However if you go for a quality engineered wood flooring you can even gone as far as to boil a piece of our floor for 30 minutes and the board still will not de-laminate. The 15mm ply wood under core is what gives the flooring the strength and stability is has. Oak is a natural product and when used for flooring the board widths can change in size. This can cause gaps between boards or the floor to buckle and this movement is most commonly caused by the changing of humidity in the environment. Because of the stability of a quality engineered oak floor it is far less prone to this movement. This stability is also becoming of greater importance today due to the fact that an increasing number of properties are having under floor heating systems installed, which of course causes a frequent change in humidity. Having said this I would again like to reiterate that I am writing in regards to a quality, higher spec engineered oak flooring, and I can not talk for all engineered wood floors.
In the case of long span truss work, bearing lengths of at least 3" are quite common. Trusses span greater distances than framed floor assemblies and can be designed to span the entire building, eliminating center load bearing supports. They are moderately more expensive than framed floor assemblies, but provide a remarkably strong floor with little deflection or "bounce" to it. Another advantage to this type of structural system, is that utility installations can be run between the webwork components. Never allow trades to cut or drill into the members of a truss, for they are manufactured precisely for the loading conditions they will undergo during the life of the building.
Truss floors are simply that. They are constructed from small dimensioned lumber, interconnected in a webwork pattern by the use of metal or wood plates. Occasionally, the trusses will be built on site, utilizing plywood plates to connect the webwork together. Generally they are installed 24" apart, either suspended on bearing walls or beams, or installed with plywood trim or rim joists around the perimeter. Strapping is installed on the bottom side, to prevent turning in place, which is a common ailment for deep truss components.
So let`s start off this article with talking about the number 1 reason our engineered oak floors have the upper hand over solid oak floors, this being it`s stability. A quality engineered board will be made up of around 10 layers of multi laminated birch ply wood. These layers are stuck in opposite directions with a moisture resistant adhesive and this gives the floor an immense amount of stability. We have been asked before by customers who have researched the market how strong the adhesive is as they have heard of stories of engineered wood flooring de-laminating.
