Install Pebble™ Fiberglass 2’ x 4’ fiberglass ceiling panels when you want a lightweight, easy-to-handle alternative to traditional mineral fibre drop ceiling material. The fiberglass material provides you with an easier installation. Why? Because fiberglass panels give you flexibility in tight spaces, such as around pipes and ductwork. Pebble panels have a large grit visual, and high light reflectance, making your space bright. Plus, panels are acoustical, which helps to reduce noise to make your space quiet. They also have superior sag and mold resistance – perfect for your basement. You can easily install them in 15/16” suspended grid.
