Soffit panel attachment system

A soffit lining system, comprising:

• a first soffit panel attachment device coupled to a building substrate, the first soffit panel attachment device comprising a first attachment surface lying adjacent to the building substrate, a first central portion perpendicular to the building substrate and coupled to the first attachment surface at a first end of the first central portion, and a first plurality of flanges extending from the first central portion at a second end of the first central portion opposite the first end, the first plurality of flanges disposed parallel to the first central portion to form a first U-shaped channel aligned with the first central portion and opening away from the building substrate;
• a second soffit panel attachment device coupled to a framing member spaced outwardly from the building substrate, the second soffit panel device comprising a second attachment surface lying adjacent to the framing member, a second central portion parallel to the first central portion and coupled to the second attachment surface at a first end of the second central portion, and a second plurality of flanges extending from the second central portion at a second end of the second central portion opposite the first end, the second plurality of flanges disposed parallel to the second central portion to form a second U-shaped channel aligned with the second central portion and opening toward the first U-shaped channel, wherein the second soffit panel attachment device comprises a plurality of openings extending through the second central portion;
• and
• a soffit panel having a substantially planar surface comprising a first edge and a second edge opposite the first edge, the soffit panel disposed at least partially within the first and second U-shaped channels, the first edge being disposed within the first U-shaped channel and resting on one of the first plurality of flanges, the second edge being disposed within the second U-shaped channel and resting on one of the second plurality of flanges, such that the first and second soffit panel attachment devices support the soffit panel along a length of the soffit panel.
