Are Lam Posts better than Solid Sawn?

Both options can provide the necessary support and durability for your post-frame building.

When it comes to the age-old debate of Lam Posts Vs Solid, the pros and cons of each type of post must be considered. Lam posts are composed of multiple layers of laminated wood and offer a greater strength-to-weight ratio than solid sawn posts. On the other hand, solid sawn posts are made from one piece of wood and provide a more traditional look and feel. This blog post will compare the two types of posts and provide a comparison guide so that you can make an informed decision when choosing the best post for your project.

Lam Posts Vs Solid Sawn Posts: Pros and Cons

What’s the difference?

Solid sawn posts and Lam posts are two different types of materials used in outdoor construction projects such as fences, decks, post frame buildings, and pole barn buildings. 

Solid sawn posts are made from a single piece of wood that is cut or sawn into the desired shape and size. This traditional method of construction provides a classic and rustic look. Solid sawn posts are known for their strength and durability, making them a popular choice for projects that require heavy-duty support in exterior applications.

Lam posts, on the other hand, are made from multiple layers of laminated wood that are bonded together under pressure. This process creates a strong and stable material that offers a high strength-to-weight ratio. Lam posts are often used in projects where weight is a concern, as they are lighter than solid sawn posts. They also are less prone to warping or twisting.

Choosing between solid sawn and lam posts depends on several factors, including the specific project requirements, budget, and personal preferences. While solid sawn posts offer a more traditional and sturdy look, lam posts provide greater strength and are easier to work with. It’s important to consider the pros and cons of each type of post before making a decision.

Types of Lam Posts

Mechanically Laminated Post: An assembly where layers are fastened using nails, screws, bolts, or shear transfer plates (metal connectors with teeth).

Structural Glued-Laminated Timber Post (Glulam Timber Post): Layers joined with structural adhesive for increased strength.

Nail-Laminated Post: Interchangeable with mechanically laminated post if nails are the sole fasteners.

Vertically Laminated Post: Designed to resist loads parallel to contact planes; commonly seen in mechanically laminated posts.

Horizontally Laminated Post: Primarily resists loads perpendicular to interlayer planes, as seen in most glulam beams.

Unspliced Post: Layers consist of single dimension lumber pieces; no end joints present.

Spliced Post: Includes layers with multiple lumber pieces, often using glued finger joints or simple butt joints.

Every laminated post fits at least three categories; e.g., a horizontally glued-laminated post without end joints.

Pros and Cons of Solid Sawn Posts

Solid sawn posts have been a popular choice in outdoor construction projects for many years due to their durability and classic look. Here are some pros of using solid sawn posts:

1. Strength and durability: Solid sawn posts are made from a single piece of wood, making them strong and able to withstand heavy loads. This makes them a great choice for projects that require heavy-duty support, such as fence posts, post frame buildings, and pole barn buildings.
2. Classic appearance: Solid sawn posts provide a traditional and rustic look that many homeowners and builders appreciate. They add a sense of charm and character to any outdoor structure.
3. Cost-effective: In general, solid sawn posts tend to be more affordable than lam posts, making them a budget-friendly option for those looking to save on construction costs.

Here are the cons of solid sawn posts:

1. Prone to warping and twisting: Solid sawn posts, especially when exposed to moisture and temperature changes, can warp or twist over time. This may require additional maintenance and repairs to keep them in good condition.
2. Limited lengths and sizes: Solid sawn posts are limited in length and size due to the availability of large, single pieces of wood. This can sometimes limit the design possibilities for outdoor projects.
3. Potential for insect damage: Solid sawn posts may be more susceptible to insect damage compared to lam posts, especially if not properly treated or maintained. This can weaken the structural integrity of the posts over time.

Overall, solid sawn posts are a tried and true choice for outdoor projects, offering strength, durability, and a classic appearance. However, it’s important to consider the potential drawbacks and make an informed decision based on your specific project requirements and preferences.

Pros and Cons of Lam Posts;

Lam posts are a popular choice for post frame buildings because of their strength and stability.

Benefits of Lam Posts:

• Lam posts are less likely to warp, twist, or split compared to solid sawn posts.
• They have a uniform size and shape, which makes installation easier.
• They are easier to notch trusses into by leaving the middle board loose for the builder to custom cut.
• They are less prone to decay and insect damage because each 2x board can be treated individually.

Drawbacks of Lam Posts:

• Lam posts can be more expensive compared to solid sawn posts.
• They may not have the same natural look as solid sawn posts, which some people prefer.
• They are not suited for exterior applications unless they are wrapped with another material
• They are not quite as environmentally friendly as solid sawn posts, as they require more energy to produce.

Overall, lam posts are a great choice for structures where strength, durability and ease of install are a top priority. However, they may not be the best choice for those on a tight budget. Also it may not be the best choice for those who prefer a more natural look, such as on a porch or deck. Consider your specific needs and budget to determine which option is right for you.
