Can I use the 24x48 tiles in a 2x2 grid?

Only by cutting them. B is made for a 2x4 layout in a 15/16 inch grid; A drops straight into 2x2 openings.

Which absorbs sound better?

B publishes NRC 0.55 and CAC 35. A's listing gives no sound figures, so B is the safer pick where noise matters.

Are they the same material?

Yes. Both are Cortega mineral fiber panels in 5/8 inch thickness with a white, non-directional face.

Which is easier to install alone?

A. The 2x2 panels are lighter and shorter, so one person can set them overhead without wrestling 4-foot boards.

Do both meet fire code?

A is sold as a Fire Guard product. B states ASTM E84 Class A performance certified by UL. Confirm with your local code official.
