Glossary

Air Side

The side of float glass that was up, or exposed to the "air", when it was manufactured. The bottom side is referred to as the "tin" side because it floated on a liquid tin bath. Coatings are applied to the air side.

Air Spacer

A desiccant filled frame used to separate two lites of glass in an insulating unit.

Annealed

Raw glass with low residual stresses. This enables cutting and fabrication.

Argon Gas

An invisible non toxic gas used in insulating units to enhance the units insulating performance (u-value).

Butyl

Shortened term for polyisobutylene. The primary seal of an insulating unit and key component in restricting moisture vapor transmission.

Ceramic Frit

An enamel applied to glass for decorative/aesthetic appearances and/or functionality such as solar control, ceramic frit is applied with a large roller for full spandrel applications or through a screen for silk-screen applications.

Coated Glass

A general reference to any glass incorporating a reflective or low-e coating.

Desiccant

Small extremely porous beads used to absorb moisture in the sealed air spacer of an insulating unit.

Dual Seal

Refers to an insulating unit with a primary seal of polyisobutylene (butyl) and a secondary seal of silicone.

Emissivity

The measure of a surface's ability to emit long-wave infrared radiation.

Float Glass

Glass formed on a bath of molten tin. The surface in contact with the tin is known as the tin surface or tin side. The top surface is known as the atmosphere surface or air side.

Fully Tempered Glass (FT)

Glass that has been heat-treated to have either a minimum surface compression of 10000 psi or an edge compression not less than 9700 psi in accordance with the requirements of ASTM C 1048 kind FT or meet the requirements of ANSI Z97.1 or CPSC 16 CFR 1201 safety glazing standards. Tempered glass is 4-5 times stronger than annealed glass and when broken breaks into small relatively harmless pieces.

Heat Soak

A process of heating glass to a specific temperature for a specified time in a special oven in an attempt to find any impurities in the glass known as "nickel sulfide inclusions".

Heat Strengthened (HS)

Glass that has been heat-treated to have a surface compression between 3500 and 7500 psi and meet the requirements for ASTM C 1048 kind HS. It is ~2-3 times the strength of annealed glass. Heat-strengthened glass is not a safety glazing material and will not meet the requirements of ANSI Z97.1 or CPSC 16 CFR 1201.

Insulating Glass (IG)

Two glass components separated by an air spacer and hermetically sealed. Inherently insulating glass increases a window's thermal performance.

Laminated Glass

Two or more pieces of glass bonded together by a piece of plastic/vinyl called polyvinyl butyral (PVB.) A minimum interlayer thickness of .030 (.76mm) meets the requirements of ANSI Z97.1 or CPSC 16 CFR 1201 safety glazing standards.

Light to Solar Gain Ratio (LSG)

The ratio is equal to the Visible Light Transmittance divided by the Solar Heat Gain Coefficient. The Department of Energy's Federal Technology Alert publication of the Federal Energy Management Program (FEMP) views an LSG of 1.25 or greater to be Green Glazing/Spectrally Selective Glazing.

Low-E

An abbreviation for Low Emissivity coatings. They are applied to glass to reflect invisible long-wave infrared or heat. They reduce heat gain or loss in a building by redirecting the heat. In addition they typically provide greater light transmission low reflection and reduce heat transfer.

Nickel Sulfide

An inclusion in float glass that can cause spontaneous breakage in fully tempered glass.

Offset

Glass unit wherein the two glass ply edges are intentionally not aligned.

Polished Edge

A special fabrication done to the edge of a piece of glass. Makes the edge smooth and gives it an extremely shiny or polished appearance.

Polyisobutylene (PIB)

The primary seal of an insulating unit and the key component in restricting moisture vapor transmission.

Polyvinyl Butyral (PVB)

The plastic or vinyl used in the makeup of a laminated unit the vinyl is what holds that unit together.

R-Value

Thermal resistance of a glazing system expressed ft2/hr/°F/BTU (m2/W/°C). The r-value is the reciprocal of the U-value. The higher the R-value, the less heat is transmitted through the glazing material.

Relative Heat Gain (RHG)

The amount of heat gained through glass taking into consideration the effects U-value and shading coefficient. The English System relative heat gain is calculated as: RHG = (Summer U-value x 14°F) + (Shading Coefficient x 200). The Metric System is calculated as: RHG = (Summer U-value x 7.8°C) + (Shading Coefficient x 630). The lower the RHG the more the glass product restricts heat gain.

Shading Coefficient

Shading coefficient is the ratio of solar heat gain through a specific type of glass that is relative to the solar heat gain through a 1/8"" (3mm) ply of clear glass under identical conditions. As the shading coefficient number decreases heat gain is reduced which means a better performing product.

Sightline for Insulating Glass

Edge dimension of insulating glass covered by spacer and intended to be covered in glazing channel.

Sloped Glazing

Glass units that are glazed more than 15° off vertical.

Solar Heat Gain Coefficient (SHGC)

The portion of directly transmitted and absorbed solar energy that enters into the building's interior. The higher the SHGC the higher the heat gain.

Spandrel

The panel(s) of a wall located between vision areas of windows which conceal structural columns floors and shear walls.

STC Rating

Sound Transmission Class Rating is a single-number rating system for interior building partitions and viewing windows used to categorize acoustic performance. Its original intent was to quantify interior building partitions not exterior wall components. As a result it is not recommended for glass selection of exterior wall applications since the single-number rating was achieved under a specific set of laboratory conditions.

Tin Side

The bottom side of float glass as it was manufactured called "tin side" because float glass rides on a bath of liquid tin while it is being cooled.

Turtle Code

The Florida Marine Turtle Protection law requires architectural glass to transmit no more than 45% of light from inside. The reason, light from a coastal building within 1,000 feet of the seashore attracts marine turtle hatchlings aways from their natural environment at sea.

U-Value

A measure of heat gain or heat loss through glass due to the thermal conductance and the difference in indoor and outdoor temperatures. As the u-value decreases, so does the amount of heat that is transferred through the glazing material. The lower the u-value the more restrictive the fenestration product is to heat transfer; reciprocal of r-value.

Visible Light Reflectance

The percentage of light that is reflected from the glass surface(s).

Visible Light Transmittance

The percentage of visible light (380 - 780 nanometers) that is transmitted through the glass. (Visible light is the only portion of the solar spectrum visible to the human eye.)

Warm Edge

Term used to describe insulating spacer technologies that achieve better center of glass thermal performance (u-value) than a traditional aluminum spacer.
