Definition - What does Weather Resistance mean?
Weather resistance is the ability of a material to prevent corrosion, loss of material or any sort of deterioration due to prolonged exposure to harsh environmental and weather conditions. Harsh environmental and weather conditions include an acidic atmosphere with high temperature, pollution, humidity, strong sunlight, wind, moisture, snow or extreme temperature conditions.
Corrosionpedia explains Weather Resistance
Some climates are harsher than others and present unique challenges. Therefore, industrial, commercial and residential structures and their construction materials, paints and coatings must be selected in a way that can tolerate the adverse and harsh climate conditions.
For example, siding materials can provide continued protection against high wind by containing sturdy material. The fabric might also be able to withstand colder temperatures than other forms of siding. Some areas have high temperatures and high humidity; this climate will result in issues with mold development and deterioration, which may severely damage a building's structure.
An example of good weather resistance is the paint applications performed on automobiles that protect the sheet metal from harmful environmental conditions.
