Floor Options FAQ

Common Questions Before You Choose

Why is pricing shown per square foot?
Floor upgrades scale with building size. Per-square-foot pricing prevents misleading flat rates across different shed footprints.
Which upgrades are best for workshops?
Stronger joist spacing (12" O.C.) and heavier-duty plywood layers are essential for supporting heavy equipment and tools.
When should I insulate my floor?
Insulated floor systems make the most sense for comfort-oriented buildings like home offices, studios, or seasonal workspaces.
