The Sona-Spray acoustic treatment is comprised of high quality virgin paper stock, chemically treated to be Class I fire rated, then blended with an advanced vinyl adhesive to provide a strong durable acoustic product that will absorb as much as 95% of the sound that comes into contact with it.

The benefits of Sona-Spray include:

• Strong durable finish.
• Conforms to any surface design including glass.
• 80% light reflective surface.
• Many design options.
• Can be color matched to surrounding finishes.
• Lower cost than competing products.
• Quick application / 3000 square feet per day.
• Resists ball damage in gymnasium.
• Will not crack or flake.
• Recycled product.
• Completely non-toxic.

The Sona-Spray is so compatible with construction design that the Historic Society has even approved it for a "turn of the Century" courtroom.  When color matched to surrounding structure, Sona-Spray is virtually unnoticeable, except of course for the dramatic improvement in reverberation times and sound levels.

Sona-Spray is truly a revolutionary acoustic product and Retrotherm takes extreme pride in each and every application.  Retrotherm commonly extends their warranty to 10 years to prove to customers that this product will withstand the test of time and will not be damaged by general abuse.
