Safety Glass ? A strengthened or reinforced glass that is less subject to breakage or splintering, such as glass for storm doors and some windows.
Sash - The part of the window which contains the glass.
Sash Balance ? A device for counter balancing a sash of a double hung window to hold it in an up position. There are four basic types:
- Block & Tackle - Sometimes referred to as string balance. A type of balance that employs a block and tackle apparatus and coiled spring. This type balance allows the sash to be easily removed from the window frame. A block and tackle balance can normally carry a heavier load than a spiral or friction balance.
- Spiral ? A balance using a spirally-wound spring.
- Spring ? A balance using a spring for counter-balancing; introduced in the 1980?s.
- Constant Force ? A coiled steel tape under spring tension for balancing the sash, located in the head jamb of the window frame.
- Counterweight ? The most common type of balancing system in older homes, utilizing a weight held by a sash rope or chain over a pulley.
Sash Cord ? In older windows, the rope used to connect the sash with its counter weights.
Sash Lock ? Generally a cam-action type lock applied to the rails of a window or at the open edges of a projecting window to pull rails tightly together or to seal the sash tightly to the frame, both for security and weather tightness.
Sash Stop ? A molding that covers the joint between window sash and the jamb. Often limits sash travel.
Sealant ? A compressible plastic material used to seal any opening or junction of two parts, such as between the glass and its sash, commonly made of silicone, butyl tape or polysulfide.
Seal Failure (Hermetic Seal Failure) ? The failure of the seal or seals in an insulated glass lite. Evidence of seal failure is usually dirt, dust or the appearance of water vapor within the insulated glass unit.
Seat Board ? A flat board cut to fit the contour of a bow or bay window and installed between the sill and the flat wall surface, providing a seat of shelf space.
Shims ? Wood wedges (often wood shingles) used to position on the window or door unit in a rough or masonry opening in a square, level and plumb position during (and after) installation.
Side Jamb ? The upright vertical member forming the sides of the frame of a window or door unit.
Sill - The horizontal, bottom section of the main frame.
Single Hung - A window in which one sash slides vertically and the other sash is fixed.
Single-Strength Glass - Glass with a thickness of approximately 3/32" (2.5 mm).
Slider Window - A window in which the sash move horizontally. Sliders are available in a 2- or 3-lite configuration, with the 3-lite having operable end vents. |
