Designing the Interior of Your Barndominium: Drywall, HVAC, and Insulation Tips
The frame is up and the siding is on. You officially have a building, but it is not yet a home. Designing a comfortable barndominium interior requires shifting your focus from structural assembly to systems and finishes.
This phase is where your project transforms from a barn into a living space. While the exterior of our DIY barndominium kits gives you that rugged aesthetic, the interior framing is built with standard lumber. This is a massive advantage for you. It means you can use the same insulation, drywall, and finishing techniques found in a traditional house. We will guide you through the critical steps of closing up your walls and controlling your climate.
Key Takeaways
- Standard Framing: Best Barns kits use standard 2x4 wall studs spaced 16 inches or 24 inches on center, making them compatible with standard fiberglass insulation batts.
- Ventilation is Vital: You must install soffit vents and ridge vents to ensure proper air circulation between your insulation and the roof sheathing.
- HVAC Zoning: Two-story models like the Colossal often require separate heating and cooling zones or mini-split systems to keep the upstairs loft comfortable.
- Drywall Simplicity: Unlike steel-framed buildings, you can screw drywall directly into the wood studs of these kits without needing extra furring strips.
- Utility Rough-in: Always run your electrical wiring and plumbing pipes through the wall cavities before you close them up with insulation and drywall.
How Do You Insulate a Wood-Framed Barndominium?
Insulation keeps your home warm in winter and cool in summer. Because Best Barns kits use TimberPrestige™ wood framing with defined stud cavities, you have several easy options.
Fiberglass Batts: This is the most common DIY choice. You buy rolls of fiberglass insulation sized for 2x4 walls. You simply staple the paper facing to the studs.
- Wall Fit: The manuals show stud spacing is typically 16 inches or 24 inches on center. You can buy batts pre-cut to these exact widths.
Spray Foam: Spray foam offers a superior air seal and higher R-value per inch. It fills every gap in the wall cavity. It is more expensive, but it adds structural rigidity and blocks moisture effectively.
The Importance of Ventilation: You must let your roof breathe. If you pack insulation tight against the roof sheathing without airflow, you will get mold.
- Soffit Vents: You need to install vents in the soffit (the underside of the roof overhang) to let fresh air enter.
- Ridge Vents: You should leave a 1-inch gap at the peak of the roof sheathing to allow hot air to escape through a ridge vent.
- Baffles: Install foam baffles between the trusses to create a channel for air to flow from the soffit to the ridge.
What Are Your Drywall and Wall Finish Options?
This is where the difference between metal and wood kits becomes obvious. In a metal building, you often have to build a separate wood frame inside the metal shell just to hang drywall. In a Best Barns kit, the structure is the frame.
Hanging Drywall
ou can screw drywall sheets directly to the wall studs and ceiling trusses.
- Blocking: If you plan to hang heavy cabinets or a TV mount, install extra 2x4 "blocking" between the studs before you put up the drywall. The kit often includes spare lumber or cut-offs you can use for this.
Wood Paneling
For a true rustic look, many owners skip drywall and install tongue-and-groove pine boards or shiplap directly to the studs. This is durable and fits the "barn" aesthetic perfectly.
Interior Partitions
The kit provides the exterior shell. You frame the interior rooms yourself using standard lumber. This allows you to place the bathroom and bedroom walls exactly where you want them to create your layout.
How Should You Handle HVAC in a Barndominium?
Barndominiums often feature high ceilings and open lofts, especially in the Colossal series. This makes heating and cooling tricky.
The Stack Effect: Heat rises. Your second-story loft will be much hotter than your ground floor.
- Solution: Use a ceiling fan to push warm air down in winter. For cooling, install a return air vent at the highest point of the ceiling to pull hot air out.
Mini-Split Systems
Ductless mini-splits are fantastic for barndominiums. You can put one unit in the main living area and a separate unit in the loft bedroom. This allows you to control the temperature of each zone independently, saving money on your electric bill.
Central Air
f you prefer a traditional ducted system, you will need to run ductwork through the floor trusses between the first and second levels. You must plan this "chase" or path for the ducts before you install the loft flooring.
What Comes First: Utilities or Insulation?
You must follow the correct order of operations to avoid ripping open your walls later. By following this sequence, you ensure that your pipes are protected within the insulated envelope of the house, preventing them from freezing in winter.
- Rough Framing: Build all your interior partition walls.
- Rough-In Utilities: Run all electrical wire, plumbing pipes, and HVAC ducts through the studs and floor joists.
- Inspections: Have your local inspector approve the wiring and plumbing.
- Insulation: Fill the wall cavities only after the wires and pipes are in place.
- Walls: Install your drywall or paneling to close up the structure.

Frequently Asked Questions
Can I install drywall directly on the studs?
Yes, Best Barns kits use standard wood studs, so you can screw drywall directly to the framing without needing furring strips.
Do I need a vapor barrier?
Yes, in most climates you need a vapor barrier on the warm side of the insulation (usually behind the drywall) to prevent moisture buildup.
How do I heat a high-ceiling barndominium?
Radiant floor heating is very effective for high ceilings as it heats objects near the floor, or use ceiling fans to circulate warm air.
Can I run plumbing in the exterior walls?
Avoid running water pipes in exterior walls if you live in a cold climate, as they can freeze. Keep plumbing in interior walls when possible.
What is the best lighting for a barn interior?
Recessed "can" lights are excellent for general lighting in lofts with low clearance, while large pendants work well in open, high-ceiling areas.
