When someone says timber frame home design you tend to get one of two reactions. With this type the timber frames comprise of large prefabricated frames or cassettes typically 2. Typically they come with the breather membrane attached to the outer side, but without the insulation or vapour control barrier which goes on the inside being fitted.

The Advantages of Wood as a Building Material

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

Tensile strength — For being a relatively lightweight building material, wood outperforms even steel when it comes to breaking length or self-support length. Simply put, it can support its own weight better, which allows for larger spaces and fewer necessary supports in some building designs.

This conductivity is, in fact, the basis for one type of moisture measurement system. Its strength and dimensions are also not significantly affected by heat, providing stability to the finished building and even safety implications for certain fire situations.

Wood absorbs sound, rather than reflecting or amplifying it, and can help significantly reduce noise levels for additional comfort. Beauty — With the wide variety of species available, wood presents an incredible range of aesthetic options, as well as provides varied mechanical, acoustic, thermal properties along with others that can be selected based on the need of the building project.

At a time when ecological concerns are high, the trend has been to move away from wood as a building material in order to prevent deforestation, in part as an attempt to manage greenhouse gasses. However, a closer look at the reasons for this thinking can prove to be slightly off track. Wood has several advantages that help both the builder and the environment. Unlike concrete or metals, wood is a building material that can be grown and regrown through natural processes and also through replanting and forestry management programs.

Select harvesting and other practices allow growth to continue while larger trees are harvested. While the forests are growing via solar energy , they are also naturally and efficiently removing carbon dioxide from the environment.

When compared to building materials like steel or concrete, the life cycle of wood has a lower overall impact on the environment than its counterparts and as a result, also costs significantly less to produce. Wastewater production and environmental impact are also significantly lower in wood manufacturing processes, particularly when compared to steel.

Many lumber mills use wood byproducts chips, bark, etc. As forest management and replanting programs continue to grow, these benefits are continually multiplied. As a natural building material, wood emits significantly lower volatile organic compounds VOCs and carbon dioxide off-gasses than aluminum, steel, concrete and plastics. This is not, however, necessarily true of engineered wood products or composite wood products. Wood has a higher insulation rating than either steel or plastic as a result of its natural cellular structure.

This means that homes and buildings require less energy to maintain heating and cooling, plus wood can help regulate humidity levels to a small degree. One source suggests that a hardwood floor installed over a wood subfloor provides the same insulation value as a inch concrete floor.

One of the biggest challenges of many building materials, including concrete, metal, and plastics, is that when they are discarded, they take an impossibly 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, understanding the role of moisture and wood rot means that when conditions for the wood are optimized, the lifespan of the building or floor can easily outlive the lifespan of the tree!

The first step in preventing moisture-related damage in wood floors and other wood-based building materials is in bringing each wood building product to the correct MC level. This process begins at the sawmill kilns and carries on through to each finished building application. Wood is a hygroscopic material. It naturally has a give and take relationship with the humidity in the air around it and is always in the process of trying to find a balance between its internal MC and the ambient conditions around it.

On the job site, wood needs to be in balance with its environment, a state referred to as equilibrium moisture content , or EMC. If builders or flooring installers begin the project before wood has adjusted to the relative humidity levels around it, they run the risk of the wood warping, twisting, splitting, or having significant gaps or buckling.

The meters provide easy-to-use, accurate MC measurements to be sure that every building and flooring professional knows the MC of the wood they will be using in the building process. Consider reading, how to use a moisture meter properly next.

Larry Loffer is a senior technician at Wagner Meters, where he has over 30 years of experience in wood moisture measurement. With a degree in Computer Systems, Larry is involved in both hardware and software development of wood moisture measurement solutions. Last updated on January 15th, Finding a lumber mill that will maximize efficiency and produce less sub-grade waste materials in the drying process is a great idea.

Making sure you have the best building materials could help your project work better and last longer. Wood sounds like a fantastic building material. In my opinion, natural choices are almost always better than man made ones. It does make sense that moist wood could end up being a little bit weaker because it would allow the fibers to bend or even break. Having building supplies that are up to par with health codes and things like that would be pretty important.

Thanks for elaborating on the benefits of using lumber when building. I never really thought about the idea that wood actually absorbs sound and can reduce noise levels. I would imagine that wood can last longer than a lot of other materials if you treat it right as well. I liked that you said that one thing to consider when you are in need of wood is to order through a lumber supply business in order to create beautiful woodwork. I will be sure to buy wood from the lumber supplier to ensure quality in the building of my business.

My husband and I plan to have a mini timber bridge on top of our residential pool. Well, we better start looking for a construction company that can build us our bridge.

Nice write up on wood…. He would really like to get some help from a professional that can get him the right materials to build with. I liked what you said about how other trees can be harvested while allowing more growth and they can have a small impact on the environment. My brother told me that he wants to have a new bridge built on his property and is asking me for advice on what material should he choose. I like that you talked about how using wood is great not only to give a fine appearance but because the material is renewable and will not affect the environment.

W I will definitely pass this information to him so he chooses the best option for his property. If I were to build my house, I think wood would be a great choice for it. Due to it requires less energy to heat and cool. Thank you for the information about the advantages of wood as a building material.
