Smart board siding, also known as engineered wood siding, is very durable against rot, insects, and weather. It is also highly resistant to warping while retaining its ability to be easily painted.
Some smart board siding vendors augment the durability of their products by offering warranties in the event that the product does not live up to the claims made by the company. According to BobVila.com, the smart board siding industry has suffered from a number of class-action lawsuits having to do with moisture-related issues. These issues typically center on older siding products susceptible to moisture. In some cases, the issues arise from errors in product installation as well as product imperfections.
Such failures to install siding correctly may result in moisture invasion and mold and rot within both the structural supports and the sheathing. One reason why installation errors are likelier is that smart board siding products such as fiber cement weigh more than traditional wood does and they require special tools for cutting them.
If installed properly, smart board siding is a very durable product that is also very affordable because the materials themselves cost less than traditional wood and require little maintenance. Additionally, such siding can hold paint up to three times longer than wood, meaning less upkeep for the homeowner.
