R609.7.2.1

Section 609.7.2.1 is titled 'Masonry, concrete or other structural substrate' and covers requirements for exterior windows and doors. The requirement to anchor window and glass door assemblies in a specific manner detailed in cross-referenced figures in this code, dependent on the thickness of the shim or buck is established. The purpose of this section is to prevent detachment of windows and glass door assemblies from the building.

The model shows 2 examples of concrete wall sections with a window. The 1st example has the window attached directly to the concrete and the 2nd utilizes a 2X wooden buck.
