CORK: An Environmentally A Green Product

Cork is produced, rather actually 'farmed' from trees. The bark is peeled without damaging the tree. TLC is given to all our tress so they will bear fruit in the future.

Other Factors Affect Sound Abatement
Flooring contractors are required to meet the city’s or home owner’s association requirements for sound abatement. AcoustiCORK™'s cork underlayment will meet HOA and the city’s specifications. Please view Sound Transmission Class (STC) and Impact Insulation Class (IIC) reports below. These reports are performed by Riverbank Acoustical Laboratories of Geneva, IL. Don’t ask for generic cork underlayment, demand AcoustiCORK™ To determine the appropriate product, please visit our Cork Underlay Product Guide.

There are other factors that influence sound level transmission other than the composition of the floor, whether concrete, wood or other. For more significant sound abatement cork underlayment planks or cork rolls can be applied behind all types of dry walls and above or even on ceilings made of drywall (Plaster or lathe). STC Test Results For Cork Underlayment

Walls between condominiums units and offices are only a true a boundary when noise is contained within your unit. The point is; cork underlayment constructed behind dry walls will add a sound barrier between condo units, offices and even cubicles using solid cork underlayment or cork-rubber blend underlay.
