Bear Glass

Safety Glass - Glass which must have passed an impact test and either must not break or must break safely.
Safety Glass - Glass which does not disintegrate into sharp and potentially dangerous splinters when it is broken. Safety glass may be produced by laminating (see "laminated glass") or by tempering (see "tempering").
Sand-blasted glass - This type of glass is produced by spraying sand at high velocities over the surface of the glass.
Sandblasting - A method for giving glass surfaces a matt finish either for decoration or to reduce transparency. Compressed air forces the abrasive material through the nozzle of a sandblasting gun and onto the glass surface. The glass is normally placed inside a special cabinet with arm holes, a viewing window and dust extraction facilities.
Sandblasting - A special glass treatment in which sand is sprayed at high velocities over the surface of the glass.
Screen printed glass - Screen printed glass is tempered or heat-strengthened glass, one face of which is covered, either partially or totally, with mineral pigments.
Sealant - A flexible material for sealing.
Sealed Double Glazed Unit - A combination consisting of two glass panes enclosing a hermetically-sealed air space.
Sealer - A substance applied to glass and frame surfaces that guarantees consistent adhesion.
Secondary seal - A sealant applied to the edges of double-glazed units after the primary seal, to provide effective and durable adhesion between the glass components and spacer bar.
Self cleaning glass - This type of glass is covered by a special coating which literally cleans itself.
Sheet Glass - A lite of glass.
Sight size - The actual size of the opening that admits daylight.
Silicone - A polymeric organic compound offering excellent resistance to cold, heat and water.
Silicone - used principally as adhesives and setting materials, particularly where plasticity or water-repellent characteristics are required.
Silvering - is the chemical process of coating glass with a reflective substance to create a mirror. When this substance is applied to the glass a chemical reaction takes places, bonding the silver to the glass. The mirror is dried and coated with a special back paint.
Single glazing - Window or door with a single glass lite.
Single-strength glass - A term used to describe glass with a defined thickness (2.16-2.57 mm).
Snow load - An imposed load exerted onto a structure by formation of snow.
Space bar - Generally an aluminum bar along all edges of a double-glazed unit, filled with desiccant, which separates the two panes of glass and creates a cavity.
Spacer -A metal bar or strip, generally of aluminum, which is bent into a frame to separate the two panes of glass in an insulating glass (I.G.) unit.
Spall - Small fragments of glass that are ejected from the surface of a laminated glass sheet when the opposite surface is impacted.
Sputtering - Is a method better known as "vacuuming" to apply coating on the glass.
Structural sealant glazing - An external glazing system where the glass is bonded to a carrier frame without mechanical means.
Surface Coatings - A thin layer or covering which changes the basic composition of glass.
