Understanding Azek Trim: What Makes It Durable and Repairable?
How Azek Trim Compares to Wood and Engineered Wood Trim
Azek trim is produced using cellular PVC, which is a plastic trim material that is used as exterior trim. Nevertheless, Azek is also more durable by default since it does not rot, shrink or attract termites, as opposed to the traditional wood or engineered wood trim. Wood trim takes in moisture and is likely to crack as it swells and contracts due to weather changes. Wood is better but may still disintegrate due to ensuing moisture.
Since Azek is non-porous and stable, it will resist a great number of typical reasons for wood trim failures. Stability also implies that the repairs are usually done by filling and refinishing instead of replacing the areas that have decayed.
Benefits of Choosing Azek Trim for Long-Term Durability
Azek trim is not affected by moisture, insect damage, and decay, thus minimizing the maintenance work and the number of repairs done. It also incorporates its color in the trim board, therefore, when it becomes scratched or dented, one cannot see the other cores of varying colors. Also, the Azek boards can be finished or painted, which allows them to be more flexible when it comes to appearance and maintenance.
Azek trim products are a good investment in curb appeal when properly installed and maintained in due course; they should last decades.
Common Causes of Damage to Azek Trim Products
Exposure to Extreme Weather Conditions
Azek trim is resistant to moisture, but at extreme temperatures of either cold or heat, some expansion and contraction may occur. The material can be stressed due to rapid temperature changes, causing minor cracking. Dents or chips may be brought about by high winds or hailstorms.
Physical Impact and Accidental Damage
Azek trim may crack or break down due to accidental impact of a trimming or landscaping tool, ladders, or even children playing on the wall. Azek is not as hard as wood, but it cannot resist physical damage.
UV Fading and Discoloration Over Time
Unfinished Azek trim can be faded by direct sunlight and can also chalk on the surface. This is a cosmetic weathering effect, which may harm the look and thus needs to be refinished or repainted to recover appearance.
