What material may allow air drafts, rattling, and water penetration if in poor condition?

The correct material that may allow air drafts, rattling, and water penetration if in poor condition is putty. Putty is typically used to seal gaps, particularly around windows and sometimes doors, where it accommodates changes in temperature and may shrink or crack over time. When putty deteriorates, it loses its effectiveness to seal these areas, leading to potential air leaks and allowing water to penetrate. This can cause increased energy costs due to drafts and may lead to further damage from moisture infiltration.

In comparison, caulking and sealants are usually more flexible and specifically designed for modern applications where long-lasting watertight seals are necessary. They tend to adhere better and maintain their sealing properties longer than putty, reducing the likelihood of gaps forming. Plaster, while used for interior walls, serves a different purpose and does not function primarily as a sealant for drafts or water penetration like putty does. Thus, when assessing issues related to drafts and water infiltration, putty's degradation is particularly critical.
