About Selecting Thermal Insulation

The best sound absorbers of all our rigid sheets, use to quiet noisy areas in your facility. They're peaked on one side for more sound-absorbing area than flat sheets. Made of melamine, they have an acrylic resin finish that resists dust and dirt and wipes clean.
