Why are TEKA products better than others?

1. Raw Material

While most manufacturers compromise on raw material by sourcing cheaper White Oak from Russia or America with less grain character, TEKA sources its German and French White Oak from their own subsidiary located in Germany. Our control and involvement in picking each tree ensures that we are getting the best quality and character of raw material.

2. Platform and Construction

Most manufactures also cut costs by using plywood as a core and as a backer substrate to carry the face layer. We use a superior solid hardwood lumber construction.

Plywood by itself is a stable product. It is made up of many thin plys of wood cross glued in the opposite direction of the grain. The idea behind it is to create a wood which expands in the width as much as in the length, but all other woods expand in the width 10 times as much as in the length.

By using a stable product, plywood, and adding a face layer of wood which wants to expands 10 times as much in width as in the length you are creating an unstable product again.

Using our solid hardwood lumber core glued into the opposite direction of the face layer, and adding a solid sawn back, again in opposite grain direction, we are limiting the shrinking and expanding of your floor to a minimum.

You might not see a difference when you compare individual pieces of these two construction types, but when your floor is installed and there is a change in humidity, you will see less movement with our solid hardwood lumber core and back.

3. Sawn Face Layer vs. Sliced Face Layer

While most manufactures use sliced face layers, we are using sawn face layers. Why do we do this if they both look the same and sawn cut is more expensive?

 

When you slice wood, you basically use a knife which you press with high pressure through wood in order to get a face layer. This method is much more cost efficient because it's faster. The slicing method also eliminates the loss of material through saw dust that a normal saw blade would produce. Sounds like a good idea, but there is a catch to it; pressing a knife with that amount of pressure through hardwood creates an enormous amount of stress in the wood resulting in various small cracks along the side of which the knife entered.

The microscopic picture to the left shows two pieces of sawn cut wood glued together. The smooth surface provides excellent bonding strength between the face layer and core material providing lower risk of de-lamination, or adhesion failures.

 

The microscopic picture to the left shows two pieces of sliced veneers glued together.The cracked and uneven surface provides less strong bonding strength between face layer and core material more likely causing de-lamination.

 

4. CARBONIZING / FUMING

With our carbonizing / fuming treatments we have the benefit that the color is not a stain sitting on top, but our heat treatment changes the structure of the wood, making it dark brown (carbonized) or black (fumed) going through the entire face layer. In case you scratch your floor, no lighter color will come through

Although these technical differences may not be visible to the naked eye upon making your decision to purchase, they may have huge impact later on down the road. Wood is a natural product and is always fighting to go back to it's circular original form. It is important to know and understand the characteristics of wood and use the best methods and technologies available on the market to ensure you have a higher quality product.
