Trivia: What problem does weatherstripping solve?
The correct answer is Air leaks
So why is this answer correct? : Air leaks can cause drafts and excess moisture around movable home components like doors and windows. Because they can’t be sealed permanently, a felt, foam, or vinyl strip is attached to the doorway or window frame to help close the gap and eliminate air leaks. Fixing these issues with weatherstripping also saves homeowners money on utilities by cutting down on heating and air conditioning costs.
