engineered wood does not look exactly like real wood


Ech-Plank is based on Tech-Wood's trademarked Wood 2.0, a patented composite material technology, on which the company offers a 50-year guarantee. The fully recyclable composite consists of 75 percent long-strand pine-wood fibers and 25 percent virgin polypropylene. The company claims that its formulation is superior to traditional wood plastic composite profiles. waterproof decking
Offered in engineered shapes with a distinctive woodgrain look and high dimensional strength, the planks are free of preservatives and chemical biocides, yet the company says they are impervious to termites and carpenter bees. Unlike fiber cement siding, for which installers must use special cutting blades, Tech-Planks require no special tools or handling. Because of its high wood content, the composite can be cut, routed, drilled, nailed and/or sanded like natural wood and, reportedly, matches wood's mechanical properties as well.
Nothing will impact the appearance of your home more dramatically than the exterior siding you choose. As you shop for exterior siding, look for a siding material that suits the style of your house and also fits your lifestyle.

Modern science has given us many synthetic wood-look products, and yet solid wood (usually cedar, pine, spruce, redwood, cypress, or Douglas fir) remain favorite choices for finer homes. With periodic care, wood siding will outlast vinyl and other pretenders. As with cedar shingle siding, wood clapboards can be stained rather than painted. Many wood frame houses built centuries ago still look beautiful today.
Engineered wood, or composite wood, is made with wood products and other materials. Oriented strand board (OSB), hardboard, and veneered plywood are examples of engineered wood products. Engineered wood usually comes in panels that are easy and inexpensive to install. The panels may be molded to create the look of traditional clapboards. Because the textured grain is uniform, engineered wood does not look exactly like real wood. Still, the appearance is more natural than vinyl or aluminum. cheap exterior floor tile
The third way to comply is to pass the Office of the State Fire Marshal Standard SFM 12-7A-1 for Exterior Wall Siding and Sheathing. This is the method used for other combustible siding products (for example, untreated wood lap and panelized siding, vinyl or other plastic or wood-plastic composite product.) The SFM wall test evaluates the ability of the siding product (and assembly) to resist the penetration of a flame into the stud cavity. It doesn't consider vertical flame spread on the wall.
These photos are from a fire demonstration, and is intended to show these two factors. The photo on the right shows a corner section. The flaming wall was made with a composite siding product. The other wall (not burning) was made with a fiber cement siding product.
