How to Determine the Thickness of Your Cork Underlayment How to Determine the Thickness of Your Cork Underlayment
Cork underlayment creates a sound proofing system for tile, wood and stone flooring options. The thickness of the cork will vary, depending on the flooring being installed. The typical thickness ranges between 1/8 and ½ of an inch. The thicker the cork underlayment, the more costly the material.
Step 1 – Determining the Flooring Choice
Before you decide on the thickness of the cork underlayment you are going to install, you need to choose the flooring that you want to lay on top of it. The type of flooring you lay will affect the thickness. Thicker and denser flooring options will require a thicker cork underlayment, for the best support.
Step 2 – Considering the Sound Resistance
Determine how much sound resistance you want to create in the room where you are installing the flooring. Cork underlayment with a thickness of 7/16 of an inch provides the maximum sound resistance. Cork any thicker than 7/16 of an inch will create no better sound resistance, but may void any warranty provided with the underlayment. Cork that is 1/2 of a inch in thickness, provides a satisfactory level of sound resistance. The thinnest cork available is ¼ of an inch. It provides a minimal amount of sound proofing in a room.
Step 3 – Considering Your Budget
Cork underlayment that is 7/16 of an inch thick is the most expensive choice. Cork underlayment that is 1/2 of an inch thick costs a great deal less, and still provides good sound proofing. The least expensive choice is the ¼ of inch underlayment. All of these options can range in price from about $1.50 to $5.00 a square foot.
