Umber Cork Glue-Down Flooring
A 1/4 inch (6 mm) Swiss-made cork tile in a deep umber tone, glued straight to your subfloor for a quiet, commercial-grade surface. Umber takes its name from the classic earth pigment, and the tile wears it well: a rich, shaded brown face of natural cork veneer, 0.028 to 0.031 inch (0.7 to 0.8 mm) thick, protected by a HotCoating wear layer with a high resistance matte finish. Each tile is a clean 23 5/8 x 11 3/4 inch (600 x 300 mm) rectangle with a square, straight-cut edge and no bevel, so the finished floor reads as one continuous surface rather than a grid. Because it is a glue-down tile, the whole 1/4 inch (6 mm) of cork bonds directly to the subfloor with Wakol D3540 adhesive, then gets sealed on site with two coats of Loba 2K polyurethane. The result is a permanent, water-resistant installation that recorded 0 percent swelling after 24 hours in water testing. Underfoot, this is cork doing what cork does best. The cell structure gives you a resilient, low-slip surface with a cushioned feel, cuts impact sound transmission by 18 dB, and holds warmth in the room (thermal resistance of 0.080 m2 K/W). It is rated for commercial class 31 duty as well as residential use, and it can go on walls as well as floors.This tile cannot be sanded or refinished. If the surface needs renewing, the factory finish can be lightly abraded and recoated with water-based polyurethane. Solara is the only solid cork floor tile we offer.
Why this floor
- 18 dB impact sound reduction (EN ISO 717-2): keeps footfall noise from traveling through the floor or the ceiling below.
- Commercial class 31 and domestic class 23 rated, with AC5 abrasion resistance and suitability for type W castor chairs.
- 0 percent swelling after 24 hours of water exposure (EN 317), with very good chemical resistance: a water-resistant floor once sealed with two coats of Loba 2K.
- Natural cork veneer top layer, 0.028 to 0.031 inch (0.7 to 0.8 mm), under a HotCoating wear layer with a high resistance matte finish.
- Thermal resistance of 0.080 m2 K/W keeps unwanted heat out in summer and holds warmth in winter, trimming heating and cooling bills.
- Low VOC emissions and made with formaldehyde free adhesives; cork contains suberin, a natural waxy substance.
- Cfl s1 reaction-to-fire rating and residual indentation of 0.25 mm maximum for a resilient floor that recovers from daily impacts.

Did the laundry room with these tiles, 260 sq ft, one afternoon with a roller. Rolled it properly and there’s no lifting at the edges. Holds up to work boots better than the vinyl it replaced.

Went down over sealed concrete in the cabin and it has held. Tiles are dense at 1/4 and cut clean with a straight edge. Six months in and it looks like week one.

Glued this down in the garden room with contact cement both sides. The Umber is neutral, not plasticky in daylight. Delivery split across two days, which slowed the job.
