    Windows next to Firewalls 706.5

    Per 706.5 it seems the only way to terminate the firewall at the exterior wall and have windows within 4' of the firewall is to sprinkler the building that will have the window within 4'. I am working on non-sprinklered townhomes and they are designed to have the openings within 4'. I think the...
