Before discussing their necessity, let’s first understand what starter strips are. Starter strips, also known as J-channels or starter courses, are typically made of aluminum or vinyl and are used to secure the first row of siding at the bottom of the wall. The purpose of using starter strips is to create a level and straight starting point for the fiber cement siding panels.
Providing a Level Foundation
One of the primary reasons starter strips are necessary for fiber cement siding installation is that they provide a level foundation for the first row of panels. Without starter strips, it can be challenging to achieve a straight and even alignment of the siding. Uneven or crooked siding not only affects the visual appeal but can also compromise the performance and durability of the siding.
Preventing Moisture Infiltration
Another important function of starter strips is to create a barrier against moisture infiltration. The bottom edge of the fiber cement siding panels should not come into direct contact with the surface it is mounted on. Starter strips provide a slight gap between the siding and the surface, preventing water from seeping into the backside of the panels. This helps to protect the structural integrity of the siding and prolong its lifespan.
Ensuring Proper Ventilation
Proper ventilation is crucial for maintaining the health and longevity of any siding material, including fiber cement. Starter strips allow for an adequate airflow between the bottom of the siding and the underlying layer. This helps to prevent any moisture buildup that can lead to mold, rot, or other moisture-related issues. The ventilation provided by starter strips also helps to regulate the temperature inside the wall, reducing the risk of condensation.
Simplifying Installation
Using starter strips in the installation of fiber cement siding also simplifies the process for both homeowners and contractors. These strips act as a guide or template for ensuring that the first row of siding is installed straight and level. They provide a clear reference point and help eliminate guesswork, resulting in a more efficient and professional installation.
Improved Aesthetics
Lastly, but certainly not least, starter strips contribute to the overall aesthetics of the fiber cement siding. By creating a neat and evenly aligned starting point, starter strips ensure a smooth transition between rows. This clean appearance enhances the curb appeal of the property and provides a professional finish to the siding installation.
Final Thoughts
While some may consider starter strips as an added expense or an unnecessary step in the fiber cement siding installation process, their importance should not be underestimated. Starter strips provide a level foundation, prevent moisture infiltration, ensure proper ventilation, simplify installation, and enhance the overall aesthetics of the siding. Considering these benefits, using starter strips is highly recommended for a successful and long-lasting fiber cement siding installation.
