Flooring should be split into sections at room doorways to help avoid expansion problems. In many cases the flooring will also meet another flooring type such as carpet at a doorway. In either case this leaves a join that needs to be covered.
Solid oak thresholds are a great way to cover this gap with a quality feel. Made from real oak by us, these thresholds are suitable for both 14mm and 20mm thick flooring, and are used where you are joining the flooring to another floor at the same level.
