Sound Control Where You Need It:
• Commercial Buildings
• Residential Structures
• Media Rooms
• Home Offices

The millions of semi-rigid open cells in Demilec's SEALECTION® 500 insulation work to absorb sound waves at varying frequencies, making it possible to design cost effective walls and ceilings with a Sound Transmission Class (STC rating) of 50 or more. Houses, buildings, and rooms insulated with SEALECTION® 500 all enjoy the benefit of protection against unwanted noise!

With a STC rating of 50, our walls don’t talk. Ceilings and walls were meant to absorb sound, not make it. This is exactly what SEALECTION® 500 spray foam does. Versatile enough to use in both standard and nonstandard geometric designs, like curved walls and odd-sized wall cavities, SEALECTION® 500 is a quiet design built right in.

A fairly quiet room has between 30-50dB of background noise. Typical wood stud construction using fiberglass insulation and 5/8” drywall on both sides has an STC rating of 27-34. A home theatre boosts up to 100dB, which means the system would produce an overwhelming 70dB of sound in a typical wood stud construction room. However, a wall insulated with SEALECTION® 500 (under the same condition) would produce around 50dB. That’s 75% quieter!
