Hardened wood also can support sustainability goals. Its production process maximizes yield, using less raw timber per plank and producing more flooring from the same amount of material. This efficient resource use can contribute to environmental certifications and broader sustainability targets. GUIDELINES FOR A SUCCESSFUL INSTALLATION Installation is just as important as the type of material you select. To create a living environment that is set up for long-term success there are some key guidelines that should be followed when adding hardened wood to a multifamily space.

Manage moisture: Always use an appropriate moisture retarder, especially over concrete slabs, crawlspaces, or radiant-heated floors. Control environmental conditions: Indoor temperature should remain between 60-80°F, and relative humidity should stay between 30 to 50 percent before, during, and after installation. Leave a perimeter gap: Wood needs room to expand and contract with seasonal changes. A proper expansion gap prevents issues later on. Failing to address any of these factors can lead to movement, noise, or even damage over time, issues that are common in high-occupancy buildings. FLOORING FOR THE LONG TERM Ultimately, the look of hardwood adds timeless character to any multifamily space, but ensuring tenant comfort demands more than just visual appeal. Hardened wood strikes a balance between classic aesthetics and advanced performance by providing long-term strength, sound mitigation, and resource efficiency.

Ensure subfloor flatness: Subfloors should be no more than 3/16” out of plane over a 10’ radius, or 1/8” over a 6’ radius.
