Demystifying Trusses, Sheathing, Lumber, And Engineered Wood: A Guide For Homeowners

Building a home is an exciting process but can also be overwhelming with all the technical terms and materials involved. One crucial aspect of constructing a sturdy and durable home is understanding the different components that make up its structure. We will delve into the world of trusses, sheathing, lumber, and engineered wood – four essential elements in home construction. By the end of this guide, you will better understand these materials and their role in building your dream home.


Let’s start with trusses – one of modern homes’ most commonly used structural elements. Trusses are prefabricated triangular frames made of wood or steel that support the roof and stabilize the overall structure. They come in various designs to cater to different architectural styles and can be customized according to specific needs. Trusses have increased over traditional roof framing due to their cost-effectiveness, ease of installation, and ability to span longer distances without additional support.


Next on our list is sheathing – the layer covering the exterior walls and roofs before applying any siding or roofing material. Sheathing is a protective barrier against weather elements such as wind, rain, and snow, adding strength to the overall structure. It comes in different types such as plywood, oriented strand board (OSB), and fiber cement boards. When choosing sheathing material for your home, consider factors like durability, moisture resistance, thermal insulation properties, and fire resistance.


Lumber is one of the most familiar materials used in construction. It refers to any wood product cut or shaped into standardized dimensions for building purposes. This versatile material is utilized throughout a house’s construction – from framing walls and floors to creating beams and columns. The quality and strength of lumber depend on the type of wood species, its grade, moisture content, and structural design.

Engineered Wood

Lastly, we have engineered wood – a modern alternative to solid lumber. It is made by binding strands, particles, veneers, or wood fibers with adhesives to form a composite material that exhibits superior strength and stability compared to traditional lumber. Engineered wood products include plywood, laminated veneer lumber (LVL), glulam beams, and I-joists. They are often used with other materials to create robust and efficient structures.

These four components play a crucial role in building a safe and sturdy home that will withstand the test of time. When planning the construction of your dream home, consult with experienced professionals who can guide you in selecting suitable materials for your specific needs.
