This will reduce the dew point temperature to 37 degrees limiting the frequency of the problem. The combination of proper roof ventilation, tight construction and low indoor humidity levels will help minimize the chance this problem will occur. Floor boards squeak as homeowners walk across the floor. Squeaky floors rank high in nuisance value. Customers usually hold their complaints until the squeak has exploded their nerve endings, placing the attempted fix under the closest scrutiny.
Squeaks result from wood rubbing against wood.
But effecting that theory may be difficult. A common source of noise arises when a floor joist shrinks after it is installed. A space develops between the subfloor and the top of the floor joist. When a homeowner walks over this spot, the subfloor moves against the joist and squeaks. If squeaks are located in the first floor, you're in luck.
