Wood's Expansion and Contraction

Expansion and contraction of wood is perfectly normal during changes in the weather. Wood is a natural material that seeks to be in balance with its
surroundings. Hardwoods destined for use in home furnishings are carefully kiln-dried for that purpose, and they will take on or give off moisture with
extreme changes in relative humidity. When the air is exceptionally warm and humid, solid hardwoods will absorb moisture and expand. Likewise, with
much cooler, drier air, the wood will give off moisture and contract. This is completely natural, and craftsman design fine solid hardwood products to
accommodate these changes.

Here are a few tips to help you be weather-wise:

Maintain relative humidity of at least 50 percent; i.e., use a humidifier in winter and an air conditioner in summer.

If you are planning a hardwood floor be sure to understand hardwoods' special features and how to deal with them.
Remember that hardwoods are natural materials and they will expand and contract with extreme changes in your home's relative humidity.
Hardwood flooring offers a wide variety of design
options. From standard plank types to hand cut intricate
patterns the clean, sharp look and feel of hardwood
evokes a sense of comfort, warmth and beauty.
Choice #1: Unfinished wood flooring:
Unfinished flooring is a product that must be job-site sanded
and finished after installation.

Choice #2: Pre-finished wood flooring:
Pre-finished flooring is factory sanded and finished flooring that
only needs installation.

Choice #3: Solid wood flooring:
Solid wood flooring is completely lumber. It is available in
unfinished and pre-finished.

Choice #4: Engineered wood flooring:
Engineered wood flooring is produced by bonding layers of
veneer and lumber with an adhesive. Engineered wood flooring
is available in pre-finished and unfinished. These products are
more dimensionally stable and are ideal for glue-down
installation or float-in installation above grade, on grade or
below grade, including basements and humid climates.  
Each hardwood offers its own distinct advantages. People are
often surprised by the limitless choices that wood flooring
affords them. Today's wood flooring is right for virtually every
room. Choosing the right kind and style of wood flooring is not
hard if you are familiar with several industry terms.
