Umber

Umber Cork Glue-Down Flooring

A Swiss-made 6 mm glue-down cork tile in a deep umber brown: AC5 abrasion rated, 18 dB quieter underfoot, and slim enough to run over hydronic in-floor heat.

Umber takes its name from its colour: a rich, earthy brown drawn from a natural cork veneer, finished in a high resistance matte coat that keeps the surface looking like cork rather than plastic. Square edges with no bevel and a straight cut let the 600 mm x 300 mm (23 5/8 in x 11-13/16 in) tiles lay up in a clean brick or stack pattern with tight seams.

The construction is cork through and through: a 0.7 mm to 0.8 mm natural cork veneer over a cork core and cork backing, sealed under a HotCoating wear layer. At just 6 mm (1/4 in) total, it glues direct to the subfloor, so there is no hollow sound and no height problem at doorways or transitions.

Stated impact sound reduction: 18 dB. Cork also provides cushioning and thermal insulation. Review the tested floor assembly and installation requirements.

Rated for domestic and commercial use, on grade and above grade, this tile is at home in kitchens, hallways, offices, and retail spaces, and it can be installed on walls as well as floors.

Important product note
