Pick for Stability and Quiet
Attics see wider thermal swings and are often above living areas, so select stable, quiet systems. Engineered hardwood with multi-ply cores offers real-wood warmth and good dimensional stability. Luxury vinyl plank (LVP) handles humidity shifts and resists dents—great for family spaces. Cork adds natural thermal and acoustic comfort; high-density options resist compression. For workrooms, commercial-grade carpet tiles with cushion back reduce footfall noise and are easy to replace.
Underlayment & Acoustics
Use tested acoustic underlayments (Delta IIC/STC ratings) to tame footfall. Float systems where appropriate, but follow manufacturer limits on room size and transitions to avoid buckling. Seal perimeters at knee walls and penetrations to preserve the air barrier.
Radiant & HVAC Compatibility
If adding radiant heat, confirm max surface temperatures and R-value limits for your floor. Many engineered woods and LVPs are radiant-compatible; avoid thick pads that insulate against heat. Leave expansion gaps and acclimate materials in conditioned space before install.
Stairs & Thresholds
Use flush transitions at stair landings to keep nosings code-safe, and specify stair treads that visually coordinate with the attic floor for a seamless look.
