Around 150 dark red wood floorboards. Seem to have a laminate layer on top but made of very solid wood under that. Almost all of the boards had to be snapped when pulling them up and they are very scratched on the laminate side, so probably not good to use as flooring again in their current state. They are pretty heavy.
The full sized ones are 900mmx95mm and 20mm thick. There are a number of shorter peices too.
