19 Oct Engineered Wood Flooring vs. Solid Wood Flooring
In 1941, Kährs is awarded a patent for the invention of today’s modern engineered hardwood floor, the multi-layer floor.
Before that wood floors were essentially solid, a homogeneous product from top to bottom and side to side.
Thickness, from around 14mm to 20mm or over, solid floors were simply wood planks/boards that were normally nailed to wood joists. 20mm of solid wood may seem the real deal but already in the 40s producers were aware that solid wood planks were unstable while multi layers were much more stable.
Quickly the concept of multi layer or engineered flooring took hold of the market and nowadays the very vast majority of floors are engineered.
Some 2 layers offers goo stability too but for extra wide and extra long floors up to 15,000mm 3 layers is a must.
