Sonoglass® is a fiberglass based, spray applied acoustical treatment designed to provide superior acoustical values with a finished appearance. Sonoglass® will adhere to almost any surface configuration. This makes it ideal for applications to curved and irregular shaped ceilings such as those found in churches, gymnasiums and theaters. With only a thin application of Sonoglass®, noise reverberation times can be greatly reduced, improving audibility and comfort at a reasonable cost
- Flatter more uniform finish than standard spray-applied acoustic insulation
- More economical than many cellulose-based acoustic finishes
- Improved noise reduction capabilities
- Less material required for effective sound control
- Zero Flame Spread and non-combustible for safety
- Adds to thermal value with R-3.733 / inch
- Conforms to virtually any surface configuration
- Can be painted or tinted
- Contains a minimum of 25% recycled material
- Low VOC content: Sonoglass complies with California Dept. of Public Health CDHP Standard Method V 1.1 for low emitting materials
- Does not support mold growth
Sonoglass Spray Applied Acoustic Treatment exhibits the following properties.

Improved Noise Reduction Properties
With only a thin application of Sonoglass, noise reverberation time can be greatly reduced, improving audibility and comfort at a reasonable cost.
Sonoglass is a fiberglass based, spray applied acoustical treatment designed to provide superior acoustical values with a more finished appearance than our standard Monoglass Spray-On insulation.
Sonoglass will adhere to almost any surface configuration. This makes it ideal for applications to curved and irregular shaped ceilings such as those found in churches, gymnasiums and theaters.
