Re: Lintel Needed Above Glass Block?
In addition to what Dom said:
While the IRC does not address glass unit masonry in much detail, the IBC does address it in more detail.
From the 2006 IBC. (underlining is mine)
- 2110.1 Scope. This section covers the empirical requirements for nonload-bearing glass unit masonry elements in exterior or interior walls.
Think of glass block as being like a window or a door, which are like opening in the wall ... the wall needs to be self-supporting without the window or door installed, same with no glass block installed.
Needs a lintel/shelf angle above it, which means it needs a flashing above the lintel/shelf angle, which means it needs weep holes.
