What is the Post-Frame Advantage, and why will it benefit you?

Post-frame buildings are wood-framed buildings. They feature large, solid-sawn posts or laminated columns instead of wood studs, steel framing or concrete masonry. However, studs, steel and masonry may be incorporated into post-frame structures to make unique “hybrid” buildings.

Post-frame buildings may utilize trusses, rafters, or laminated lumber to support roof loads, which may be affixed to each post or supported by a header. Horizontally-placed dimension lumber - roof purlins and wall girts – hold the posts and trusses or rafters together to form the basic frame. Exterior sheathing - commonly steel, OSB or plywood - provide lateral load resistance, creating a unique building diaphragm that makes the light wood frame comparable in strength to steel and concrete structures.

Post-frame structures are much more quickly erected than other kinds of buildings. Because the larger posts and the interlocking frame can handle greater loads than stud-wall construction, less structural materials are needed – which saves on material and installation costs. Pre-assembled roof trusses are often used, which are quickly secured to the frame. The significant savings in construction time and materials means you can have the quality building you want, in less time, for less money.

The savings don’t end with the construction process itself. The natural insulating properties of a wood structure are superior to those of steel or masonry. Also, because posts are spaced farther apart than studs, there are fewer interruptions in insulating materials. Post-frame buildings feature an exceptionally large wall cavity for ample insulation, which allows for lowered heating and cooling costs throughout the year.

Post-frame buildings are durable, long-lasting, and highly flexible in their application. Once constructed, post-frame buildings are also exceptionally resistant to wind, snow and seismic loads. The entire structure works as a diaphragm to allow superior resiliency. Trusses are typically attached directly to posts, making it virtually impossible for the roof to detach from the building. In areas ravaged by hurricanes and earthquakes, often the only structures left standing are post-frame.

Due to the application of modern structural engineering principles and stress testing methods, post-frame technology is recognized as a truly significant advancement in the centuries-old art of wood-frame construction. Post-frame is now the construction method of choice for any number of commercial, retail, industrial, residential, religious and public building needs.

Countless structures are now erected using post-frame methods, including strip malls, convenience stores, restaurants, multi-family housing and office complexes. Schools, churches, banks, fire stations, airplane hangars, and many other kinds of structures may also be erected using post-frame design. Many choose post-frame for homes, residential accessory buildings, garages, workshops and storage buildings.

Due to the nature of its design and many external façade options, post-frame may be customized to provide the look you want. Post-frame is an effective and versatile choice for building additions and remodeling projects; entire buildings may be given a new look, without sacrificing the original building. Almost any type of exterior façade may be installed on a post-frame building.

Post-frame design has proven so efficient and versatile that the agricultural building market, where post-frame was first introduced, now constitutes a fraction of the total post-frame industry. Post-frame design is recognized by building codes and standards for all types of building applications.

Post-frame buildings transfer loads to the ground through the posts, which are typically embedded in the ground or surface-mounted to a concrete pier or masonry foundation. There are a variety of foundation options unique to post-frame, such as plastic barrier systems for enhanced protection of wood, and concrete posts or piers.

People today are concerned about sustainability and environmental impact when it comes to construction. Post-frame buildings are the most “green” buildings you can build, not only because of the renewable aspects of wood and the recyclable nature of steel, but because efficient use of materials and long-term energy efficiency is superior compared to any other type of structure.

As with any type of building, the choices we make regarding quality of materials and workmanship ultimately determine the durability and value of any structure. Post-frame’s unique qualities provide maximum value with efficient use of materials. Choosing a contractor who will stand behind his work and has specialized knowledge, expertise and experience using proven products is key to satisfaction.

Post-frame buildings may be designed to meet the highest standards for quality and aesthetic beauty, and are the most efficient and economical choice for most low-rise building applications. Whatever interior or exterior look you prefer, post-frame can meet the challenge. For all kinds of buildings two or less stories tall, from small garages to clear-spans as wide as 106 feet, post-frame is an excellent choice due to its many inherent advantages.
