Outdoor Material Pros Cons: Wood Preservative vs WPC vs Bamboo

With the outdoor patio living requirements of continuous improvement, outdoor wood species also increases. From the preservative treatment of wood, to wood plastic composite, as well as high resistance outdoor bamboo decking entering into the market at the 2010 World Expo, bamboo decking which is bamboo strips in processing of gluing and pressing and oiling, are due to the different characteristics and become the natural beauty of outdoor living and create a good choice. Outdoor wood selection is rather special, outdoor wood commonly used are the following, we focus to give you a comparison:

Extensive use of wood preservative

Under the adverse external environment, ordinary wood cannot resist mold, rainwater erosion, highly perishable. By using of wood preservatives, you can prevent wood rot and wood decay function. It is in a vacuum state, the preservative agent through the high pressure timber was immersed tissue cells, fibrous tissue and cell tightly mixed and drug is not released. Preservatives are currently CCA / ACQ, CCA Ge main component is copper arsenic, ACQ main component of ammoniacal copper alkylamine. Because of its ordinary timber maintains the same characteristics, colors and textures, so in the outdoor environment it has a wide range of usage in the gardening.

Pros: In fact, in addition to wood preservative, but also has anti-termite, fungal, anti-corrosion of the three basic functions. Wood preservative and good permeability, resistance to the loss of strong features, while inhibition of treated wood moisture content change, reducing the extent of cracking wood.

Cons: Since immersed pharmaceutical during pressing process, wood will have slightly greenish chemicals and uneven color, big color variation and not shiny, with the loss of chemicals, color changes to gray, black. And generally wood preservative did not take secondary kiln drying and high moisture content of the wood itself, so it is easy to face deformation and cracking problems.

Application: outdoor and patio terrestrial platforms, guardrails, pavilions, pergolas, tables, chairs, small items.

Natural simplicity of carbonized wood (deep carbonization)

Carbonization wood is also known as charcoal wood, without any chemical agents in the application of high temperature conditions for homogeneity of wood carbonized available nutrients, decay fungi survive by cutting the nutritional chain to achieve the purpose of anti-corrosion.

With dark brown aesthetic effect on wood surface, carbonization wood has antiseptic and anti-biological attack role, and its low moisture content, low moisture absorption, material has high stability, no distortion, no excess fat totally defatted, good insulation, simple construction, no special smell , is the ideal sauna material, and its anti-rot, anti-moth, anti-deformation cracking, high temperature performance has also become an ideal material for outdoor pool landscape. It is a truly green building materials, green building materials.

Pros: Surface charring, corrosion resistant to microbial attack capability, which can be assimilated carbon layer on the surface of the paint timber and wood grain surface irregularities highlighted. Deep carbonization wood has the same color inside and outside, shiny as silk, clear texture, feeling warm. Good processing performance, overcoming the shortcomings of surface chips out. Low moisture absorption, low moisture content, it is not cracking wood. Moisture-resistant, not easily deformed, moisture-proof timber is excellent.

Cons: Carbonized wood is not suitable for touch with the soil and water environment, compared with untreated material, nail holding power drops, it is recommended to use the first punch and then nail holes to reduce and avoid installing wood cracking. Wood is recommended for outdoor use with UV wood oil to prevent considerable period of time after the timber fade.

Application: railings, pavilions, pergolas, tables, chairs, etc.

Wood Plastic Composite

WPC is also called wood plastic composite materials, people can understand the name easily that raw material is plastic and a replacement for wood. WPC is made of plastic and wood chips made in accordance with the approximate ratio of 1:1. Its application can save a lot of natural wood, help protect the environment, because of the composition of natural fibers, wood has a better resistance to UV (ultraviolet) performance and lower thermal expansion and contraction performance.

Pros: WPC has antiseptic properties, is more difficult to crack than wood preservative, mildew, greener, longer service life characteristics, suitable for use in harsh outdoor conditions. Relative logs, wood materials, better stability, with easy installation, no paint coloring advantages. Because of its surface on the exterior of the wood texture with simulation and color perception, and therefore become the eco-friendly alternative to wood-based materials.

Cons: Although visually similar to wood, but it is difficult to reach and touch wood's natural characteristics, such as: texture monotonous, single color, unnatural and so on. And relatively easy in terms of wood processing, is not free to be processed into the desired shape, thus further affecting its aesthetic properties.

Application: flooring, siding, railing, gazebos, pergolas, lounge chairs, gardening pieces (flower boxes, flower beds)

New Natural Outdoor High Resistance Bamboo

Outdoor high resistance bamboo, bamboo is cut into thin filaments homeopathy, after dehydration, high temperature and pressure, with wear, corrosion, high stability of the new high-tech outdoor timber. In the same size of timber and bamboo, bamboo is generally 2 times of wood on compressive strength, bamboo is generally 8-10 times on tensile strength. Bamboo is for a variety of outdoor environments floor, wall decoration.

As fast growing bamboo, old saying: a hundred years a wood, four contained a bamboo, is subject to environmental resource constraints outdoor upscale hardwood good alternative materials, it is full of green building materials. In 2010 World Expo, many people know it, outdoor bamboo has become a lot of high-end properties and outdoor landscape, the new darling of the courtyard.

Pros: Corrosion resistance of high strength and wear resistance, anti-termite, fire retardant, high hardness, outdoor bamboo is an excellent outdoor material. Excellent dimensional stability and high compressive strength, high density, so that it can easily cope with harsh outdoor heat, cold, dry and other special circumstances.

Cons: Because such materials in the outdoor landscape in the application is still in its infancy stage, so the cost is high. In the production process does not add any coloring agent, and thus its single color, generally brown.

Application: Outdoor wall cladding, outdoor furniture, outdoor fence.
