How does laminate flooring compare to LVP for noise transmission between floors in a NB two-storey home?

LVP with quality underlayment significantly outperforms laminate for noise reduction between floors, making it the better choice for NB two-storey homes where sound transmission is a concern.

The key difference lies in the core materials and how they handle impact sound. Laminate flooring uses a high-density fiberboard (HDF) core that's rigid and transmits footstep vibrations directly through the subfloor to the ceiling below. Every heel strike, dropped toy, or chair scrape travels through the hard surface with minimal dampening. LVP, particularly products with WPC (wood plastic composite) or SPC (stone plastic composite) cores, has inherent flexibility that absorbs some impact energy before it reaches the subfloor.

Underlayment makes the critical difference for both products, but especially for laminate. A quality acoustic underlayment with sound-dampening properties can improve noise reduction by 15-25 decibels for laminate installations. Cork underlayment ($1.00-$2.00/sq ft) provides excellent sound absorption, while specialized acoustic foam with vapor barriers ($0.75-$1.50/sq ft) offers good performance at a lower cost. Many premium LVP products come with pre-attached acoustic backing, eliminating the need for separate underlayment while providing superior sound control compared to laminate.

In NB's older housing stock, this becomes especially important. Many pre-1980s homes have traditional joist and subfloor construction with minimal sound insulation between floors. The Maritime climate's humidity swings can also cause subfloor movement that amplifies sound transmission through rigid flooring materials. LVP's dimensional stability in NB's 30-50% humidity swings means fewer seasonal gaps and squeaks that can develop with laminate installations over time.

For maximum noise reduction, consider these approaches: Install 6mm cork underlayment under laminate ($1.00-$2.00/sq ft additional cost), choose premium LVP with integrated acoustic backing (COREtec, Shaw Floorte Pro, or Mannington Adura Max), or add sound insulation in the floor cavity below during renovation. The investment in proper acoustic treatment pays dividends in family harmony, especially during NB's long winter months when everyone spends more time indoors.

Professional installation ensures proper underlayment coverage and seam sealing, which prevents sound leakage at edges and transitions. While both products are DIY-friendly, the acoustic performance depends heavily on continuous, gap-free underlayment installation that experienced flooring contractors execute more consistently than most homeowners.
