True or False: All wood used in construction must be treated for rot prevention.

The assertion that all wood used in construction must be treated for rot prevention is false because not every application requires treated wood. Pressure-treated wood is necessary for certain environments and conditions, especially those where the wood will be in direct contact with soil or exposed to moisture, such as decks, posts, or fencing, where the risk of decay and insect infestations is high.

However, there are applications where untreated wood is perfectly acceptable, especially in controlled environments where the wood is protected from moisture and pathogens, such as indoor framing or cabinetry. Various wood species, like cedar or redwood, also possess natural resistance to rot without the need for chemical treatment. This diversity in wood usage allows builders to choose materials based on the specific needs of a project and the environmental conditions they will face, leading to the conclusion that not all wood requires treatment for rot prevention.
