When Should You Use Pressure Treated Lumber?

What is Pressure Treated Lumber? 

Pressure treated lumber is a staple in both residential and commercial construction, known for its durability and resistance to decay, insects, and other environmental factors. Understanding when and why to use pressure treated lumber can significantly impact the longevity and safety of your building projects. 

Whether you’re a contractor working on a large-scale development or a homeowner embarking on a DIY project, knowing the appropriate applications for treated lumber is crucial. Here’s a detailed look at where and why you should consider this type of lumber for your construction needs.

Treated lumber is wood that has been infused with chemical preservatives under high pressure to protect it from rot, fungal decay, and termites. These chemicals penetrate deep into the wood, providing effective long-term protection, which makes treated lumber an ideal choice for many outdoor and structural applications.

Key Applications for Pressure Treated Lumber

Outdoor Projects

Due to its resistance to moisture and decay, pressure treated lumber is particularly well-suited for outdoor projects. This includes decks, fences, garden beds, and outdoor furniture. The chemical treatment ensures that the wood withstands the elements far better than untreated wood, preventing rot and extending the life of the project. This includes rain and humidity. 

Structural Uses

For any building projects where the lumber will be in contact with the ground or exposed to moisture, pressure treated wood is essential. This includes the sill plates in home construction, which sit directly on the concrete foundation and are susceptible to moisture coming up from the ground. Using pressure treated lumber in these structural components can prevent premature rot and structural damage, potentially saving homeowners significant repair costs down the line.

Framing for Raised Garden Beds

Gardeners often use pressure treated lumber for constructing raised beds. The chemical preservatives prevent soil moisture and pests from damaging the wood. This is especially important when the wood will be in constant contact with moist soil and outdoor conditions.

Support for Outdoor Structures

Structures such as pergolas, gazebos, and trellises benefit from the use of treated lumber due to its strength and resistance to decay. These structures are exposed to the elements throughout the year. Using treated lumber helps ensure their durability and longevity.

Considerations When Using Pressure Treated Lumber

Safety First

While modern pressure treated lumber is much safer than its predecessors, it’s still important to handle it with care. Wear gloves, masks, and protective eyewear when cutting or sanding this type of wood to avoid inhaling sawdust or getting preservatives on your skin.

Sealing and Maintenance

To maintain the appearance and integrity of pressure treated lumber, it’s advisable to seal it with an appropriate sealant. This not only helps to lock in the preservatives but also prevents the wood from drying out. 

Proper Disposal

Due to the chemicals used in pressure treated lumber, it should never be burned. Dispose of offcuts and waste according to local regulations, often by taking it to a registered landfill or recycling center. 

Installation Tips

When using pressure treated lumber for framing or installing custom doors, ensure that you use fasteners—such as nails and screws—that are rated for use with treated wood. Ordinary fasteners can corrode in contact with the preservatives, compromising the structural integrity of the project.
