Height differences
Different material thicknesses can create changes in level that need to be resolved in the floor assembly.
Traffic
Carts, wheelchairs, luggage and pallet equipment may repeatedly cross transitions.
Accessibility
In the U.S., ADA accessibility standards regulate floor and ground surfaces and changes in level on accessible routes.
Detail early
Transition details are easier to solve during design than after both floor systems are already selected.
Commercial flooring decisions depend on the actual substrate, moisture conditions, traffic, cleaning regime, accessibility requirements, fire/building rules, manufacturer instructions and local code. This site is for planning and comparison, not installation instructions.
