About laminated wood

Laminated wood

Laminated wood has emerged from understanding the behavior of wood structure in the idea of providing stability to woodwn products, development of unique elements of carpentry but also as a modern trend in construction.

It has no applicability limits. Today we meet laminated wood everywhere in the everyday life. Furniture, machinery construction, musical instruments, building materials, medical instruments, sports equipment, etc., all use laminated wood as a material unmatched in properties, design and quality.

What is laminated wood?

Laminated wood

We know that wood is an organic matter, natural wood coming from the woody plant, being composed mostly of cellulose and lignin. Wood has a specific anatomical structure for each species of tree, so that they can be recognized depending on structural differences. Scientific description of wood structure and identification of tree species is what wood anatomy is about.

Production of laminated wood starts with cutting the logs into pieces of various sizes and thicknesses, depending on the type of laminated wood needed.

After drying it and bringing it to a relative humidity of 8-12% water content, follows the finishing of the parts that are going to form the laminated wood structure, watching to obtain smooth surfaces.

The elements thus obtained stick (stratify) between them, using various special adhesives for wood, by cold or hot pressing with special presses and maintaining it in this position for a period of time that will vary according to adhesive type, ambient and press temperature, essence, etc.

After removal from press, it can be subject to size adjustments, resulting the finished product in form of prime matter.

Laminated wood for windows and doors

Laminated wood profile

The goal is to eliminate the internal tensions within the wood fibers, tensions which often cause changes in wood structure, resulting in contortion, bending, loss of initial dimensions. These facts led to the idea that wood "works" in time.

Laminated wood elements used in the production of windows and doors, usually have three layers of wood in their composition, often stuck with water-based adhesives from D4 normative, resistant to moisture. It is considered that the three layers, working independently, cancel the internal tensions within the wood, providing stability to the prisms.

For laminated wood windows with insulating glass, the dimensions for the finished profile's section are 68 mm width and 78 mm height. For doors, 68 mm width and 110 mm height. These are standards used by most European countries.
