Post Frame Advantages

Our buildings consist of a wood frame with pre-painted steel panels used for roofing and siding. AJ Builders LLC is proud to offer a 40 year paint warranty and a 5 year workmanship warranty. This type of building provides for a long-lasting, low-maintenance, cost effective structure. When choosing the right building for you, consider the five key points below when comparing Post Frame Buildings to other types of construction.

Steel Building

Foundation

A level building site is all that is required to start construction of your building. A steel building will require the additional cost and installation of an engineered concrete foundation to support the steel frames prior to construction of the building. 

Materials

Post Frame buildings incorporates a simplified building geometry with a minimum of materials used to put a given clearspan volume of building under cover. Steel buildings require more building material to produce the same amount of space. 

Insulation

Your post frame building provides an opportunity to up to 10” wall cavities with many different types of insulation options and the attic area allows space for up to 16” of insulation. Steel building insulation is compressed between steel roof purlins and sidewall girts.

Reuse and Adaptability

Any homeowner can renovate or remodel their building with ease using common hand tools. Steel building renovation requires welding.

Design Flexibility

Your post frame building can allow for roof pitches from 3/12 to 8/12 designs, giving you the ability to match your existing building. 
Steel buildings have limited roof pitch options. 

Foundation Requirements

A steel building will require the additional cost and installation of an engineered concrete foundation to support the steel frames prior to construction of the building. Post Frame Buildings: The foundation to have the building columns placed in ground. A level building site is all that is required to start construction of your Post frame building. A concrete floor can be poured after the building has been enclosed, thus reducing concrete exposure to the elements during installation. 

Optimize Material Use

Avoid waste from structural over design and use optimum value engineering. Post Frame Buildings: The basic post frame building design concept incorporates simplified building geometry with a minimum of materials used to put a given clear span volume of building under cover. The use of steel roofing, due to its light weight per unit area, results in structural material savings when compared to using heavier, non-metal roofing alternatives. 

Insulation

Use high levels of insulation and high performance windows. Post Frame Buildings provide an opportunity to fill up to 9” wide wall cavities with many different insulation types to give you the whatever insulation value you hope to achieve. The use of a steel ceiling attached to the bottom chord and the trusses as support allows high R-Values on insulation to be blown into the attic area providing uniform and tight insulation coverage, compared to steel building insulation compressed between steel roof purlins and sidewall girts. 

Reuse and Adaptability

Make the structure adaptable to other uses and choose materials that can be reused or recycled. Post Frame Buildings: The inherent clear span design of post frame buildings naturally creates a structure which can be adapted to multiple uses. Without the requirement of interior support walls, interior room locations and division walls can be changed without requiring structural revision to support the roof system. Any homeowner can renovate or remodel with ease using common hand tools, rather than having to perform any welding. When the initial building design incorporates design provisions for attic ventilation and the support of future ceilings, the unheated warehouse can be easily modified into a heated business, factory or manufacturing facility. 

Design Flexibility

Make sure the building design will allow you to accommodate your design specifications. Post Frame Buildings: The post frame building will allow design flexibility for your roof design, sheathing material, door and window locations. Our building can allow roof pitches from 3/12 to 8/12 designs giving you the ability to match your existing building (business, home, etc.). The exterior siding is traditionally steel, but the framework can utilize other wood, brick and stucco siding options. The openings in the walls of a post frame building can be designed for larger or small door and window designs. The post frame building offers flexibility to finish off the interior of the building when it is convenient for the owner.


Building Life Cycle Cost Benefits


Life cycle cost is a method to determine the entire cost over a product’s intended life cycle. For buildings, the main factors considered are initial cost, operating costs, replacements costs and maintenance or repair costs. Current methods of post-frame construction contain many green elements which support life cycle costs including: reduced site disturbance, less use of wood to create the structural system, engineered systems for the roof structure, a building cavity with room to accommodate insulation to meet International Energy Conservation Code requirements – a must for many green building systems, and flexibility of interior design due to the absence of interior structural columns.


Green Design

Design an energy efficient building: Use high levels of insulation, high performance windows, and tight construction.

Buildings

The provide an opportunity to fill up to 9′ wide wall cavities with up to 10” of any type of insulation.  Use of a steel ceiling attached to the bottom chord of the trusses as support allows high R-Values of insulation to be blown into the attic area providing uniform and tight insulation coverage compared to insulation installed between roof purlins.

Post Frame Buildings

Metal roofing’s reflectivity can help reduce air conditioning loads to save energy by reflecting heat away from the building when light colors are used in the building design.

Optimize Material Use

Avoid waste from structural over design (use optimum value engineering/advanced framing). Simplify building geometry. 

Post Frame Buildings

The basic post frame building design concept incorporates simplified building geometry with a minimum of materials used to put a given clearspan volume of building under cover. The use of steel roofing, due to its light weight per unit area, results in structural material savings when compared to using heavier, non-metal, roofing alternatives.

Minimize soil disturbance and erosion

Post-frame construction requires minimal soil disturbance. This also reduces the foundation costs by using isolated footings only at the columns.

Post Frame Buildings

Engineering specifically calculates the trusses, purlins, columns, and footings for each building’s roof load. Additionally, in some areas the footings must be reviewed at the site to meet stamped plan requirements. The design of the building carries the weight directly from the truss heel, through the column, then to the designated footing under each column.

Design for future reuse and adaptability

Make the structure adaptable to other uses, and choose materials that can be reused or recycled. 

Post Frame Buildings

The inherent clearspan design of post frame buildings naturally creates a structure which can be adapted to multiple uses. Without the requirement of interior support walls, interior room locations and division walls can be changed without requiring structural revision to support the roof system. When the initial building design incorporates design provisions for attic ventilation and the support of future ceilings, the unheated warehouse can be easily modified into a heated business, factory, or manufacturing facility.


Green Materials

Use durable products and materials

Because manufacturing is very energy- intensive, a product that lasts longer or requires less maintenance usually saves energy. Durable products also contribute less to our solid waste problems. 

Post Frame Buildings

Steel roofing is a more durable product with lower life-cycle costs than most other roofing systems available. The use of steel roofing reduces the amount of shingles and other roofing system materials going into our landfills. When used as a re-roofing option, steel can often be installed over the original roof, saving removal and disposal costs. Steel roofing and siding is also recyclable at the end of its useful life.

Choose low-maintenance building materials

Where possible, select building materials that require little maintenance (painting, retreatment, waterproofing, etc). Post Frame Buildings typically use steel trim and siding requiring little or low maintenance.

When used as an interior finish on walls and ceilings steel provides a durable, low maintenance finish for commercial, industrial and agricultural applications.

Use building products made from recycled materials

Building products made from recycled materials reduce solid waste problems, cut energy consumption in manufacturing, and save on natural resource use.

Post Frame Buildings “Steel is the world’s most recycled material. In the United States alone, nearly 70 million tons of steel were recycled in 2000. Every ton of steel that is recycled saves 2500 pounds of iron ore, 1400 pounds of coal and 120 pounds of limestone. New steel made with recycled content uses as little as 26% of the amount of energy that would be required to make steel from raw materials extracted from nature.” Per Bill Croucher, P.E. Director- Engineering of Fabral/Euramax, “The steel we buy from the mills is made by the Basic Oxygen Furnace process so it has an average recycled content of 31.7% which is 20.4% Post-Consumer recycled material and 9.6% Post-Industrial.”

Seek responsible wood supplies

Use lumber from independently certified well-managed forests. Avoid lumber products produced from old growth timber unless they are certified. Post Frame Buildings use renewable resource Southern Pine and Spruce-Pine- Fir lumber as the primary structural framework throughout the building. Lumber from sustainable and renewable forestry resources provide a more environmentally friendly source of constructions materials than old growth timber resources.

“Sustainable forestry means managing timberlands and their various resources to meet the needs of present generations without compromising the ability of future generations to meet theirs. It also means following a land stewardship ethic that integrates timber harvesting for useful products with conservation of soil, air, and maintenance of water quality and wildlife and fish habitat”(5) Although it is difficult to verify which forests all purchased lumber comes from due to the purchasing of large quantities of lumber from multiple brokers who in turn purchase from various lumber mills, lumber used in Cleary buildings is certified in part to various forestry management standards such as the Sustainable Forestry Initiative Standard (SFIS), the Forest Stewardship Council Standard (FSC) , and ISO 14001 environmental management system certification
