💡 What prevents squeaking and reduces impact noise under raised plank surfaces during heavy movement?
The crosslinked foundation works as a handy shock pad that absorbs sudden force waves.
- Each layer traps air pockets that stop vibration from traveling into concrete bases
- You get steadier footing and fewer rattling sounds when dragging furniture
- The thin setup also leaves enough clearance for door frames to swing smooth
