A Wood garage floor is a viable solution.
We often get a surprised look when we tell customers our garages have wooden floors. It is understandable because it is not something many are accustom to. Wood is very strong when it is used correctly.
We don’t skimp on the number of joists we use. The joists are placed every 8 inches. That limits the stress on the sub straight from spanning too large of a gap. The sub straight is 3/4″ tongue and groove Huber PerformMax® 500 flooring.
“PerformMAX 500 is thermally fused to the panel during the manufacturing process, providing a 100% bond that will not peel or delaminate during use even if subjected to moisture or mechanical pressure.”

Wood garage floors are cost-effective.
We can build our garages as floorless models that can be placed on a concrete slab or footing. While being very strong, concrete is costly. The option of an engineer wood floor system makes owning a garage a possibility for many.
We have sold hundreds of garages with our wood floor with great success, and we stand behind our products.
