Choosing the best flooring for your dream home is not an easy task. There are a wide variety of flooring options available in the market, and it is sometimes frustrating to select the right type of flooring. Engineered wood flooring is a cost-effective and eco-friendly flooring option to add a touch of elegance to your new home. Read more about the unique features of engineered wood flooring below:

1. Engineered wood is eco-friendly

With increasing focus on green lifestyle, homeowners are looking for eco-friendly hard flooring to make their homes truly green and environmentally-friendly. The appearance of engineered wood flooring is almost the same as that of solid wood flooring but the manufacturing processes are quite different.

Engineered wood flooring is made up of a thin veneer on top of a less-expensive plywood. This distinctive style of manufacturing not only helps in conservation of natural wood, but also makes the flooring both cheaper and stronger. A new industry trend is to replace plywood with recycled wood fiber mixed with stone dust which provides additional dimensional stability.

2. Ease in installation

Engineered wood flooring offers installation advantage as it is easier and cost-effective to install than traditional hardwood floors. The wide range of engineered wood floor installation methods include stapling or nailing, fold-and-lock, or glue. The ease in installation makes it ideal for both DIY and professional installation.

Engineered wood floors are milled with tongue and groove (T&G) construction in which the planks are fitted together, like puzzle pieces, with each row held down by the row next to it. Tongue and groove milling allow the floors to be stapled or nailed down, glued, and sometimes floated. The versatility of engineered wood can be gauged from the fact that it can be directly installed over a concrete subfloor or on top of old hardwood floors.

3. Better resistance to moisture

Engineered wood is more capable of fighting moisture than conventional wood floors, primarily due to its dimensional stability which prevents warps and other deformities when it comes into contact with water. The relatively stable structure of engineered wood is provided by the cross-wise layers of plywood fibers which is in contrast to parallel fibers of hardwood.

The moisture-resistant nature of engineered floors makes it well-suited for moisture-prone areas like bathrooms and basements. The ability to withstand moisture means engineered wood is more durable than conventional hardwood floors.

4. More resistant to temperature changes

Compared to traditional hardwood floors, engineered wood floors have better capabilities to resist temperature changes. The multiple-ply plank design facilitates its expansion without compromising on its structural strength and stability.

The hardwood and plywood layers are bonded together under heat and pressure which negates the natural tendency of hardwoods to expand, contract, warp, or cup when exposed to temperature changes in certain areas, like utility rooms.

5. Amazing range of styles, grades and finishes

Engineered wood floors can adapt to your lifestyle as well as your budget. It is available in a wide array of styles, like oak and maple, and diverse range of multiple finishes including matte, semi-gloss, and high-gloss. You have the option to go for cost-efficient tough, lacquered floor or to choose the top-quality oiled version. You also have the liberty to choose a rustic or a time worn appearance, depending on your preferences.

Conclusion

Engineered wood floors is a cost-efficient, durable, versatile and eco-friendly alternative to traditional flooring options, like hardwood, laminate and parquet flooring. Its ability to withstand moisture and temperature changes makes it well-suited for all kinds of residential and commercial buildings.

The easy installation and hassle-free maintenance of engineered wood flooring makes it attractive for an amateur DIY buff as well as for a professional interior decorator. To sum up, engineered wood floors are a logical and green alternative to provide elegance and creativity to your new home.

Biomass from Wood Processing Industries

Wood processing industries primarily include sawmilling, plywood, wood panel, furniture, building component, flooring, particle board, moulding, jointing and craft industries. Biomass from wood processing industries is generally concentrated at the processing factories, e.g. plywood mills and sawmills. The amount of waste generated from wood processing industries varies from one type industry to another depending on the form of raw material and finished product.

Saw-dust

Biomass from Wood Processing

The waste resulted from a wood processing is influenced by the diameter of logs being processed, type of saw, specification of product required and skill of workers. Generally, the waste from wood industries such as saw millings and plywood, veneer and others are sawdust, off-cuts, trims and shavings. Sometimes, it becomes a complex task to select the best scroll saws for wood cutting.

Sawdust arise from cutting, sizing, re-sawing, edging, while trims and shaving are the consequence of trimming and smoothing of wood. In general, processing of 1,000 kilos of wood in the furniture industries will lead to wood waste generation of almost half (45 %), i.e. 450 kilos of wood. Similarly, when processing 1,000 kilos of wood in sawmill, the waste will amount to more than half (52 %), i.e. 520 kilo of wood.

The biomass wastes generated from wood processing industries include sawdust, off-cuts and bark. Recycling of wood wastes is not done by all wood industries, particularly small to medium scale wood industries. The off-cuts and cutting are sold or being used as fuel for wood drying process. Bark and sawdust are usually burned.

Recycling of Wood Wastes

The use of wood wastes is usually practised in large and modern establishment; however, it is commonly only used to generate steam for process drying. The mechanical energy demand such as for cutting, sawing, shaving and pressing is mostly provided by diesel generating set and/or electricity grid. The electricity demand for such an industry is substantially high.

Recycling of wood wastes is not done by all wood industries, particularly by smallholders. These wastes are normally used as fuel for brick making and partly also for cooking. At medium or large establishments some of the wastes, like: dry sawdust and chips, are being used as fuel for wood drying process. Bark and waste sawdust are simply burned or dumped.

Importance of Heating Value

The heating or calorific value is a key factor when evaluating the applicability of a combustible material as a fuel. The heating value of wood and wood waste depends on the species, parts of the tree that are being used (core, bark, stem, wood, branch wood, etc.) and the moisture content of the wood. The upper limit of the heating or calorific value of 100% dry wood on a weight basis is relatively constant, around 20 MJ/kg.

In practice, the moisture content of wood during logging is about 50%. Depending on transportation and storing methods and conditions it may rise to 65% or fall to some 30% at the mill site. The moisture content of the wood waste in an industry depends on the stage where the waste is extracted and whether wood has been dried before this stage.
