The Kahrs Woodloc® wood floor joint system is an excellent quality system by Kahrs. "Woodloc is the the world's best mechanical wood floor joint" is the description by Kahrs the manufacturer. Woodloc® does not just mean that the floor can be installed quickly and efficiently. It also guarantees that the floor stays flat and that gaps will never appear between the planks. The fact is that the Woodloc® joint retains its strength throughout the floor's lifetime. So a floor from Kährs is also ideal with underfloor heating.
Woodloc is not actually flooring, it's simply the unique glueless joining system that Kahrs introduced in 2000.
