Armstrong Biome Stockholm (ST280) is the lightest color in the entire Biome collection and the only one rated at 60-64% light reflectance. It belongs to the Boreal design, which Armstrong describes as contemporary and clean, and its swatch appears soft off-white with fine, subtle grain.
Stockholm comes in 9"-wide planks, and the extra width changes how the floor reads. Each plank covers 3 sq. ft., half again as much as a 6" Biome plank, so a room needs two-thirds as many rows and shows fewer long joints.
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.
