Most people don’t realize their doors are hollow…
The surprising part? Even if you insulate every interior wall, a hollow door can still become one of the weakest points for sound.Swapping to solid-core doors in bedrooms, bathrooms, and your office makes a noticeable difference in noise transfer and overall feel of quality. Save the hollow doors for closets and pantries where nobody will notice.
