New construction barndominium insulation in Walling TN completed by Koala Insulation of Upper Cumberland. A lot of new barndominium owners want one thing once the structure is up: make sure the inside performs as well as the outside looks. That was the focus on this new build in Walling, Tennessee. The home was built by Summertown Metals, and once the shell was ready, the next decision was how to insulate it in a way that matched the homeowner’s goals, the layout of the building, and the available budget.

At Koala Insulation of Upper Cumberland, we installed spray cellulose in the wall cavities and used batt insulation in the ceiling areas and in the parting wall between the garage and living space where spray application was not the best fit.

Why Spray Cellulose Was Chosen

This homeowner specifically wanted spray cellulose because it gives strong coverage while staying budget-conscious. Spray cellulose settles densely into wall cavities, which helps reduce open air movement and creates a tighter thermal layer than many owners expect. In a barndominium, that matters because large, framed sections can lose performance quickly if insulation leaves gaps. One reason we often recommend spray cellulose in projects like this is density. It fills irregular areas well, presses into corners, and creates better contact across framing surfaces, which helps improve air sealing.

Why Batt Insulation Was Used in Certain Areas

Not every section of a home calls for the exact same insulation method. In this Walling project, batt insulation made more sense in the ceiling sections and in the parting wall between the garage and living space where spray cellulose was not practical for installation. That combination allowed the homeowner to stay within budget while still insulating each area based on how the structure was built.

Why Insulation Choices Matter in a Barndominium

Barndominiums often have larger open spaces, taller ceilings, and framing details that behave differently than traditional homes. That means insulation choices should be made carefully during construction, not after problems show up later. According to U.S. Department of Energy, proper insulation helps reduce unwanted heat flow and improves year round indoor comfort, especially in newly built homes where envelope performance can be planned early. The advantage during new construction is that insulation can be matched to the exact design before drywall closes everything in.

Built to Match the Homeowner’s Priorities

This project was not about choosing one product everywhere. It was about using the right insulation in the right places. The homeowner wanted solid performance, good air sealing, and a reasonable budget. Spray cellulose gave the wall system the dense coverage they were after, while batt insulation handled the sections where spray application was less practical.
