Engineered Hardwood Floors:

engineered hardwood floors

This is a type of flooring that is made up of several layers of veneered wood. Real hardwood is used for the top layer, and high-quality plywood or other materials are used for the lower layers. 

Engineered hardwood is less likely to expand and contract as a result of variations in humidity since it is more dimensionally stable than solid wood. It can be put in several ways, including floating, gluing down, or stapling down.

Scientific Knowledge About Wood

Cellular Structure:

Xylem cells, which are in charge of moving water and nutrients throughout the tree, make up the majority of the cells that make up wood’s cellular structure. The wood’s strength and stiffness come from the secondary cell wall, which contains lignin and is built up of cellulose in the primary cell wall.

Growth Rings: 

Growth rings, which are concentric circles with alternately spaced bright and dark bands, are visible when examining a tree trunk in cross-section. 

These rings are a representation of the annual growth cycle, with the lighter bands (earlywood) created during the spring’s rapid development and the darker bands (latewood) created during the summer’s slower growth.

Natural Resistance: 

Some types of wood are naturally resistant to rot, fungi, and insects. Examples include teak and Ipe, as well as cedar, redwood, and several tropical hardwoods.

Sustainability: 

When obtained ethically, wood is a renewable resource. Replanting trees to replace those that have been cut down is a component of sustainable forestry practices.

Natural Corrosion:

Given that it includes acetic acid (C2H4O2), wood is naturally corrosive. Wood is more instantly caustic when it is kiln-dried than when it is air-dried because kiln-drying hastens the generation of free acetic acid. 

Corrosion levels are higher in species with low ph. One of the most acidic and metal-corrosive wood species is oak, which has some of the lowest pH values. The main organic components of wood fiber are cellulose, hemicellulose, and lignin, but wood can also contain volatile alcohols, esters, and oils that can make an environment even more prone to corrosion when mixed with metal and corrosive chemicals (like floor finish).

The Hardwood Floors Are Made Of

As you are already aware of this formation, hardwood floors come from trees, and trees have knots. And these knots in wooden floors are not produced intentionally. But rather than they grow naturally in woods. 

These knots are made of the branches that grew from the trunk. Later on, these branches are cut off, and there left a hole and void in the wood. To fill these voids a harder and more durable material is used to fill them, known as a knot filler. 

The complete hardwood flooring involved cutting, and milling knots into planks or boards. To enhance the natural beauty of hardwood floors, knots are intentionally used. 

Wisely Use Of Knots:

The manufacturers use these knots wisely for hardwood floors. Typically highly graded floors have fewer knots. It is important to know the formation of knots in hardwood floors is natural.
