Bi-Fold Door Example

Here’s an example of a bi-fold door. While commonly seen on aircraft hangar buildings, these doors are favored by owners needing extensive access. This photo from a windmill manufacturing building highlights the door’s versatility, emphasizing that it’s no longer limited to hangar use.

Although primarily added for aesthetics, cupolas contribute architectural intricacy to a building’s roofline. These square roof additions are particularly favored in agricultural, barn, and barndominium projects.

Walk Door Overhangs

The 1 to 4-foot overhangs not only enhance the entrance’s visual appeal but also offer practical benefits. Door overhangs assist in keeping doorways and handles cool during summer and ensure entrances stay clear of snow in winter.

Interior Components Demonstration

Several exterior components, like wall lights, vents, and doors, significantly impact the functionality of the building’s interior. Adding wall lights, as depicted below, notably enhances the influx of natural light indoors.

Roll Up vs Sectional Doors

Roll-up doors and sectional doors come in identical sizes but offer distinct advantages. In the image, roll-up doors coil into a canister, minimizing overhead interior space compared to sectional doors. Sectional doors slide along a track, akin to residential garage doors. The advantage of sectional doors is their suitability for shorter buildings, unlike roll-up doors, which require an additional foot of height to the building’s eave—heightening the building can incur added costs.
