TEMPERED GLASSProductionStandard annealed glass is cut to size and fabricated with the specified edge treatment, holes, notches, etc. It is then carefully cleaned and transferred to a tempering oven with oscillating ceramic rollers and heated until it reaches a softening point at approximately 1,200 deg. F. At this critical point, the glass is moved to the “quench” and rapidly cooled by air jets. The process toughens the glass and hardens its surface.

PropertiesTempered glass’ surface (see the Com-pression Zone figure below) is approxi-mately four times stronger than regular annealed glass of the same thickness

Improved resistance to thermal stresses

Breaks into small, relatively harmless, dice-size pieces

Can display a minimal amount of bow, warp, and other characteristic waves and distortions caused by the heating process

Color, chemical composition, and light transmission characteristics – remain unchanged

ApplicationsFloor-to-ceiling glass partitions

Structural glass assemblies

Frameless installations

Doors and sidelites

Large non-adjacent glazed panels

Tub and shower enclosures

Shelving, display cases, and signs

Table tops, fireplace screens, and other applications requiring temperature resistance up to 500 deg. F

Spontaneous Breakage – heat-treated glass will break when the compression layer is penetrated. Spontaneous breakage in fully tempered glass can occur from one or a combination of the following causes:

– Surface or edge damage

– Deep scratches or gouges

– Severe weld splatter

– Windborne debris impact

– Glass to metal contact

– Wind or thermal loading

– Nickel sulfide inclusions – formed when nickel-rich contaminants are unintentionally introduced into the raw glass materials; these inclusions are harmless in annealed glass but can cause spontaneous breakage in tempered glass

Note: Bendheim Wall Systems’ tempered Lamberts channel glass can be 100% heat soak tested to minimize the threat of spontaneous breakage due to nickel sulfide inclusions. Please refer to the Glossary for an explanation of the heat soak process.

BUILDING OCCUPANT SAFETY AND GLASS

Bendheim safety tempered and laminated glasses meet the requirements for ANSI Z 97.1, the Consumer Product Safety Commission Standard 16 CFR 1201, and ASTM C1172.

Glass ceiling featuring Bendheim safety laminated glass

LAMINATED GLASSProductionStandard annealed, tempered, or heat / chemically-strengthened glass lites are carefully cleaned and permanently bonded under heat and pressure using a PVB (polyvinyl butyral) or an EVA (ethylene vinyl acetate) interlayer. Laminated glass can also be produced with a liquid resin poured into the cavity between two glass lites. The resin is typically cured and permanently bonded to the glass using ultraviolet light. Resin interlayers are often used in specialty applications, such as curved units or glasses exhibiting non-uniform thickness or a surface pattern.

ASTM E 1300 – American Society for Testing and Materials’ Standard Practice for Determin-ing Load Resistance of Glass in Buildings. It is used to determine the load resistance (LR) of specified glass types and constructions exposed to uniform lateral loads.

Bent Glass – Flat glass that has been heated to 1,000 – 1,100 deg. F and gravity- or mechanically-formed into a desired shape.

BTU (British Thermal Unit) – The amount of heat necessary to raise the temperature of 1lb of water by 1 deg. F.

Bullet Resistant Glass – Multiple-laminated glass or glass & plastic designed to resist penetration from medium- to super-power small arms and high-power rifles.

Butt Glazing – Installation where the glass is retained at the head and sill, with no structural support on the vertical edges. The vertical joints between the glass lites are typically weather-sealed with silicone. Butt glazed applications may feature exposed edges, often requiring a glass edge specification.

Channel Glass – A translucent U-shaped glass produced in several widths ranging from 9” – 19” and lengths to 23 feet. Channel glass creates uninterrupted walls of glass with minimal framing elements, making it ideal for daylighting applications. For more information, visit www.BendheimWall.com

Chemically Strengthened Glass – Non-safety glass strengthened by chemical ion-exchange. Its surface can be six to eight times stronger than the surface of standard annealed glass of the same thickness; however, it exhibits the same break pattern as annealed glass which creates a greater risk of severe injury.

Color Coated Glass – Back-painted glass for wall cladding applications. Available from Bendheim in a full spectrum of VOC-free colors. Please inquire about our custom color matching service.

Colored Glass – Metal oxides added to the raw glass batch create glass with color extending through its mass. For example, cobalt produces blue glass, chromium – green, silver – yellow, and gold – pink. Visible light transmittance of colored glass varies from 14% to 85%, depending on the hue and thick-ness. Typical float glass colors include amber, bronze, gray, blue, and green. In addition, Bendheim offers an almost unlimited palette of specialty colors in rolled and mouth-blown glasses. Our exclusive line of Lamberts art glass offers a rich, unique aesthetic in a palette of over 500 hues.

CPSC – Acronym for Consumer Product Safety Commission, a U.S. federal agency. The CPSC standard 16 CFR 1201 Safety Standard for Architectural Glazing Materials requires safety glazing in certain hazardous locations and specifies the test criteria and certification for safety glazing materials.

Cullet – Recycled glass breakage added to the raw batch in most glass-making opera-tions. With up to 40% post-consumer content, Bendheim’s exclusive Lamberts channel and textured architectural glasses contain one of the industry’s highest percentages of glass reclaimed from the municipal waste stream.

Deflection – The amount of glass panel bending, perpendicular to its surface plane, under an applied load.

Design Load – A combination of: positive and negative wind loads, thermal loads, snow/ice loads, impact loads, seismic loads, interior pressure loads due to HVAC equipment or building stack effect, dead loads due to glass weight, and live loads. Standard ASCE 7 is the most utilized tool to determine the appropriate design load of a glass product; please refer to the standard for details.

Design Pressure – The specified pressure a

GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY...

glass product is designed to withstand. It is determined by the design load (see previous entry).

Double Glazing – Any use, within an opening, of two glass lites separated by an air space to improve insulation against heat transfer and/or sound transmission.

Etched Glass – Glass is exposed to hydro-fluoric acid in order to etch a silky frosted surface – not to be confused with sand-blasted glass. Etched glass diffuses transmit-ted light and reduces glare, making it an out-standing daylighting material. It is maintenance friendly, resisting permanent stains from water and fingerprints. Unlike sandblasted glass, etched glass can be used in demanding applications such as shower enclosures and building exteriors. Should there be any requirement to apply adhesives, markers, oil or grease to the etched surface, testing must be done to ensure removal is possible. Bendheim is proud to partner exclu-sively with eco-sensitive North American and European etched glass manufacturers.

Fenestration – Any glazed panel, door, window, skylight, or curtain wall unit on the exterior of a building.

Fire-Polished – Describes smooth, glossy glass surface as a result of exposure to intense heat. It is characteristic of mouth-blown, machine-drawn, and float glasses.

Fire-Protection Rating – The period of time a protective glass assembly maintains its ability to confine a fire, as determined by testing.

Fire-Resistance Rating – The period of time a building assembly maintains its ability to confine a fire and continues to perform its structural function, as determined by testing.

Float Glass – Glass with fire-polished sur-faces and uniform thickness floated and formed over a pool of molten tin. It is typically nearly colorless with a slight greenish-blue cast (observable through its edge) and a visible light transmittance ranging from 75% to 92%, depending on its thickness. Float manu-facturing is a highly-automated, 24-hour oper-ation capable of producing up to 800 tons of glass per day.

Fully Tempered Glass – see Tempered Glass

Glass Quality – Float glass and machine-rolled clear patterned glass quality standards are defined by ASTM C 1036 Standard Speci-

fication for Flat Glass. Bendheim Wall Systems’ channel glass is produced accord-ing to the German standard DIN EN 752.7.

Glazing – The installation and weather-sealing of a glass product in a prepared opening.

Heat-Absorbing Glass – Glass (usually tinted) formulated to absorb an appreciable portion of solar energy.

Heat-Soak Testing – Glass is reheated in a special calibrated and inspected chamber to approximately 550 deg. F in order to eliminate glass containing nickel sulfide inclusions which can cause spontaneous breakage. Heat soak testing is recommended for all tempered glasses destined for exterior appli-cations subject to changing temperatures. It is normally not required for interior applica-tions.

Heat Strengthened Glass – Non-safety heat-strengthened glass. Exhibits a surface com-pression between 3,500 and 7,500 psi and an edge compression of 5,500 psi or greater. It is approximately two times stronger than regular annealed glass of the same thickness. Its break pattern is similar to annealed glass. Available from Bendheim for special applica-tions.

Heat Treated Glass – Term can be used for both tempered glass (safety) and heat-strengthened glass (non-safety).

IGU (Insulating Glass Unit) – Two or more lites of glass spaced apart and hermetically sealed to form a single-glazed unit with an air or gas space between each lite. Heat trans-fer and sound transmission are reduced through the glass unit. Many decorative glass types, including Restoration Glass®, can be installed in IGUs to achieve the desired thermal performance and create or maintain the desired aesthetic.

Laminated Glass – Two or more glass lites permanently bonded together with one or more PVB, EVA, or liquid resin interlayers. Meets the requirements for ANSI Z 97.1 and/or CPSC 16 CFR 1201, and is typically labeled with a “safety” logo identifying the fabricator, glass type, and the standard it meets. Addi-tional benefits of laminated glass can include improved UV and sound control. Various dec-orative laminates, including unlimited custom options, are available from Bendheim, visit www.bendheim.com

GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY...

Lite – A pane of glass.

Low-E (Low-Emissivity) – A thermal perfor-mance coating applied to the inside glass face to reflect long wave radiation and restrict heat transfer, thus improving the glass U-value. It is transparent when applied to float glass and iridescent on channel glass. Bendheim’s Lamberts channel glass with a Low-E coating has an approx. U-value of 0.41.

Low-Iron Glass – Also referred to as “opti-cally-clear” glass; a special production using raw materials with naturally low levels of iron oxide for superior, near-colorless clarity and brilliance. Excellent for back-painted glass as it renders truest colors.

Mirror Mastic – A high-performance adhesive for mounting glass mirrors to various interior surfaces, including wood, drywall, metal and painted surfaces. It is flexible and will not become brittle over time. Mirror Mastic is easily applied with a caulk-gun, and provides a strong and permanent bond to most types of mirrors.

Monolithic Glass – Describes a single sheet of glass. Excludes laminated glasses.

Mullion – A horizontal or vertical structural member supporting glass panels or sections of a curtain wall.

Neutral Cure Silicone – A specialty adhesive used in glass wall-cladding installation. It is durable, flexible, and bonds to most sub-strates without priming. When cured, it resists moisture, UV light, and high temperatures.

NFRC – National Fenestration Rating Council. Provides information to measure & compare the energy performance of windows, doors and skylights.

Patterned Glass – Typically a rolled glass with a distinct pattern impressed on one or both surfaces for use in decorative glazing, parti-tion walls & openings. Available in hundreds of varieties from Bendheim, in standard thick-nesses and in “heavy” thickness up to 1/2”.

Relative Heat Gain (RHG) – The amount of heat gain through a glass product taking into consideration the effects of solar heat gain (shading coefficient) and conductive heat gain (U-value). The value is expressed in BTU/hr/ft2 (W/m2). RHG = (14 deg. F x Summer U-value) + (Shading Coefficient x 200 BTUs). The lower the RHG, the greater the glass restricts heat gain.

Rolled Glass – Also called “patterned” and “figured” glass. Flat glass manufactured by forming a ribbon of glass with a pair of machined or engraved forming rolls. The rolls impress their surface pattern into the glass surfaces.

R-Value = Heat (BTU) = (1/R)*A*(Text - Tint) – the thermal resistance of a glazing system mea-sured over 1 hour through a 1 sq. ft. area of the glazing unit for each 1 deg. F temperature difference between the indoor and outdoor air. It is the reciprocal to the U-value. The higher the R-value, the less heat is transferred through the glass.

Safety Glass – Fully Tempered (also referred to as “tempered”) and/or Laminated Glass that meets the requirements for ANSI Z 97.1, the Consumer Product Safety Commission Standard 16 CFR 1201, and ASTM C1172.

Sandblasted Glass – Produced by bombard-ing the glass surface with small hard particles to create a frosted aesthetic. Sandblasting can weaken the glass and creates a surface prone to permanent staining. Maintenance-friendly etched glass has replaced most sand-blasted glass as the industry standard for frosted glass.

Shading Coefficient (S.C.) – The ratio of the solar heat gain through the examined glass unit to that which is transmitted through a single lite of 1/8”-thick clear glass. The S.C. of 1/8”-thick clear glass has a given value of 1.0.

Sloped Glazing – A glass installation at a slope of 15 degrees or more from the vertical. It is often subject to greater solar energy exposure and is more susceptible to impact from falling objects, windborne debris, and snow loads than vertical glazing, requiring the use of heat-treated & laminated glass.

Solar Energy Transmittance – The percent-age of solar energy (ultraviolet, visible light, and near-infrared), from 300 to 2,100 nanome-ters within the solar spectrum, transmitted through the glass.

Solar Heat Gain Coefficient (SHGC) = The solar heat gain entering an area through the fenestration to the incident solar radiation, expressed as a number between 0 and 1. The SHGC measures how well a glass assem-bly blocks heat derived from sunlight. The lower the SHGC, the less solar heat it trans-mits.

GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY GLOSSARY.

Spandrel Glass – That portion of the exterior wall of a multi-story commercial building which covers the area below the sill of the vision glass installa-tion and above the head of the glass installation below.

STC (Sound Transmission Class) – a rating of the ability of a building partition to attenuate sound, measured by the amount of decibel noise reduc-tion at different sound frequencies. The STCs for standard windows typically range from 18 to 38. The STC rating of a standard drywall, in compari-son, is approximately 33. Lamination significantly improves glass STC; increased panel thickness can also enhance sound control.

Structural Silicone Glazing – A system built with glass bonded to the framing members of a curtain-wall using a structural silicone adhesive without the presence of exterior retainers or stops.

Tempered Glass – Also referred to as “toughened” or “fully tempered” glass. It is safety heat-treated glass with a min. surface compression of 10,000 psi or a min. edge compression of 9,700 psi. Its surface is approximately four times stronger than the surface of regular annealed glass of the same thickness. It exhibits a characteristic “dice” break pattern minimizing the risk of serious injury. Meets the requirements for ANSI Z 97.1 and/or CPSC 16 CFR 1201, and is typically labeled with a safety logo identifying the fabricator, glass type, and the standard it meets. A wide range of decorative tem-pered glasses are available from Bendheim.

Toughened Glass – same as Tempered Glass

U-Value – A measure of the heat energy trans-ferred through 1 sq. ft. of glazing for each 1 deg. F temperature difference between the indoor and outdoor air. It is the inverse of the R-value; U = 1/R. A low U-value results in lowered heat transfer across the glass unit, and can be improved by insulation, lamination, and specialty thermal coat-ings.

Visible Light Transmittance (VLT) – The percent-age of visible light (approximately 390 to 780 nano-meters within the solar spectrum) transmitted through the glass. It is determined by the glass color and thickness. Clear float glass has 75% to 92% VLT; colored glass has 14% to 85% VLT.

Wired Glass – Polished-surface / rolled glass con-taining a layer of wire imbedded at its center. It is more brittle than unwired glass of the same thick-ness and is not considered safety glass.
