International RESIDENTIAL Code is 24 inch at the sill. For a change of use to COMMERCIAL, the IBC is 36 inch at the sill.
JeldWen and Silverline have the WOCD built into the top sill.
Mathews Brothers have the WOCD built into a balance cover.
For any of the above when two identical windows exist, the WOCD can be moved without removing the window frame.
For the Mathews Brothers, even if the two windows are simply sized the same... the balance cover can be removed and inserted into the other window's channel.
WOCD must be factory installed from Marvin, Andersen, and JeldWen wood windows... after market retrofit devices void the warranty.
The programs we use ''scream'' at us whenever we try to do anything that doesn't meet code. Site changes is what we cannot control... those are the BCI. While some may ''overlook'' it, I can't imagine that the number of different jurisdictions that we sell into not one would be found.
WOCD registers a ''flag''. You cannot just skip past that question.
Tempered glass or Egress do not.
