Armstrong Biome Oslo (ST281) shares a 50-54% light reflectance rating with Malmo, making them the second-lightest Boreal colors after Stockholm (60-64%). Oslo appears pale, cool gray-white with fine, straight grain in Armstrong's swatch, where Malmo leans cream.
Do the layout math for a 9" plank before cutting. Dry-lay from the room's center line to find the width of the last row, and don't let any border piece fall below 3". If the border would come in under half a plank's width, 4.5" for Oslo, shift the starting line by 4.5" to balance the room.
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.
