Durable finish of Treffer or Klump coating applied during the manufacturing process. Unique, elegant and distinguished flooring. Hardness. Moisture Resistance, Fire Resistance and Insect Resistance
Bamboo is an environmentally friendly, renewable resource that has been used as construction material for thousands of years. Ecologically, the harvesting of bamboo does not affect the world’s already dwindling timber resources. Technically considered a grass, bamboo has the ability to grow to maturity in 4-6 years. The intricate root system remains unharmed upon harvesting and allows for sustainable future growth. Using bamboo is a natural alternative to traditional hardwood flooring while at the same time doing something good for the environment.
Bamboo flooring has greater dimensional stability and therefore less expansion and contraction than traditional wood floors. Adding to its natural strength is a lamination process that prevents expansion and contraction. The end result is a beautiful floor to enjoy for a lifetime.
Three Layers aluminum oxide finish applied during the manufacturing process makes pre- finished bamboo flooring more durable, resistant to indentation and abrasion when compared to a traditional hardwood flooring finishes.
Bamboo is a grass rather than a tree and so its finished appearance is very distinctive. Most distinctive is slightly darker bands produced by its nodes. Bamboo’s other aesthetic features includes the tightness of its grain and the uniformity of its color. Generally bamboo is available in its light, natural color or in darker shades produced by carbonization. Carbonization is a manufacturing process that subjects the bamboo to steam and pressure. This causes a darkening of the sugar content in its fibers resulting in a honey-brown color. The shade of the color is dependent upon the length of the process. Appearance of the finished product is further enhanced by the various plank constructions. Choices include vertical or horizontal solid construction, engineered construction, and woven stranded construction. The MOSO specie of Bamboo is harvested at maturity in 4 to 6 years to ensure hardness, stability and clarity of color.
Solid Bamboo has an average hardness of 1820 ( Janka Ball test) which makes Yunsheng bamboo flooring harder than white oak (1360) and rock maple (1450).
Bamboo grows in tropical regions so is naturally moisture resistive. Also resistive to spills and stains. Suitable for areas like bathrooms and kitchens.

Zebrano is made of bamboo fibers that are laminated together with a low-formaldehyde adhesive. The processing methods employed in this revolutionary product contribute to its rigidity, two times harder than any traditional bamboo floor. Its incredible hard, durability, and moisture-resistance make it an ideal choice for high-traffic residential and commercial applications. Zebrano bamboo flooring - ranks among the hardest species of hardwood flooring due to a unique patented manufacturing process using bamboo fibers fused together with an environmentally safe adhesive put under extreme pressure of nearly 2500 tons. Twice as hard as Red Oak. Perfect for commercial as well as high traffic residential installations.
May be nailed/stapled or glued down on or above grade; ideal over radiant heat systems.

Solid Bamboo has an average hardness of 1820 (Janka ball test) which makes bamboo flooring harder than White Oak (1360) and Rock Maple (1450); A durable, 7-coat Treffert coatings low-gloss finish system provides the wear protection of aluminum oxide with two polyurethane scratch-resistant topcoats. Coating is water- based and solvent-free and meets U.S. and stringent European (E1) standards for off-gassing. Available refinished with micro-bevel edge or site-finished with square edge. The Dynea adhesive used to bind the bamboo slats together to form a flooring plank has virtually no formaldehyde - 48 times lower than OSHA standards allow and 6.5 times lower than allowed by the more stringent European (E1) standards.
Phyllostachys pubescens, generally referred to in the international technical literature is a temperate zone bamboo ( Grown in P.R. China at a latitude approximately the same as northern Florida).
In a related phenomenon, strips cut from bamboo, like strips or planks cut from any tree, naturally want to bend or curl in a predictable direction. These bending or flex forces are very powerful, as designers of plywood products know well. Therefore, it is critical that the forces associated with these natural flex tendencies be directionally balanced within each bamboo flooring board
The Calypso bamboo stalk, or culm, is harder on the outside than on the inside. A higher concentration of vascular bundles, or capillaries, along with the associated silicate deposits, on the outside of the culm gives rise to this phenomenon. As a consequence, each strip cut from the culm and used in flooring is harder on one side than on the other. The hard side often is quite visually apparent by looking at an end cut of a strip and noting the much higher concentration of the "dots" or capillaries on the hard side.
All bamboo flooring manufacturers use urea formaldehyde resin in their laminating adhesives. This is the same adhesive used in all conventional interior-plywood products as well. “Adhesive Formulation” ASTM E is an industry accepted standard for measuring formaldehyde out gassing levels in urea formaldehyde based adhesives. The standard set by the U.S. Department of Housing and Urban Development (HUD) is.3 ppm of formaldehyde. Calypso adhesives test at.04 ppm or about eight times better than the HUD standard.
The Calypso pre finished flooring has five coats of a polyurethane acrylic based system. The total coating applied is grams per square meter. Where specified, aluminum oxide “ceramic” inclusions are included in the second layer applied. Each layer in the system is UV cured. The Calypso pre-finished flooring has been tested pursuant to ASTM C 1028 which is an industry-endorsed protocol for measuring the static coefficient friction of the surface under wet and dry conditions. Average Coefficient of Friction results were.731 (dry) and.925 (wet).
When we think of a solid wood floor we generally think of the standard strip oak wood floor that is 3/4" thick by 2 1/4" wide shown above, but solid wood floors are also available in various sizes from 3 to 6 or more inches wide (called plank floors). Custom Milled sizes less than 2-1/4 or wider than 6 inches wide are also available and are available in different thicknesses. The floorboards are generally in random lengths from 12" – 84"; Custom Milled lengths can exceed 12’ long. The most common wood species used for solid wood floors are red oak, white oak, and maple, although they are available in many other wood species.
All solid wood floors can react to the presence of moisture. In the dry winter heating months, moisture can leave the wood causing the floor to contract slightly in size, which can leave unsightly gaps between each board. In the summer months when the humidity is higher the wood will expand and the gaps will disappear. If there is too much moisture it may cause the wood planks to cup, or buckle. This is why it is important when installing a solid strip floor to leave the proper expansion area around the perimeter and to acclimate the wood prior to installation. It is also important to keep the relative humidity at between 40 – 55%. Doing this will help minimize any movement within the floor. Solid wood floors are sensitive to moisture and it is not recommended to install these floors below ground level, or directly over a concrete slab. Solid wood floors are for nail-down installations only; you can refinish, or recoat solid wood floors several times, which adds to their appeal and to their long life. There are solid floors that are well over 100 years old and are still in good condition.
What is the advantage of using a Solid wood floor over the other types such as an engineered floating or glue down floors? A. 3/4 Solid wood flooring has a thick 5/16 top wear layer that can be sanded and refinished new again up to 7 times and can last well over 100 years. Solid hardwood flooring also adds structural strength to a floor system due to its 3/4 thickness and interlocking Tongue and Groove milling. If you have a wood sub floor you would most likely want to use a 3/4 solid wood floor. Solid wood flooring is cut out from a solid piece of wood.
Why beveled edges at all? After the milling process of the hardwood there is a possibility of minute differences to the exact thicknesses of each floorboard. Different manufactures have different milling tolerances some are more stringent than others. A beveled edge board (to whatever degree) eliminates the possibility of feeling a sharper edge that is sometimes found on square edged prefinished flooring. Slight indifference may also be felt if square edged prefinished flooring is installed over an uneven sub floor.
Is the bevel object able? The smaller "Micron or Micro" bevel is virtually unnoticeable, as even with any square edged flooring you will see a seam between boards. Also, these Micron or Micro beveled edges are far too small to collect dust or dirt.
The edges of all boards meet squarely creating a uniform, smooth surface that blends the floor together from board to board. The overall look of this floor gives a contemporary flair and formal feeling to the room. Micron-beveled edge has the shallowest groove. Micron- bevel and micro-bevel are so close that between manufacturers they may be hard to determine any difference. Micro-beveled planks have a slightly shallower groove than most eased edged planks. Like the eased edge, the micro- bevel is meant to help hide minor irregularities, such as uneven plank heights.
The eased edge has a slightly shallower groove than the full beveled edge. Some manufacturers add the eased edge along both the length of each planks as well as along the end joints, this will give the floor a different visual effect when installed. These products have a very distinctive deep groove in them. Beveled edge planks lend themselves to an informal and country decor. With the urethane finishes applied at the factory today the beveled edges are sealed completely making dirt and grit easy to be swept or vacuumed out of the grooves.
