Is underlayment necessary for nailed down engineered hardwood floors?

If you want your engineered wood floor to last a long time, you need an even subfloor. Underlays smooth out the subfloor and cancel out minor dips and flaws that might otherwise affect your new floors. The even surface an underlay provides creates more stability for your engineered wood floors.

Is it better to use OSB or plywood for subfloor?

OSB has a lower resale value than plywood due to its lower strength. For this reason, few homeowners prefer OSB in their homes. Apart from costs, plywood is superior in all the other areas, such as the strength of the structure. For this reason, it’s a superior material for use on the subfloor.

What thickness subfloor is recommended?

The spacing of the joists governs the recommended thickness of the plywood subfloor. Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but you should use slightly thicker 3/4-inch plywood for joists spaced further apart.

On the four foot edges, your seams will fall on joist tops, so no need for tongue and groove. But to start off, we will need to remove the tongue so the plywood is tight with the exterior ICF walls.

Does engineered floor need expansion gap?

Although engineered hardwood floors can withstand changes in temperature and moisture better than solid wood floors, they still need an expansion gap to allow for small movements.
