What is SPF Used for?
16 Jan 2020 Building Supply
There are many different materials used for framing and building new construction projects, and the most commonly used material is SPF. As one of the most common types of dimensional lumber, SPF is used for construction for framing walls, floors, and ceilings, as well as roofing. At Country Lumber, we know how important it is to have a good dimensional lumber supply for any building project, so we always stock various sizes of SPF.
What is SPF?
SPF stands for spruce-pine-fir. The three types of wood are processed together and can be used in similar situations because they have very similar properties. Spruce, pine, and fir boards can be difficult to tell apart due to their shared appearance and qualities, which is why the boards are often sold together in lumber yards as SPF. All three woods qualify as softwoods, but they are still strong and can support large amounts of weight. SPF is dimensional lumber, meaning that it is typically described and sold by nominal sizes that differ from the actual size of the board (for example, a 2×4 is actually 1.5×3.5 when measured in actual inches). The most common nominal sizes of SPF that can be found in most lumber yards include 2×3, 2×4, 2×6, 2×8, 2×10, and 2×12.
What are the Uses of SPF?
SPF is most commonly used in framing work. It can frequently be found in wall and roof frames, roof trusses, floor joists, and beams. Because of the wood’s softness, the ununiform cuts, and its rough aesthetic quality, it is not typically used in finishing work, furniture, or cabinetry, but many woodworkers still choose to use it and it can be used to make beautiful projects when handled properly; however, if it is going to be used for finer woodworking, it is important to make sure that only one type of wood is used, as spruce, pine, and fir can appear differently when finished with stains or other wood treatments.
SPF is also commonly used for packaging and pallets. When finished properly, some grades of SPF are suitable and even desirable for decking and exterior finishing.
