Abstract: A construction system including a panel support accessory is disclosed. In addition to the panel support construction accessory, the construction system includes at least one structural support member, a construction panel and a coating. The panel support construction accessory includes a front flange having a first side and a second opposite side, a bottom flange extending from the front flange on the first side of the front flange and a back flange extending from the bottom flange opposite the front flange. The front flange, the bottom flange and the back flange form a channel. The back flange is supported by the at least one structural support member. The panel support construction accessory additional includes a forward flange extending from a junction of the front flange and the bottom flange on the second side of the front flange.

Abstract: A construction system includes an accessory and a construction panel. The accessory includes a first flange, a second flange and a third flange extending between the first flange and the second flange. The first flange, the second flange and the third flange form a channel. The construction panel is at least partially disposed within the channel. The third flange includes a plurality of perforations extending therethrough. In one embodiment, the plurality of perforations extend in an array. In another embodiment, the accessory additionally includes a fourth flange facing the third flange and spaced from the third flange to form a cavity between the third flange and the fourth flange adjacent to the plurality of perforations.
