By carlye jones rippling in a wood floor is called chatter if the ripples are less than 1 1 2 inches apart and waves if the ripples are more than 1 1 2 inches apart.
Should wood floor feel like it has waves.
From the statement you make sometimes it is worse than other times i would guess conditions are not consistent throughout the year.
If they do not have rotary sanders like a trio or power drive.
The boards are not laying completely flat.
Since this doesn t allow a small air gap between the wood floor and the subfloor this option eliminates that hollow sound and it makes engineered wood feel and sound like real hardwood.
They need to spend a lot of time on the finish sanding.
The walls and windows that surround a wood floor are also partly responsible for room echo.
Either way the result is not.
The waves can be fixed but floors will need complete rework.
They have a wavy like appearance and you can feel the waves with your hands.
I noticed the waves on hardwood floor probably a month or so after installation.
Sound waves bounce between the wood floor and the walls intensifying the effect.
If you want to go with this option just keep in mind that any glue that seeps through the seams must be cleaned up immediately and it can have an odor.
They can use a multi disc driver plate.
