6mm Cork Roll – 1/4" Premium Cork Roll | #1 Best-Selling Thickness

The 6mm cork roll — equivalent to 1/4 inch — is the bestselling cork roll thickness across the market, and BangorCork's most popular roll format. At this depth, the cork provides a firm, confident pin hold for all standard pushpins and thumbtacks, making it the default specification for high-quality bulletin board surfaces, school and office wall cork, and cork wall feature installations. Beyond pinboards, 6mm cork is widely specified as flooring underlayment for sound and thermal insulation — reducing impact noise beneath laminate, hardwood, and tile floors by a measurable degree. It also functions as a premium dart board backer, protecting walls from missed throws while providing a forgiving surface that self-heals between games. BangorCork's 6mm natural cork roll is sourced from certified Portuguese cork oak. Available in 4-foot widths and multiple lengths. If you are unsure which thickness to choose, 6mm is the industry-standard recommendation for most bulletin board and wall cork installations.
