Volume 3: Comparisons and Buying Decisions
Insulated vs Uninsulated Metal Building: What Pays Off in Oregon?
An insulated vs uninsulated metal building comes down to use: uninsulated is fine for basic storage, and insulation pays off once people work in the building or you need to control condensation.
When uninsulated can work
Equipment, hay or other low-touch storage where nobody spends much time inside. It costs less and installs faster.
When to insulate
Shops, workspaces, hobby areas and business space. Insulation:
- Makes the building more comfortable in cold mornings and hot afternoons
- Reduces condensation, which forms when warm, moist air meets cold metal. The Metal Building Manufacturers Association (MBMA) describes both visible condensation on surfaces and concealed condensation inside the wall and roof assemblies, which can corrode components and reduce insulation performance
- Cuts noise from rain and hail on the roof panels
- Makes the building easier to heat and cool, and more useful if your needs change
Do it correctly
Insulation only controls condensation if it is installed with a continuous, sealed vapor retarder, placed on the interior side in most climates. Gaps defeat the purpose. Ask your builder how the system will be sealed, and plan ventilation as well, especially if vehicles or livestock add moisture.
CC Steel installs both standard insulation and R-Boost in-house. See steel shops.
Decide by use
If the building is a shell for storage, you may not need it. If people will work, repair or spend time inside, insulate.
