Timber for Structural Frames
Timber is widely used for structural framing due to its strength, versatility, and sustainability. One of the main reasons timber is so effective for structural framing is its high strength-to-weight ratio. This means it can bear significant amounts of weight without breaking or becoming too heavy, making it easier and more cost-effective to handle and transport on-site.
Traditional solid timber is a popular choice for framing, particularly in residential housing. Solid timber is often used for framing components such as wall studs, floor joists, roof rafters, and beams. Products such as laminated veneer lumber, glue-laminated timber, and cross-laminated timber are just as strong as solid timber, and they're also not prone to warping or splitting.
Wall Studs and Partitions
Timber is commonly used for wall studs and partitions because of its strength, adaptability, and ease of use. Timber can provide reliable structural support while being lightweight, meaning it can be transported and installed easily on-site. Timber studs can be cut to size with standard tools, allowing builders to make quick adjustments during the construction process.
Timber is also highly adaptable, which makes it ideal for internal partitions. It can be used to frame walls of various heights and thicknesses, and it can accommodate electrical wiring, plumbing, and insulation with ease. Builders can also adjust timber frames to suit any design changes or specific layouts, which is especially useful in renovations or custom build projects.
Timber is also a natural insulator. When timber is used in wall studs and partitions, it can help improve the thermal and acoustic performance of a building. Additionally, by adding extra insulation between the studs, timber-framed walls can meet or exceed most energy efficiency standards.
Timber in Flooring Systems
Timber is a popular and reliable material for flooring systems due to its strength, durability, and easy installation. Structurally, timber is often used to create the subfloor, which is the foundational layer that supports the finished floor surface. Solid timber joists and beams are also commonly installed to span across the walls or piers to create a strong framework. These joists are spaced evenly and are covered with timber or plywood sheeting to form a stable base for carpets, tiles, hardwood, or other flooring materials.
Engineered timber products like laminated veneer lumber and I-joists are also widely used in modern flooring systems. These products are designed to be stronger and more dimensionally stable than traditional solid timber, allowing builders to create longer spans and flatter floors with less risk of warping, shrinkage, or movement over time. This results in quieter, more even floor and allows for open-plan layouts without the need for excessive support.
Roofing with Timber Trusses and Beams
One of the main reasons timber is used for roofing is its excellent strength-to-weight ratio. Timber trusses and beams can support substantial amounts of weight, including the weight of roofing materials, insulation, and wind or snow.
Timber trusses are pre-fabricated structural frameworks that are typically made of interconnected triangles. This design is ideal for ensuring the framework is strong and that it distributes loads across the structure evenly. Timber is commonly used to make king posts, queen posts, and fink trusses, which are each suited to different spans and roof pitches. These trusses can be manufactured off-site and delivered on-site, which helps reduce the construction time and your labour costs.
Beams are horizontal components that support roof loads and transfer weight to vertical supports like walls or columns. Solid timber beams are often used in traditional roof construction, while engineered timber products like laminated veneer lumber are used more in modern builds. These engineered beams are stronger and provide better dimensional stability, allowing builders to create longer spans and more open interior spaces.
