Wood: an ideal material for flooring
Wood is a wonderfully useful and versatile material.
For instance, wood has very good thermal properties.
In older buildings, solid wood was even used to provide insulation.
Wood is anisotropic -
It has different properties in different directions, e.g. when it absorbs or loses moisture.
A solid wood floor
Unlike the brick, drywall, or roofing on your home, the wood flooring installed on your floor is breathing. Yes, it is alive! The very product that creates the warm homey feeling that you walk across every day, which should last the life of your home, is constantly in change.

Copyright © 2009 Acorn Floor Sanding. All Rights Reserved.
Floor sanding is a method of sanding the floor surfaces made of woods.
The floors are subjected to sanding by different abrasive materials.
We offer the perfect process that requires highly professional floor sanding contractor to take care of your floor.
Wood is also heterogeneous -
Which means that different parts of it have different properties.
Hardwood is not the same thing as softwood, and wood from branches
is not the same as wood from the trunk.
Wood is hygroscopic -
It adjusts its moisture content to the relative humidity
of the ambient air.
Wood is also rheological -
Which means that it can change shape under a sustained load, and it can change colour over time.
Wood expands and contracts in all three dimensions.
The anisotropic and hygroscopic properties of wood are of the greatest importance when it comes to a wood floor.
The effect of UV daylight on a wood floor
Just as high sun exposure accelerates the wrinkling of human skin, causes fading of painted surfaces, and breaks down plastic, its direct rays can wreak havoc on interior floor finishes. Even indirect sunlight will cause fading and discoloration of finishes, and the damage is not limited to the finish system.
Even after floor finish is sanded off by commercial floor equipment, rug lines are still obvious, but more subtle.
Engineered wood flooring.
This type of floor starts with a bottom core (a "substrate" if you're fancy) of pressed plywood or manufactured wood layers, and is then topped with a nicer wood veneer; this top "wear layer" is the part that's seen once installed. The invisible bottom layers make natural movement easier, which prevents buckling or warping when temps fluctuate.
It also makes it more affordable. The top layer gives it the look and warmth of solid hardwood vs. the cheaper, plastic feel of laminate.
Even an old floor that is resanded will expose new wood fibres to the light which begins this colour change process.
The amount of change is dependent upon the amount of direct and indirect sunlight exposure the floor gets and the response of different species of wood is variable.
This colour change is the most dramatic in the first 6 months after it is sanded and finished.
It is recommended that rugs be moved periodically during this time to avoid leaving areas of uneven colour.
AVOID DIRECT SUNLIGHT
Depending on moisture in the air, wood fiber is either accepting moisture and growing in dimension, or dissipating moisture and shrinking.
This process is similar to a person inhaling and exhaling, except wood flooring is transferring moisture, not oxygen. In most parts of the country, wood flooring is inhaling (accepting moisture) in the spring and summer, and exhaling (dissipating moisture) in the autumn and winter.
As this occurs, dimensional change takes place potentially resulting in edge compression and swelling in the humid months, and shrinkage resulting in gaps between boards in the dry months.
