Safeguard
Another Chrysler brand identifier - see MOPAR.
Safety Glass
Glass which has been treated using processes, such as laminating or tempering, that should result in reduced risk of injury when broken.
Sandblasted Finish
A surface treatment for flat glass obtained by spraying the glass with hard particles so as to clip out and roughen one or both surfaces of the glass. The effect is to increase obscurity and diffusion, but can make the glass fragile and hard to clean.
Sash
The frame, including muntin bars when used, and including the rabbets to receive lites of glass, either with or without removable stops, and designed either for a face glazing or channel glazing.
Scratch
Damage to the glass surface in the form of a line with length but little or no appreciable width.
Scratch (in coating)
A void in the coating which has length but little or no appreciable width.
Sealant
Compound used to fill and seal a joint or opening, as contrasted to a sealer which is a liquid used to seal a porous.
Shaded or Shade Band
An area at the top of the windshield where the vinyl inner layer has been tinted to reduce glare.
Shading Coefficient
Is the ratio of solar heat gain passing through a glazing system to the solar heat gain that occurs under the same conditions if the window were made of clear, unshaped double strength window glass. The lower the number, the better solar shading qualities of the glazing system.
Shelf Life
Used in the glazing and sealant business as referring to the length of time a product maybe stored before beginning to lose it's effectiveness. Manufacturers usually state the shelf life and the necessary storage conditions on the package.
Sidelite
Side glass part which is not part of a door and is usually tempered safety glass.
Sight Line
Imaginary line around the perimeter of lites or panels corresponding to the top edge of stationary and removable stops, and the line to which sealants contracting the lites or panels are sometimes finished off.
Single Glazing
A single pane of glass.
Sleeves
Corrugated envelopes used for the individual packaging of tempered glass.
Sliders
Usually refers to the sliding back glass assembly in pickups, and van windows with movable section(s) that slide (to open or close) in a track instead of being hinged or being part of a mechanism used to "roll" the part up or down.
Sloped Glazing
A single pane of glass.
Solar Glass
(or Solar Control Glass) Manufacturers term for glass that has been treated or specially tinted during the production process to reduce the sun's rays to protect, and reduce heat buildup in the vehicle interior.
Spacers
(Shims) Small blocks of composition, neoprene, etc., placed on each side of lites or panels to center them in the channel and maintain uniform width of sealant beads. Prevent excessive sealant distortion.
Spandrel
That portion of the exterior wall of a multistory commercial building that covers the area below the still of the vision glass installation and the area above the head of the glass installation below.
Spandrel Glass
Heat-strengthened flat glass with a colored-ceramic coating adhered to the back by a heat fusion process. It has double the strength of annealed glass of the same size and thickness, enabling it to withstand greater uniform loads and thermal stresses. Spandrel glass cannot be re-cut after heat strengthening. It is used as fixed opaque colored glass on buildings in front of floor slabs and columns. It is available in a wide array of colors.
Sputter Coating
A micro-thin metallic oxide coating vacuum-deposited on the surface of glass after manufacturing . Sputter coatings are vulnerable to moisture and abrasion and must be enclosed in sealed insulating window units.
Stain
Attack of a glass surface by water or other solutions involving:
A. Leaching of sodium ions to the surface of the glass.
B. An increase in pH on the glass surface.
C. The breaking of silica bonds in the glass structure.
If this process advances to c, the glass will have blotched, streaked, cloudy appearance and cannot be restored to pristine condition short of grinding and polishing the damage away, a process that is generally more expensive than simply replacing the glass.
Stones
Crystalline contaminations in the glass, usually pieces of undissolved or crystalline silica, bits of refractory, or crystals due to devitrification. Stones are detrimental to appearance and may seriously weaken the glass, particularly if present in highly stressed areas.
Structural Glazing
Is based on the use of a sealant not only as a weather seal but also for the structural transfer of loads from the glazing panel to its perimeter support system. Only certain specific sealant formulations are suitable for this purpose.
Structural Glazing Gaskets
Cured elastomeric channel-shaped extrusions used in place of a conventional sash to install glass products onto structurally sprouting sub-frames, with the pressure of sealing exerted by the insertion of separate lockstrip wedging splines.
