| 1) specifically, why is the "bite" dimension on a wndw frame important? Fig28.17b 2) the acrylic foam structural glazing tape is | 1) it must be sufficiently deep to hold glass in place 2) a 2 sided, pressure-sensitive, closed-cell acrylic foam used to bind a wid variety of dissimilar mat.'s; it's a foam tape to attach glass to framing |
| 1) the req.'d thkns of ext. glass depends on: 2) for glass used in fire-resistance rated partitions, IBC differentiates btwn: | 1) the size of the glazed unit & wind loading, tables in bldg codes give min thkns & max areas based on float glass w/ factor adjustments off this base for oth types 2) fire-protection-rated glazing & fire-resistance-rated glazing |
