Barrier Composites

Our masticated sheets and rolls are fiber reinforced and fully cured. This unique process translates into higher tensile strength, tear strength, resilience, wear characteristics, ozone resistance, low temperature resistance, and ultimately, durability.

Replacing normal plywood with Noiseless Wood improves the transmission loss in two critical regions. First: at the resonance frequencies of the structure the peak vibration levels are reduced about 10 fold. Second: at mid to high frequencies there is a phenomenon referred to as the coincidence frequency. This is the sound that has the same wavelength in air, as does the bending wave in the panel at the same frequency.

Noiseless Metal (NM) is laminated metal designed to reduce vibrations and noise transmission in metal constructions. It consists of two sheets of metal bonded together by a thin viscoelastic damping layer. NM can be made using any commercial quality steel or aluminum.

Most of the floormats have the same basic composites that give high noise transmission loss as well as a handsome finished appearance for the interior of vehicle cabs. Instead of a cheap open cell underlay, dB Engineering uses a high quality closed cell that performs better at low frequency and does not allow water to soak into the material. The other two composites include a one pound per square foot barrier and a non-slip surface.

dBmat is a noise control material specifically designed to achieve maximum attenuation over a broad frequency range. dBmat combines dense, limp, flexible, non-lead loaded barriers with dBcloth foams providing a total noise control system. Unlike other composites available, these multilayer systems are manufactured without costly adhesives, thus eliminating the potential for failure between layers.

Barrier materials block noise. Flexible noise barrier is a limp, tough, high-temperature-fused vinyl loaded with non-lead fillers and/or reinforced with high-strength fabric. They resist passage of sound waves and reduce noise transmission.

ShurStep provides maximum skid resistance on a wide variety of floor types and surfaces, including the powder-coated paint finishes found on lawnmowers, truck beds, snowmobiles and other commercial products.

dBmat WM1 is a barrier layer of dBmat cured to a single layer of dBcloth acoustical foam. When the dBmat is applied to sheet metal, plastic or wood, the foam is exposed to absorb airborne noise.

dBmat WM2 is a sandwich composite incorporating 2 layers of dBcloth acoustical foam and a single barrier septum. When applied to sheet metal, plastic or wood, the decoupling foam layer typically ¼"(6mm) thick isolates the barrier while the thicker absorption layer reduces airborne reverberant noise.

dBmat Safe and Sound combines a specially formulated barrier with high temperature melamine foam. The mechanical bond between foam and barrier is formed as the barrier is cured, eliminating the potential for adhesive failure and enhancing the flammability and smoke characteristics.
