I. Pressure Treated Wood

1. What is Pressure Treated Wood?

Pressure-treated lumber is a material made from wood fibers or particles pressed together to form cohesive elements. There are a lot of chemicals put in as preservatives—some preservatives such as copper or plastic.

Although pressure-treated lumber is inexpensive and highly versatile in use with homeowners. It is not considered strong and durable, and it can break quite easily when subjected to excessive loads.

Pressure-treated wood has a variety of functions. The wood grains are pressed together, and an adhesive is used to form a cohesive structure.

Wood is relatively light, and it is durable to some extent. However, chipboard can chip quite quickly, so wood veneer is often glued over it to prevent damage from direct impacts. Veneers can mimic the grain and tone of solid wood, which means this wood product can be made to look reasonably attractive.

2. Advantages of Pressure Treated Wood

a. Low Cost

Pressure-treated lumber is considered material at an affordable cost. The average price is $15 per square foot. Along with that, the input materials of pressure-treated wood are also easy to find and cheap, so the price of industrial timber is much lower than that of natural wood. This is also one of the leading reasons why customers increasingly trust industrial lumber. Homeowners can save a lot of money by taking good advantage of it.

b. Mass-produced – Fast Construction

Pressure-treated lumber sold on the market comes in panels with standard sizes, and needs to be cut, grafted, and glued when manufacturing furniture; the construction time is quick and can be mass-produced with identical models.

3. Disadvantages of Pressure Treated Wood

The pressure treatment process makes the lumber become a solid board. However, the pressure-treated lumber doesn’t bring a lot of benefits when it comes to the outside deck. Rot, fungal decay, and termites are a nightmare for homeowners.

a. Incest

Incests, like termites, are complicated to recognize because they often create small holes from deep inside, causing the wood to rot; the wood structure is also damaged. No matter how tight and stiff the lumber is made, it can still be eaten as usual. Because insect do not use their teeth or bite as we think, but in their body, there is an extreme acidic fluid, which, when secreted, will soften the wood and decompose the internal structures.Termites

b. Moisture

Pressure-treated wood doesn’t have a high water-resistant. The climate is hot and humid, with high humidity and high temperature, so a sudden temperature change will cause ordinary pressure-treated wood to crack or become fungal decay when the temperature changes. Fungal decay takes a large budget to repurchase because you can’t fix it. If they expose to ground contacts, such as water or leaf, the wood deck boards can be damaged.

c. Short Warranty

With low-quality boards like pressure-treated wood, it has a short-term warranty. A majority of pressure-treated wood products don’t come with a warranty.

4. Types of Pressure Treated Wood

a. Melamine-Faced Chipboard (MFC)

MFC is made of a wood core layer and covered with wood grain, the manufacturer also paints the surface. The majority of office furniture is produced with this material. That’s why these boards are hard to stain.

b. Particle Board


Particleboard is a type of wood core made from the trunks of planted forest trees such as eucalyptus, rubber, acacia, etc., which are put into the machine to be crushed into chips. After that, the finished wood chips are mixed with glue and pressed under temperature to produce wooden boards with different standard thicknesses. After that, the chipboard can be coated with decorative surfaces such as Melamine, Veneer, Acrylic, etc., to be closed into the interior and exterior products.

c. Ply Wood

Plywood is one of the innovative treatments of the industrial wood industry. Plywood is made up of many thin layers of wood arranged continuously perpendicular to each other along the path of the wood grain. These thin layers of wood are glued together with specialized glues such as Phenol or Formaldehyde glue under the influence of heat and pressure. These thin layers of wood are bonded together into a single pattern called Plywood. You can stain it quite easily since there is no outer protection.

II. How Can We Use Pressure Treated Wood?

2. Durability

Durability is the number-one requirement for composite decking. Pressure-treated wood needs to store in a dry environment. With outdoor construction or a building like a patio deck, the deck board surface will have ground contact with water, which can cause the board to rot, which requires a lot of maintenance every year. Decking needs high durability; otherwise, it can cause you a fortune just for deck board maintenance only.

Composite wood has a unique treatment process. During the manufactured process, the factory adds plastic to the boards. It is commonly used for decking because of its durability. Besides, composites products usually come with a warranty due to the high price.

Although composites are expensive, it is a worthy investment for your deck project. These deck boards are resistant to ground contacts, such as water, insects, fungal decay, or moisture; also, they cannot rot quickly. Because it has an outer chemical layer as a protection, it cannot be stained when exposed to the environment. People can clean it with a regular cleaning agent once every year to maintain the deck board’s color.

Various brands have different sizes and widths; you can customer the right deck board for your home.

2. Natural Wood Deck

High-grade wood like cedar or oak is an excellent choice for building a deck. Typically, a natural wood deck board can last for at least 25 years with proper maintenance techniques. The high-grade wood board still has disadvantages, such as physical and mechanical changes when changing weather, such as warping, expansion, discoloration, or even mold.

Wood flooring has many advantages, such as having a hard surface, good deck pressure resistance, and high resistance to friction and wear. High-quality treated wood materials have a beautiful finish, are free of harmful substances, and are always eco-friendly. Because wood is a poor conductor of heat, wooden floors always keep the right temperature for your space. A wood deck board can stay warm in winter and cool in summer, giving family members a pleasant and refreshing feeling when in contact with wood floors.
