What is it?

A type of building material used as exterior cladding for homes and buildings. It is made from a mixture of cement, sand, and cellulose fibers.  Formed under pressure to the required profile that is strong, durable, and low-maintenance.

Designed to last for many years with proper maintenance and can last up to 50 years or more. The lifespan of fiber cement siding is largely dependent on factors such as the quality of the material, proper installation, and the severity of the climate and weather conditions. For example, in regions with harsh climates and extreme temperature fluctuations, the siding may have a shorter lifespan compared to areas with milder climates.

Proper maintenance, such as regular cleaning and painting, can extend the lifespan of the product. Additionally, using high-quality paint and caulking to protect against water damage and other elements can also help prolong its lifespan..

In conclusion, fiber cement siding is a durable and long-lasting option for exterior cladding that can last up to 50 years or more with proper maintenance and protection from the elements.
