Advantages of Pressure Treated Sheds

By Gregory Miller

The process of pressure treating timber

To some, pressure treating timber is akin to creating a work of art. There are multiple steps, each precise, but the result is a high-quality product that lasts much longer than untreated wood. During the pressure treating process, the timber is dried naturally using a kiln or air flow.

All moisture is removed from the wood which preps it for the next step. Soon after, the timber is placed in a pressure treatment tank where a vacuum is used to remove all of the air. The tank is filled with a wood preservative, and once the timber has been treated for a sufficient amount of time the liquid is then removed via vacuum. Ultimately, it's the low pressure of the timber that draws in the preservatives deep into the grain, thus creating a fully treated end product.

Typically, you can identify pressure treated timber by its green tinge finish. Pressure treated timber stands up amazingly well against the weather, increasing its longevity. Keep in mind that if you saw or cut away a strip of pressure treated wood, you should immediately coat the exposed ends with a high-quality preservative.

When it comes to sheds, there are dozens of choices that vary by durability, design and other factors (bike sheds and dog kennels also count). It doesn't matter if you have an apex shed, a wooden garden shed with shiplap cladding, or even a simple garden office, there are multiple advantages to buying a pressure treated shed. 

Advantages of pressure treated sheds

1) Longevity

Sheds that are untreated tend to decay at a much faster rate than that of a shed that has been treated with preservatives. As we all know, garden sheds play a vital role in keeping our garden items safe (such as tools, mulch, compost and everything else needed to take care of your garden). With so many valuable items stored away, you shouldn't have to worry about the state of your shed as the years sail by. 

Don't misunderstand, there are plenty of quality untreated wooden sheds out there, but the chemicals used in the process of pressure treatment creates a shield that will allow your shed to last for years to come. Untreated sheds are more susceptible to damage as time goes on. You'll need a shed that will fulfill all of your garden storage needs without the fear of exposing the contents within to the ravages of nature. For this reason, amongst others, pressure treatment is the way to go.

2) Weather-proof

One of the primary advantages of pressure treated sheds is that they're weatherproof. No matter what type of beating mother nature throws at it, pressure treated wood will last for many years. This especially comes in handy if the shed is making direct contact with the ground, where it can be susceptible to damp. The preservatives will once again act as a shield against the ravages of rot and decay associated with damp places.

3) Cost-effective


To save money in the beginning, people look for temporary fixes to protect their sheds from the elements. Let's take temporary surface protection for example. It's a cheaper alternative to purchasing a pressure treated shed and it's fantastic for providing a temporary solution. However, as the name implies, the effects are temporary. As time goes on you'll have to continuously treat your shed with more and more surface protection. Over time the expenses begin to pile up and you'll suddenly wonder how you ended up throwing away so much money. When it comes to pressure treated sheds however, you'll only have to spend money one time (at the cash register). Every aspect of pressure treated sheds have been infused with quality wood preservatives, both inside and out, thus  continuous treatment is not necessary.

It's no secret that pressure treated sheds are more expensive up front. If you're looking to save a bit of money, there are multiple varieties of pressure treated timber that's easier on the pocketbook. Even if you have a preference for higher quality pressure treated timber, you'll still save money in the long run because of its longevity and low maintenance. Compare that to the cost of replacing untreated wood due to decay and rot, and you'll find that pressure treated timber is the more cost-effective choice. 

4) Durable

Pressure treated wood is much stronger than wood that has not been treated. In fact, pressure treated wood can withstand a significantly stronger physical impact then it's non-treated counterpart and is more difficult to damage overall. When pressure treated timber board is used as construction material for a shed, you can rest assured that you'll have an amazingly solid structure with a smooth wood finish.

If you're looking to add further durability to your shed, you should consider purchasing a base. Base laying keeps your shed from making direct contact with the ground, keeping it safe from bugs, moisture and thus making it more durable overall.

5) Low-Maintenance

On top of everything else, pressure treated sheds are low maintenance. Essentially, all of your maintenance needs were taken care of during the pressure treatment process. With the preservatives firmly ingrained into the very core of the wood itself the structure will be impervious to water, pests, termites, etc. Pressure treated sheds can withstand all types of weather conditions, dampness from the ground, and various other conditions that would cause you worry if you had an untreated shed. Once your pressure treated shed has been installed in your backyard, you can basically forget about it for a long time without issue.

6) Environmentally Friendly

Environmentally Friendly

In most cases, the terms "environmentally friendly" and "chemicals" stand opposite to each other, not side by side. In this case, the chemicals used to preserve pressure treated timber have a number of qualities that make it beneficial to the environment. For one, due to the increased lifespan of pressure treated wood, fewer trees are harvested to produce more pressure treated sheds. Sure, the effect on the environment may seem minimal from the surface (other industries will continue their deforestation practices), but every tree saved makes a difference.

Furthermore, preserving wood uses less energy than other methods of producing the supplies that we use to construct buildings (a number of which can be considered non-friendly to the environment). Finally, the primary chemical used in the pressure treating process is copper. Copper is a byproduct of recycling and would be otherwise discarded if it weren't used for pressure treating timber.

7) Decorative

This last benefit is purely aesthetical. Pressure treated timber takes on a natural green tinge that gives it an "all-natural" look. However, if natural green isn't exactly your thing, you can paint over the smooth matte surface with any color that you like. From overlap sheds to pent sheds, the design choice is completely up to you.

Pressure treated sheds are the superior choice

Pressure treated sheds are a great investment due to their many advantages. They're environmentally friendly, they save you money in the long term, they have great aesthetical appeal, and they're low-maintenance. What more could you want from your shed? Keep these factors in mind when you're shopping for your next shed, and you might just save yourself years of frustration and upkeep costs by making a smart and well-informed purchase.

Questions you should ask yourself before picking a pressure treated shed

Pressure treatment is only one part of the equation when it comes to picking out the perfect shed. Here are a few important questions that you should ask yourself before making a purchase: Does it have a shed base? What is the roof style? Is it heavy duty? Does it have a single door? Double doors? Do the doors use a hasp and staple latch? What type of cladding does it have? Is it tongue and groove? What about shiplap sheds? Shopping for a shed can be a daunting task.
