How can the longevity of masonry veneer be affected by weather conditions?

Extreme temperatures can lead to cracking in masonry veneer for several key reasons. When temperatures drop significantly, the moisture that infiltrates the veneer can freeze. This freezing causes the water to expand, which puts tremendous pressure on the masonry materials. If the temperature fluctuates between freezing and thawing, this cycle can exacerbate the cracking further, leading to structural integrity issues over time.

During extreme heat, the materials can become overly dry, which can also contribute to cracking as the materials contract. This means that both very high and very low temperatures can negatively impact the longevity of masonry veneer.

Understanding the influence of weather conditions on masonry is critical for contractors and builders because it helps them choose appropriate materials and methods to ensure durability in different climates, particularly in areas where temperature extremes are common.
