Once the horizontal lines have been cut, make verti- cal cuts using the inside edge of the studs as a guide. Once you have made both vertical cuts, you should have a rectangular hole in the sheetrock. Now you have to make the same hole on the other side of the wall.

Using two 2x4s at 14.5” in length and eight 6d nails, secure the upper and lower supports to the right and left studs, just inside the sheetrock. Make sure that the internal height remains at 16” so that the WhisperKOOL system will fit snugly through the framed
Frame the hole with two-by-four supports
