Keeping Screws Tight

 · Thermal cycling poses two additional mechanisms for loosening. One is through annealing-heating and cooling the fastener to the extent that the strength it received from heat-treatment diminishes. The other is through expansion and contraction, which, like vibration, causes relative motion between the threads.

Reason Foam Fails #5: Excessive Shrinkage

The coefficient of thermal expansion/contraction for polyurethane foam is approximately a 1/4" gap for an 96" long foam board. A quarter of an inch gap in an airbarrier system is a massive hole, and such gaps/cracks can significantly degrade the thermal insulating value of the system. (Better tape those seams with something good!) Mind the gap!

Vinyl Plank Buckling

One of the major causes of buckling in vinyl plank flooring is expansion and contraction of the material. As the material becomes warmer, it can expand slightly, causing the floor to buckle. In the colder weather, the opposite is true and the floor can contract, leaving gaps between two of the tiles.
