Windows and window placement on a post frame building

Choosing windows for your post frame building is an important component to get right. Windows are an essential part of almost any construction. Not only do they provide visibility to the surroundings, but they also serve to lower energy costs by providing natural light. Modern energy-reducing windows can also limit the transfer of energy to the exterior.

Whether designing a new post frame construction or looking to renovate an existing structure, window type and placement are important considerations. Your design objectives should be to create a window design that fosters energy efficiency while highlighting the style and purpose of your post frame building.

It is always best to work with a post frame design expert when planning a new post frame construction or remodel. Keep the following considerations in mind when choosing windows and window placement for your post frame building.

Orientation of Your Post Frame Building

The amount of natural light that could enter your post frame structure depends on the direction the building faces. While other factors, such as ease of access, might play a more significant role in this determination, having larger properly positioned south-facing windows provides maximum natural exposure during the day. It is necessary to plan the placement so that the contents of the building will not block the sunlight entering the building.

Window Styles and Grids

Post frame construction allows for the same standard window styles as other building methods. These include:

  • Single-hung windows
  • Double-hung windows
  • Casement windows
  • Horizontal Sliding windows

However, post frame building owners are not limited to these “basic” window types. You may also choose more stylish, aesthetically pleasing options such as Colonial Casement, Half-Round, Gothic, Full Circle, Oval, Pentagon, Trapezoid, Triangle, and more. Your post frame design specialist can help you decide what will work best for your project and aesthetic

Glass Options

In almost any post frame window setting, tempered glass is the best choice, particularly for barns, workshops, equestrian centers, and other places where equipment, animals, and materials are frequently moved and stored.

Where the chances of impact are minimal, double-paned insulated glass is best for keeping energy from escaping and maintaining comfortable temperatures.

Low-emissivity or “Low-E” glass products reduce energy loss by 30% to 50%. While these are about 10% to 15% more expensive, the energy savings will quickly outstrip the additional cost.

For post frame renovations, adding or replacing existing windows with modern, energy-saving windows will enhance the structure’s appearance. Most importantly perhaps, these installations will immediately begin paying back those renovation costs in energy savings and comfort.


Placing skylights can provide plenty of light without impacting how to arrange the building’s contents. Note, the roofing material must be able to accommodate these window openings.

Additionally, skylights in some climates will require substantial reinforcement. Especially in areas where excessive ice and snow are likely.
