Flooring squeaks and "pops" are typically the result
of the interplay between the tongue and groove in adjacent rows of
Tongue and groove material rubs together during facility
use, causing squeaking and popping sounds during either the loading
phases of activity on the surface.
Maple flooring is
a hygroscopic material. When exposed to varying temperatures
and humidities, it will release or absorb moisture
until it is at equilibrium with the surrounding atmosphere.
This environmental interaction will cause individual
flooring strips to expand or contract.
flooring system movement combined with facility use
at certain times during the year can result in the development
of squeaks and "pops" in scattered locations when the match between
tongue and groove in adjacent strips changes.
impossible to guarantee that any wood floor system
will not develop squeaks or "pops" as a result of normal seasonal expansion
and contraction. Due to resiliency requirements and multi-layer subfloor
configurations, some systems tend to develop squeaks and "pops" more
consistently at certain times of the year than other
systems. Expansion/contraction cycles and resulting
squeaking/popping difficulties can be minimized
by maintaining a consistent indoor environment.
Maple Flooring Manufacturers Association (MFMA) recommends
maintaining air temperatures between 55 and 75 degrees,
and indoor relative humidities between 35 and 50 percent year round.
If flooring materials are properly
acclimated, a 15 percent fluctuation in indoor relative
humidity will not adversely affect the maple. Excessive
shrinkage and/or expansion
(and resulting squeaks/pops) may develop with indoor
relative humidity variations in excess of 15 percent.
for noisy floors include the application of talcum
powder in areas of occasional squeaks or pops, or the
installation of additional
mechanical fasteners (face-applied and plugged) in
areas of persistent squeaks. The latter remedy may
not be an option on certain floating
