Pressure wood treatment is a process commonly used for building materials in today's industry. Pressure treated timber can be used for various purposes such as making garden furniture, as with it comes some unique benefits. On the other hand, there are a number of demerits associated with this kind of timber. Below is a look at the pros, cons as well as controversy surrounding the method and pressure treated wood.

Pros

One of the main merits of wood that has been pressure treated is that it is quite affordable. When a comparison is made with other types of timber, this type is a bit cheaper. For instance, if compared with redwood, a saving of between 30 and 40 of the cost is made. If the user is working on a large-scale building project, he or she can make a significant saving. For those working with a tight budget, this kind of timber should be very attractive.

Another major merit of timber that has been pressure treated is that it is strong. It should be able to resist wear and tear better than other kinds of timber. This is because it is a lot harder to scratch or dent pressure treated wood.

As a result of the extra strength, this kind of wood is likely to last a very long time. The owner of furniture or material made using this kind of timber will not have to replace them any time soon once purchased. As a matter of fact, there are numerous manufacturers who put a 40-year plus warranty on the wooden materials they produce.

Pressure-treated timber is infused with chemical preservatives that protect it from insects and rot. This means insects will not be attracted to products made using the materials. They are actually toxic such that if an insect spends too much time on them or tries to bite them they die. As a result of this, rodents and insects will generally stay away from the wooden products or furniture.

Cons

As much as there are many pros of this type of timber, a number of drawbacks exist as well. The toxicity of the materials contained in the wood can be dangerous. This means that any individual who is directly exposed to them or comes into contact with them in any way can suffer from health-related consequences. If such wooden products are burnt, toxic chemicals will be released into the air, leading to pollution. Should a structure made using such material catches fire, the owner will have to worry about both the fire and the chemicals released from the combustion process.

Controversy

For quite a long time, CCA (Chromated copper arsenic) has been the chemical used to preserve timber. This has led to uproar and controversy, considering the extremely toxic nature of this chemical. This has caught the attention of some environmental campaigners who have since then started a strict oversight of practices applied by firms using CCA. While debate continues concerning the toxicity and safety of chemicals used in timber preservation, the controversy will definitely continue until safer methods are introduced.
