Which siding is known for its vulnerability to weathering?

Wood siding is known for its vulnerability to weathering due to its organic composition. Over time, wood is susceptible to various environmental factors such as moisture, UV radiation from sunlight, and temperature fluctuations. These elements can lead to issues like rot, mold, and decay, significantly impacting the integrity and appearance of the siding. Additionally, wood can warp or crack as it expands and contracts in response to changing weather conditions. Although treatments and sealants can mitigate some of these vulnerabilities, wood siding generally requires more maintenance than other materials to maintain its durability and aesthetics in the face of weathering.
