Bamboo has been used as an alternative for flooring because of its physical similarities to true hardwoods. Bamboo floor manufacturers and sellers promote its strength, durability, its eco-friendliness and its natural resistance to insects and moisture. The hardness of traditional bamboo flooring ranges from 1180 (carbonized horizontal) to around 1380 (natural), while newer manufacturing techniques including strand woven bamboo flooring range from 3000 to over 5000 using the Janka hardness test. Other flooring materials have comparable Janka ratings, with a higher number indicating a harder material: red oak (1290); white oak (1360); rock maple (1450); hickory (1820); and Brazilian Cherry / Jatoba (2350). [1]
Different forms of bamboo flooring exist. Each varies in its manufacturing process and differs largely based on economic viability and local preferences.
The most common form, particularly in southeast Asia, uses thin bamboo stems that are cut as flat as possible. They are cut to similar lengths and can be stained, varnished, or simply used as is. They are then nailed down to wooden beams or bigger pieces of bamboo stems. This form results in more space between each bamboo stem; flatness and tightness is not emphasized. This technique is usually used on stilted houses, resulting in better air circulation especially during the warmer summer months.
The manufactured bamboo flooring commonly found in North American markets is very highly processed. A Bamboo flooring is typically made by slicing mature bamboo poles or culms into strips. These culms are crosscut to length and then sliced into strips depending on the width desired. The outer skin and nodes are removed. [2] To remove starch and sugars the strips of bamboo are boiled in a solution of boric acid or lime. The bamboo is then dried and planed. Natural bamboo color is similar to beech wood. If a darker color similar to oak is desired, the bamboo goes through a carbonizing process of steaming under controlled pressure and heat. The carbonizing process can reduce the floor's final hardness significantly compared to non-carbonized bamboo, rendering it softer than some pines and softer than more common red oak.
Most bamboo flooring uses a urea-formaldehyde (UF) adhesive in the lamination process. Though the use of UF resins, which emit volatile organic compounds (VOCs), is harmful to indoor air quality, bamboo flooring uses a relatively small amount compared with other materials, such as particleboards. Bamboo flooring products that avoid formaldehyde use are available, including some listed in the GreenSpec Directory. [3] The panels are then heat pressed to cure the adhesive. The cured boards are then planed, sanded, and milled. Finally an ultraviolet curing lacquer is applied to the boards. [2]
Manufactured bamboo floors are typically made available in planks with either vertical- or horizontal-grain orientation. In vertical bamboo floors, the component pieces are stood vertically on their narrowest edge and then press laminated side to side. The effect is a lined, almost uniform look to the surface of the finished floor plank. In horizontal bamboo floors, the slats are arranged in a horizontal direction, on their widest edge, and then joined side by side with adjacent pieces using a high-pressure laminate system. The characteristic nodes of the bamboo are visible on the finished horizontal surface.
Locking bamboo flooring is the easiest to install. Individual flooring planks have interlocking joints that click precisely into place. By combining plank alignment and color a lot of different styles can be produced.[ citation needed ]
Strand woven bamboo flooring can be refinished with a clear-coat quite easily, however applying a stain on-site can be challenging.
Bamboo is an eco-friendly, highly renewable source of material. As a grass, bamboo grows much faster than wood. Moso Bamboo is the primary species used for the manufacturing of flooring and plywood. [4] Moso bamboo can grow up to 119 centimetres (47 in) in 24 hours and 24 metres (79 ft) high in 40 to 50 days. It takes about 3–5 years for bamboo to reach full maturity. [5] Traditional hard woods can take 20–120 years to mature. [6]
Bamboo can be harvested without the need to replant because the root system is left intact when it is harvested. The rhizome root structure has the ability to hold the soil in place preventing erosion. [4] Rhizome root structures are horizontal stems that grow below the surface and help a plant reproduce vegetatively. Plants with rhizomes will colonize or spread laterally. [7] In the United States of America, The Lacey Act recently strengthened the accountability in the sourcing of timber products. However enforcement is still in question. [4] [ relevant? ]
Bamboo reaches maturity in five years which is the optimal age to harvest. [4] In a sustainably harvested forest only 20% of the forest is harvested annually allowing for 100% harvest in a five-year period. In its natural environment it will need no irrigation, no pesticides, and no fertilizer. Bamboo has few pests so pesticides are not required. Bamboo certified to the standards of the Forest Stewardship Council (FSC) meets criteria for environmental sustainability and social responsibility, and several flooring products are available with this option. [3] Bamboo can sequester up to 70% more carbon per year than a hardwood forest. [4] All these factors keep the carbon footprint low.
The United States Green Building Council's LEED program allows points for the use of bamboo floors by virtue of it being a rapidly renewable resource.
Since the majority of bamboo timber comes from China, it has to be shipped to the international destinations by boat and then by truck to vendors. A study which compared the embodied energy (including transportation) of bamboo flooring from Hunan Province, China to Denver, Colorado favored locally sourced concrete above bamboo flooring due to the additional carbon costs associated with transport. [8]
Controversy exists over agricultural and manufacturing issues related to the production of bamboo floors, including the environmental effects of deforestation in order to plant bamboo [9] and the use of carcinogenic chemicals such as urea-formaldehyde in the glues used for lamination in some products. [10]
Bamboo flooring has led to deforestation, as existing trees are cut down to be replaced with bamboo plantations; this results in soil erosion in the often hilly and mountainous areas occupied by forestland, along with a loss of biodiversity in the region as other flora and fauna are cleared for bamboo. Additionally, the use of pesticides, weed killers and fertilizers in bamboo production can have an effect on the environment. [9]
During the manufacturing of bamboo floors, some manufacturers use urea-formaldehyde as the adhesive for bonding the bamboo strips. According to the stringent California Air Resources Board (CARB) standards there can be no more than 0.05 ppm (parts per million) of outgassed formaldehyde. [11] According to the USGBC's LEED standard products with Urea-formaldehyde do not qualify for the EQ 4.4 Low-Emitting Products category. [12] Manufacturers are now offering formaldehyde-free bamboo flooring, but they can claim that they have "no added urea-formaldehyde" without providing substantial proof. Manufacturers may make use of equipment that may in itself be dangerous and polluting. Some manufacturers may require their products to be registered under International Organization for Standardization (ISO) standards 9001 for quality control and 14001 for environmental management systems EMS, although these standards are not necessarily very high. [3]
Like most hardwood floors, bamboo floors should be treated carefully. When mopping, it is best to use a dust mop to remove the dust and grime. A stiff bristled broom can be used to remove more stubborn dirt from the crevices of the floor. Wet mops should be avoided on the bamboo flooring. When it is necessary to mop the floor, wring the mop out thoroughly to prevent any extra water from being released onto the floor. Cleaning detergents should be checked to make sure that they are safe for hard wood floors before they are added to the mop water. Many detergents contain a waxing agent which will dull the color of the flooring and leave behind a filmy glaze.
Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that are glued together with adjacent layers, having their wood grain rotated up to 90° to one another. It is an engineered wood from the family of manufactured boards, which include medium-density fibreboard (MDF), oriented strand board (OSB), and particle board.
Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. Floor covering is a term to generically describe any finish material applied over a floor structure to provide a walking surface. Both terms are used interchangeably but floor covering refers more to loose-laid materials.
Engineered wood, also called mass timber, composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite material. The panels vary in size but can range upwards of 64 by 8 feet and in the case of cross-laminated timber (CLT) can be of any thickness from a few inches to 16 inches (410 mm) or more. These products are engineered to precise design specifications, which are tested to meet national or international standards and provide uniformity and predictability in their structural performance. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products. The products can be used for joists and beams that replace steel in many building projects. The term mass timber describes a group of building materials that can replace concrete assemblies.
Oriented strand board (OSB) is a type of engineered wood similar to particle board, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. It was invented by Armin Elmendorf in California in 1963. OSB may have a rough and variegated surface with the individual strips of around 2.5 cm × 15 cm, lying unevenly across each other, and is produced in a variety of types and thicknesses. Though it may seem intuitive to assume that the term "chipboard" refers to oriented strand board based on its appearance, and to contrast it against particle board, the two terms are treated as synonyms by the industry, with the "chips" in chipboard being of a size that a lay person would readily judge to be "particles".
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibres but can be used as a building material similar in application to plywood. It is stronger and denser than particle board.
In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst. Heat is not necessarily applied externally, and is often generated by the reaction of the resin with a curing agent. Curing results in chemical reactions that create extensive cross-linking between polymer chains to produce an infusible and insoluble polymer network.
Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis. In North America, the material providing the laminations is termed laminating stock or lamstock.
Particle board, also known as particleboard, chipboard, or low-density fiberboard, is an engineered wood product manufactured from wood chips and a synthetic resin or other suitable binder, which is pressed and extruded. Particle board is often confused with oriented strand board, a different type of fiberboard that uses machined wood flakes and offers more strength.
Laminate flooring is a multi-layer synthetic flooring product fused together with a lamination process. Laminate flooring simulates wood with a photographic applique layer under a clear protective layer. The inner core layer is usually composed of melamine resin and fiber board materials. There is a European Standard No. EN 13329:2000 specifying laminate floor covering requirements and testing methods.
Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. It is typically used for headers, beams, rimboard, and edge-forming material. LVL offers several advantages over typical milled lumber: Made in a factory under controlled specifications, it is stronger, straighter, and more uniform. Due to its composite nature, it is much less likely than conventional lumber to warp, twist, bow, or shrink. LVL is a type of structural composite lumber, comparable to glued laminated timber (glulam) but with a higher allowable stress.
Urea-formaldehyde (UF), also known as urea-methanal, so named for its common synthesis pathway and overall structure, is a nontransparent thermosetting resin or polymer. It is produced from urea and formaldehyde. These resins are used in adhesives, plywood, particle board, medium-density fibreboard (MDF), and molded objects. In agriculture, urea-formaldehyde compounds are one of the most commonly used types of slow-release fertilizer.
A countertop, also counter top, counter, benchtop, worktop or kitchen bench, bunker is a raised, firm, flat, and horizontal surface. They are built for work in kitchens or other food preparation areas, bathrooms or lavatories, and workrooms in general. The surface is frequently installed upon and supported by cabinets, positioned at an ergonomic height for the user and the particular task for which it is designed. A countertop may be constructed of various materials with different attributes of functionality, durability and aesthetics, and may have built-in appliances, or accessory items relative to the intended application.
Fiberboard or fibreboard is a type of engineered wood product that is made out of wood fibers. Types of fiberboard include particle board or low-density fiberboard (LDF), medium-density fiberboard (MDF), and hardboard.
Columbia Forest Products is the largest manufacturer of hardwood veneer and hardwood plywood in the United States. Founded in 1957, it is headquartered in Greensboro, North Carolina. It specializes in decorative, interior veneers and plywood panels that are used in high-end cabinetry, fine furniture, architectural millwork and commercial fixtures. The company distributes its products primarily through a network of wholesale distributors, mass merchandisers and OEMs. Since 1976, the company has been completely employee-owned and currently has 10 manufacturing facilities throughout the U.S. and Canada. At the end of 2006, Columbia converted all of its standard hardwood plywood production to produce formaldehyde-free panels called PureBond. In 2007 Columbia added PureBond formaldehyde-free particleboard to its product range.
Building insulation materials are the building materials that form the thermal envelope of a building or otherwise reduce heat transfer.
Wood flooring is any product manufactured from timber that is designed for use as flooring, either structural or aesthetic. Wood is a common choice as a flooring material and can come in various styles, colors, cuts, and species. Bamboo flooring is often considered a form of wood flooring, although it is made from bamboo rather than timber.
OMNOVA Solutions Inc., is a global manufacturer of laminates, performance films and coated fabrics. OMNOVA was founded in 1999 when GenCorp spun off its Decorative & Building Products and Performance Chemicals businesses into a separate, publicly traded company. OMNOVA's world headquarters is located in Beachwood, Ohio with additional sales, manufacturing and distribution locations throughout Europe and Asia.
Sustainable flooring is produced from sustainable materials that reduces demands on ecosystems during its life-cycle. This includes harvest, production, use and disposal. It is thought that sustainable flooring creates safer and healthier buildings and guarantees a future for traditional producers of renewable resources that many communities depend on. Several initiatives have led the charge to bring awareness of sustainable flooring as well as healthy buildings. Below are examples of available, though sometimes less well-known, eco-friendly flooring options. The Asthma and Allergy Foundation of America recommends those with allergies to dust or other particulates choose flooring with smooth surfaces – such as hardwood, vinyl, linoleum tile or slate.
Plyboo is one of the brands owned by Smith&Fong Co., a privately held building materials company based in San Francisco. Plyboo was launched as a brand in 1993 by Smith&Fong, the first U.S. company to sell imported bamboo flooring in North America. Although Smith&Fong Co. is the parent company, Plyboo has come to be how the company is primarily identified.
LL Flooring is an American retailer of hard-surface flooring including hardwood flooring, laminate flooring, vinyl plank flooring, tile flooring, bamboo flooring and cork flooring, as well as flooring tools and accessories.
