Sash
The sash is the part of a window that moves up and down (hung, double-hung windows). It is the frame that holds the glass in place. The vertical sides of the sash are called stiles, and the horizontal top and bottom are called rails. If the window is split horizontally, the vertical strip that divides the 2 panes (lites) of glass is called and mullion, muntin or a glazing bar. More about window sashes.

SDL
SDL is an acronym for "simulated divided lite". A window grill profile is placed on both the outside and inside of a window to give it a traditional look.
Sealant
A sealant used in an edge seal structurally bonds the glass panes and spacer bar together while providing a high level of moisture vapour and gas diffusion resistance and allowing flexion to accommodate glass movement. Polyisobutylene (PIB) is typically used as a primary sealer and Polyurethane (PU), silicon (Si) and polysulphide (PS) are widely used as secondary sealants. Hot-melt butyl or epoxy-based sealants are also used for secondary sealants.
Self-cleaning window
A unique treatment that allows the glass to break down organic dirt that collects on the OUTSIDE surface. Dirt washes away with the next rain or hosing, leaving no streaks or spots. Pilkington Activ™ Self-Cleaning Glass is available in every North Star window as an option. More about self-cleaning windows.
Shaped Window

Sheathing Membrane:
A sheet of synthetic material or bituminous paper designed to shed rain-water. Usually placed between the wall-sheathing and the exterior cladding.
Sidelites
Narrow fixed units mulled or joined to operating door units to give a more open appearance.
