinted glass and
with or without a reflective coating, to produce an insulating glass
unit. The low-E glass is typically placed as the inside lite of an
insulating unit but can also be used as the outside lite. Refer to
manufacturer\'s product literature for assistance in selecting low-E
glazing options and performance attributes. \*\*\*\*\***

## 2.03Number range level1Number range level2Number range level3 HEAT TREATED GLASS

**\*\*\*\* Clear and tinted annealed glass can be heat treated to
increase strength and resistance to thermal stress. Not all coatings
applied to glass are suitable for subsequent heat treatment and the
specifier should refer to manufacturer\'s product literature for
limitations. There are two types of heat treatment - heat strengthened
and fully tempered. Heat strengthened glass is approximately twice as
strong as annealed glass of equal thickness. However, it does not
qualify as safety glass in compliance with ANSI Z97.1 and CFR 16CFR
1201. Use the following paragraph to specify heat-strengthened glass.
\*\*\*\*\***

A.  Heat strengthened glass: Provide heat strengthened, annealed glass
    components where indicated or required to adequately support imposed
    loads, to allow for large glass size, and resist anticipated thermal
    stresses in accordance with ASTM C1048, Kind HS.

**\*\*\*\*\* Fully tempered glass is approximately four times as strong
as annealed glass of equal thickness. Tempered glass does qualify as
safety glass in compliance with ANSI Z97.1 and CFR 16CFR 1201. Tempered
glass tends to break into small cubical pieces. Use the following
paragraphs to specify fully tempered safety glass. \*\*\*\*\***

M.  Fully tempered glass:

    1.  Provide heat tempered, annealed glass components where indicated
        or required to adequately resist loading conditions, size of
        units, and anticipated thermal stresses in accordance with ASTM
        C1048, Kind FT.

    2.  Fully tempered glass shall meet requirements of ANSI Z97.1 and
        CFR 16CFR 1201 to qualify as safety glass.

## 2.04Number range level1Number range level2Number range level3 LAMINATED GLASS

**\*\*\*\*\* Safety glass can be fabricated by bonding two or more glass
panes with a transparent, flexible interlayment material. Laminated
glass does** **qualify as safety glass in compliance with ANSI Z97.1 and
CFR 16CFR 1201. When broken, laminated glass tends to remain in place
with glass particles adhered to interlayment. Glass lamination is
typically accomplished by fabricators of glass units. Use the following
paragraphs to specify laminated safety glass. \*\*\*\*\***

A.  Laminated glass: Fabricate by bonding two or more glass panes with
    transparent, flexible interlayment material in accordance with ASTM
    C1172.

```{=html}
<!-- -->
```
N.  Laminated glass shall meet requirements of ANSI Z97.1 and CFR 16CFR
    1201 to qualify as safety glass.

## 2.05Number range level1Number range level2 SPANDREL GLASS

**\*\*\*\*\* Clear and tinted glass can be coated on the inside face
with opaque coatings to provide opacity for non-vision areas. The intent
is for spandrel glass panels to match appearance of vision lites. Tinted
glass is used for fabricating spandrel glass as required to match
appearance of adjacent vision lites.**

**There are two methods for fabricating spandrel glass. One is to apply
a black or other colored polyester film to the inside face of a tinted
glass. Spandrel glass can also be fabricated by heat fusing a colored
ceramic frit to the interior surface of clear glass. Due to high thermal
stresses common in opaque glazing areas, it is usual for spandrel glass

## 2.07Number range level1Number range level2 FABRICATED GLASS UNITS

**\*\*\*\*\* The various glass products specified in the above
paragraphs will typically be cut and fabricated into specific glass
products to be used in various applications for a project. These include
monolithic, insulating, heat strengthened, tempered, laminated, and
spandrel units. Each type of glazing unit will need to be described
including thickness and if glazing is monolithic, insulating, safety,
heat tempered, clear, tinted, and low-E coated. It is convenient to
assign type numbers to the various glazing units. In this manner they
can be easily referenced on the drawings. \*\*\*\*\***

A.  Fabricate the following glazing units listed below for use on
    Project using glass products specified in Paragraphs 2.2 through
    2.\[\_\_\_\_\_\]. Refer to Drawings for required sizes and
    locations.

    1.  Thickness: Indicated glass thickness are minimums. Provide glass
        units with thickness as required for glass type, size, and to
        accommodate performance requirements specified in Paragraph 1.4.

    2.  Heat treatment: Provide heat strengthened or fully tempered
        glass units where indicated or as required to accommodate
        performance requirements specified in Paragraph 1.4.

    3.  Clean cut glass units to accommodate opening sizes and edge and
        bite conditions.

**\*\*\*\*\* Use the following paragraphs as a format for specifying
monolithic fabricated glass units. For each type of monolithic glass
unit, include appropriate options and performance attributes.
\*\*\*\*\***

Q.  Number range level3Monolithic glass units:

    1.  Type G\[\_\_\_\_\_\]:

        a.  Type: \[Annealed\] \[Heat strengthened\] \[Fully tempered
            safety\] \[Laminated safety\] glass.

        b.  Thickness: \[\[1/4\] \[\_\_\_\_\_\] inch\].

        c.  Color: \[Clear\] \[\[\_\_\_\_\_\] tinted\].

**\*\*\*\*\* Insulating glass can be fabricated using two glass panes,
referred to as lites, separated by an air space with the interpane space
purged with dry hermetic air and sealed. The air space provides
insulation and reduces heat transfer as well as limiting condensation
and sound transmission. There are numerous insulating glass options
since the units can be almost any combination of clear, color tinted,
low E coated, and spandrel glass products. The specifier will need to
identify the exact type of glass being used for both the outside and
inside lites and list what applied coatings, if any, are being used, and
the surface on which the coating is applied. With a double
pane-insulating unit there are four surfaces:**

**1 - Outside facing surface of outside lite.**

**2 - Inside facing surface of outside lite.**

**3 - Outside facing surface of inside lite.**

**4 - Inside facing surface of inside lite.**

**Thickness of insulating glass varies from 7/16 to 1-1/4 inches. 1-inch
total thickness with two 1/4-inch lites and 1/2-inch air space is
typical.**

**At SNL, anti-intrusion or burglar resistant insulating glass is
accomplished with fully tempered outside lite and laminated inside lite.
\*\*\*\*\***

    5.  Color: \[Clear\] \[\[\_\_\_\_\_\] tinted\].

    6.  Low-E coating on inside face: \[\_\_\_\_\_\].\]

**\*\*\*\*\* Performance values for an insulating unit are a combined
result of the performance attributes of the two glass lites. The
specifier will need to refer to the performance value tables in
manufacturer\'s product literature and select the appropriate values for
the insulating glass unit being specified. \*\*\*\*\***
