The Advantages of Wood as a Building Material

Wood is one of the oldest building materials, and it is still one of the most widely used. It is strong for its weight, it can be regrown, and it stores carbon while it stands in a building.

Despite the arrival of steel, concrete, and engineered products, wood’s environmental and performance benefits keep it a common choice for builders and architects worldwide.

Wood is both a common and a historical choice as a building material. Yet, in the past few decades there has been a move in favor of engineered products or metals like aluminum.

While the desire to not rely on the world’s forests for building demands is well-intentioned, it isn’t as eco-conscious as you might think.

In fact, when you look at environmental impact and performance together, wood still compares well with other products on the market.

Wood’s Characteristics

Wood’s value as a building material goes beyond any single property, such as its strength, its resistance to electricity and heat, or the way it handles sound.

It is the combination of appearance, function, and sustainability that sets wood apart.

Tensile strength

Though wood is a lightweight building material, it outperforms even low-carbon steel when it comes to breaking length (or self-support length), the length a material can reach before it breaks under its own weight. Simply put, wood loaded along the grain can support its own weight better, which allows for larger spaces and fewer necessary supports in some building designs.

Electrical and heat resistance

Wood has a natural resistance to electrical conduction when dried to standard moisture content levels, usually between 7% and 12% for most wood species.

That resistance changes with moisture content, which is the basis for pin-type moisture meters. Wood also expands very little when heated, so temperature changes alone don’t change its dimensions much. Its moisture content has a far bigger effect on its size.

Sound

Wood is widely used in acoustic panels, ceilings, and wall treatments to help control echo in living and office spaces, which can make a room quieter and more comfortable.

Beauty

Because there are a wide variety of species available, wood can suit many aesthetics. Different species can also provide varied mechanical, acoustic, and thermal properties.

Wood’s Green Advantage

We live in a time when ecological concerns are high. Because of this, the trend for a time was to move away from wood as a building material to prevent deforestation and manage greenhouse gases.

But a closer look at the reasons for this thinking shows it can be off track. Wood has several advantages that help both the builder and the environment.

Wood is Renewable

Unlike concrete or metals, wood is a building material that can be grown and regrown through natural processes such as replanting and forestry management programs. Selective harvesting and other practices allow growth to continue while larger trees are harvested.

While forests grow, they also remove carbon dioxide from the air, and much of that carbon stays stored in the wood after it becomes lumber.

Wood is Readily Processed for Use

Turning trees into lumber generally takes less energy than producing steel or concrete.

Many lumber mills use wood byproducts (chips, bark, etc.) as bio-fuel for their facilities. This reduces the fossil fuel burden of the production process. Also, in-line moisture measurement systems help mills dry lumber more evenly and produce less subgrade material and waste in the drying process.

As forest management and replanting programs continue to grow, these benefits multiply.

Wood and Indoor Air Quality

Solid wood releases only small amounts of natural compounds, such as the terpenes that give pine and cedar their scent. The bigger indoor air concern is adhesives. Some engineered and composite wood products can release formaldehyde from the glues that hold them together, so look for products that meet low-emission standards such as the EPA’s TSCA Title VI rule for composite wood.

Wood Enhances Energy Efficiency

Because of its natural cellular structure, wood conducts heat far less than steel or aluminum. That means wood framing loses less heat through the structure itself, so homes and buildings can need less energy for heating and cooling. Wood can also help buffer indoor humidity to a small degree because it takes on and gives off moisture.

Wood is Biodegradable

One of the biggest challenges of many building materials, including concrete, metal, and plastics, is that when they are discarded, they take an extremely long time to decompose. When exposed to natural climate conditions, wood will break down much more quickly and actually replenish the soil in the process.

On the flip side, when wood is kept dry and protected from rot, a building or floor can last longer than the tree it came from lived.

Wood as a Building Material

Considering wood as a building material presents a significant advantage in terms of sustainability. Compared to other traditional building materials like concrete or metals, wood stands out because it is renewable.

Through responsible forestry management programs, trees can be harvested and replanted, keeping a continuous supply without causing significant harm to ecosystems.

Energy efficiency is another benefit. Because wood conducts heat far less than steel, wood-framed structures can need less energy for heating and cooling, which helps reduce a building’s carbon footprint.

What are the Uses of Wood in Building Construction?

Wood is used extensively in construction due to its versatility and beneficial properties. Its uses include:

Structural Components

Wood is commonly used for structural elements such as beams, rafters, and joists. Its strength and resilience make it suitable for load-bearing applications.

Flooring

Hardwood floors are popular for their durability and appearance, and they can add to the appeal of a home or commercial space.

Walls and Partitions

Wood is used for framing and creating partitions in interior spaces because it is lightweight and easy to handle.

Roofing

Wooden shingles or shakes are often used in roofing for their attractive appearance and insulative properties.

Doors and Windows

Due to its workability, wood is a preferred material for doors and windows, offering good insulation and visual appeal.

Furniture and Cabinetry

Wood’s diverse range of species, each offering unique colors and grain patterns, is ideal for crafting furniture, cabinets, and other interior fixtures.

Optimizing Wood’s Use with Moisture Content Measurement

One of the most important elements for maximizing wood’s performance over time is having an accurate understanding of wood’s interaction with moisture.

The first step in preventing moisture-related damage in wood floors and other wood-based building materials is bringing each product to the correct moisture content level.

This process begins at the sawmill kilns and carries on through to each finished building application. At each step, accurate moisture content measurement is what tells you the wood is ready.

FAQs

Why is wood considered a renewable building material?

Wood is considered renewable because it can be regrown through natural processes, including selective harvesting and forestry management programs. As forests grow, they remove carbon dioxide from the air, and the wood stores that carbon for as long as it lasts.

How does wood enhance energy efficiency?

Thanks to its natural cellular structure, wood conducts heat far less than steel or aluminum. That means less energy is needed to heat and cool homes and buildings.

Is wood an eco-friendly building material?

Yes, wood is an eco-friendly building material. It’s renewable, generally takes less energy to produce than steel or concrete, stores carbon, helps with energy efficiency, and is biodegradable.

What is the Importance of Wood?

Wood’s significance spans various industries, including construction, furniture, and energy production. Wood is a prized resource in architecture and building for its high strength-to-weight ratio, insulation properties, and workability.

What is the Most Important Use of Wood?

While wood serves many purposes, its most significant use is arguably in the construction industry as a structural material. Wood framing forms the backbone of most residential buildings, particularly in countries with abundant forest resources like Canada and the United States.

Wood’s strength, light weight, and ease of use make it ideal for creating the underlying structure of buildings, and its resistance to electrical conduction and low heat conduction make it a comfortable material for homes and offices.

Why the focus on moisture content?

On the job site, wood needs to reach equilibrium moisture content (EMC) with its surroundings. If builders or flooring installers begin the project before the wood has adjusted to the relative humidity, they run the risk of the wood warping, twisting, splitting, or having significant gaps or buckling.

The right tool for monitoring wood moisture content (MC) is a quality wood moisture meter.

Overall, wood has some “built-in” advantages. It has both environmental and aesthetic appeal. With the right application of wood moisture content management, wood can keep those properties for generations.
