1. A method of installing and retaining insulation relative to at least one of a mullion and a transom having a given width, the method comprising:
using a fastener to attach to a side surface of the mullion or transom a side plate of each of a plurality of spaced apart L-brackets, each said L-bracket having a first receiving slot formed in the side plate;
positioning the insulation in a space adjacent to at least one of the mullion and the transom;
engaging with each L-bracket a clip having a pair of clip legs with a first of the pair of clip legs extending through the first receiving slot of the L-bracket and a second of the pair of clip legs penetrating into the insulation, wherein at least one of the clip legs has a tapered free end.
 
17. A wall system, comprising:
a plurality of L-brackets that are spaced apart from each other;
a fastener configured to attach to a side surface of a mullion or transom a side plate of each L-bracket of the plurality of L-brackets, said L-bracket having a first receiving slot formed in the side plate;
a clip configured to engaged said L-bracket, the clip having a pair of clip legs with a first of the pair of clip legs configured to extend through the first receiving slot of the L-bracket and a second of the pair of clip legs configured to penetrate into insulation, wherein at least one of the clip legs has a tapered free end;
wherein the L-bracket includes a flange extending perpendicular to the side plate, the flange having a second receiving slot formed therein that is sized and shaped to slidingly receive a vertical face plate of a stiffener, the second receiving slot being formed by a portion of each flange that is cut and raised from a surface of the flange.
