The interior edge detail where glazing meets wood is called sticking, sometimes referenced as bead. While ovolo sticking is usually featured, square sticking can be specified for a clean, crisp, more contemporary look. Simulated divided lite bars in products with square sticking echo the design and share square profiles.
Square sticking is unavailable on IZ4 and fire-rated units, those with authentic divided lite, or with single glazing, and Tilt Pac units.
