Can I Cover Up Acoustic Ceiling Tiles With Drywall?

Covering aluminum acoustic ceiling tiles with drywall is not advisable if you intend to preserve their sound-absorbing function. Drywall acts as a dense barrier, reflecting rather than absorbing sound, effectively negating the acoustic benefits of the perforated aluminum panels beneath. Additionally, the added weight of drywall requires reinforcing the suspension grid and ceiling structure to prevent sagging or collapse. Instead of full drywall overlay, consider installing gypsum board panels in separate framing below the acoustic system, creating a double-ceiling design. Maintain a gap between the drywall and acoustic tiles to allow sound absorption by the underlying insulation. Alternatively, use ceiling tiles with integrated decorative finishes—such as pre-finished gypsum-faced aluminum panels—that offer both sound control and a smooth, drywall-like appearance. For minimal visual transition, choose aluminum acoustic tiles with micro-perforations and matching aluminum trim profiles. These approaches ensure you retain acoustic performance while achieving a unified ceiling aesthetic without the structural and acoustic drawbacks of covering tiles with traditional drywall.
