Composition

What Is Pressure Treated Wood?

Pressure treated wood is made from yellow pine and then covered by a chemical named chromated copper arsenate. Some homeowners are afraid that the chemical coating will somehow do harm to users.
However, according to many professors, it is completely safe because the amount of chemicals used in this type of wood is really small. Pressure treatments only interfere 1/4” to 1/2” into the wood grain.

In comparison with redwood, pressure treated wood will cost less thirty percent or forty percent than the price of redwood.

What Is Redwood?

Redwood originates from Northern California’s redwood forest and is favoured by its red appearance and aesthetics. A high-quality kind of redwood makes this wood capable of resisting weather elements, rot, insects and so on. 

When using redwood to design exterior structures, no chemicals are added, which may create both advantages and disadvantages. 

As its specially luxurious appearance, redwood is quite expensive which makes a lot of consumers hesitate to buy it. Because of its high cost, redwood is mostly constructed for each wood product’s tangible and visible part.

Durability

The Durability Of Pressure Treated Wood

Average durability for redwood lasts thirty years more if you keep it in an appropriate way. It is also impervious to fire which makes it more valuable. 

The woodworkers do not add any chemical treatments in the design process so that the redwood construction product will remain the natural appearance of redwood.

However, the color of redwood will turn black at the initial stage then become grey if it was not coated by any chemical. Redwood can not maintain its shape over time and is prone to warp after a long time of use. 

Compared to pressure treated lumber, redwood possesses many standouts and enhanced characteristics. However, when it comes to durability, pressed treated wood lasts longer than redwood.

Pressure Treated Wood vs Redwood – Strengths and weaknesses 

Here are some weaknesses and strengths of the two types of wood that we find out:

Pressure Treated Wood 

  • Strengths
  • Because this wood is treated with chemicals, it is proof against various external impacts such as insects, fungi, mould, especially fungi which redwood can not withstand. 
  • Moreover, using pressure treated lumber is a perfect solution that completely mitigates serious issues with termites. People in South America tend to choose this type of wood because they usually get into trouble with the termite’s issue.
  • It lasts longer than other normal goods and is more durable when used in outdoor conditions.
  • It stands stronger than redwood and is acceptable for framing.
  • The price of pressure treated is affordable and much cheaper than redwood.
  • It will not take them a long time to manufacture and design the pressure treated timber for woodworkers. With some woodscrews, a table saw, and the table saw stand, a pressure treated deck can be completed in a short time.
  • It is available anywhere on the market compared to other types of wood because yellow pine is quickly grown and easily harvested.
  • Weaknesses
  • This wood includes an infusion of chemicals, so care must be taken when handling or sawing this wood. A set of protective solutions such as wearing gloves, safety glasses, or masks must be considered.
  • The pressure treated lumber becomes fader after a long time because of the wear and tear chemical coat. 
  • Its capacity for resisting sunlight is limited.
  • It has an annoying smell at first because it contains chemicals. 

 Redwood

  • Strengths

Hence, this wood could bring to the homeowner a fresh and unique feeling and experience.  

  • Its light mass enables homeowners to easily move and handle. It is specifically convenient for wood makers to constantly move their redwood structures during the manufacturing process. 
  • Unlike the pressure treated timber, it is totally safe for users because it is not coated by any chemical. When it comes to health concerns, people are likely to favor redwood over pressure treated lumber. 
  • Redwood is a natural wood that contains a lot of Tannin, a chemical that prevents rot effectively.
  • Even though redwood is completed with a sealant, it is rather easy to clean this type of wood thanks to its glossy appearance. It is also possible to restore the original colour of redwood thanks to some detergent. 
  • The redwood can be invulnerable to fire. The Homeowners do not have to worry about fire damage. It seems that redwood is the first and foremost choice for safety 
  • Weaknesses
  • Unlike pressure treated wood, Redwood is not edible for making frames because it is not strong enough.
  • The price of redwood is much more expensive compared to pressure treated yellow pine. The average cost for each square foot is around $30.
