Copenhagen (ST283) is a Boreal mid-tone at 25-29% light reflectance, between Gothenburg (30-34%) and Bergen (15-19%). Armstrong's swatch suggests a medium taupe-brown with fine, straight grain.
Armstrong describes Biome's designs as distinct yet compatible, and they share the same construction: every Biome plank, 6" or 9" wide, is 2.5 mm thick with a 20 mil wear layer and installs with the same approved adhesives. That lets you pair Copenhagen with a 6" Biome design in adjoining areas without a change in floor height.
Finish: Diamond 10 Technology
Installation and warranty: Full-spread glue-down. The 30-year commercial limited warranty requires a recommended Armstrong adhesive, such as S-995 or S-1000, installed according to Armstrong's instructions.
