A method of covering a ceiling support with a plurality of ceiling panels, each of the ceiling panels comprising an upper face, a lower face opposite the upper face, a first edge, a second edge, a third edge opposite the first edge, and a fourth edge opposite the second edge, each of the first and second edges comprising a tongue, and each of the third and fourth edges comprising a groove, the method comprising:
- a) mounting the ceiling panels to the ceiling support in an interlocked arrangement so that the tongues of the ceiling panels nest within the grooves of adjacent ones of the ceiling panels, the ceiling panels mounted so that the upper faces of the ceiling panels oppose a lower surface of the ceiling support;
- and
- b) during step a), positioning an alignment clip having a cruciform rib element at an intersection of four of the ceiling panels, the cruciform rib element of the alignment clip maintaining the four ceiling panels in orthogonal alignment with one another.
A ceiling panel comprising:
- an upper face;
- a lower face opposite the upper face;
- a first edge, a second edge, a third edge opposite the first edge, and a fourth edge opposite the second edge;
- wherein each of the first and second edges comprise a tongue;
- and each of the third and fourth edges comprise a groove;
- wherein each of the first, second, third, and fourth edges comprise a first edge portion adjacent the upper face and a second edge portion below the first edge portion;
- wherein the second edge portion of each of the first and second edges comprises the tongue;
- the second edge portion of each of the third and fourth edges comprises the groove;
- the first edge portion of each of the third and fourth edges comprises a first flange that terminates in a distal surface;
- the first edge portion of each of the first and second edges comprising a first recess comprising a first recess wall surface and a first recess floor surface;
- wherein the first flanges is configured to be able to nest within a first recess of an identical adjacent ceiling panel.
