Installing fiber cement lap siding is a common choice for homeowners and builders due to its durability and low maintenance. However, when it comes to attaching this siding, the debate between nails and screws is a critical consideration. In this article, we will provide clear and concise technical information about the use of nails and screws for fiber cement lap siding, making it accessible to both technical and non-technical audiences.
Fiber Cement Lap Siding
Fiber cement lap siding is a composite material known for its strength and resistance to moisture and pests. Its installation requires secure fastening methods that can withstand the test of time.
Nails for Fiber Cement Lap Siding
When using nails for fiber cement lap siding, consider the following technical details:
-
Nail Type: Corrosion-resistant nails, such as hot-dipped galvanized or stainless steel, are essential for fiber cement siding. These materials ensure the nails won’t rust over time.
-
Nail Length: The length of the nail is crucial. It should be long enough to penetrate the siding, the sheathing, and the underlying studs. For typical 5/16-inch fiber cement lap siding, 1.25 to 2-inch nails are appropriate.
-
Nail Shank: Opt for ring-shank or spiral-shank nails. These shanks provide superior holding power, preventing the nails from backing out over time.
-
Nail Head: A large, flat head is recommended. It helps secure the siding firmly and prevents it from pulling away from the structure.
Screws for Fiber Cement Lap Siding
When considering screws for fiber cement lap siding, keep the following technical details in mind:
-
Screw Type: Stainless steel or coated screws are ideal for fiber cement siding. These materials offer excellent corrosion resistance.
-
Screw Length: Similar to nails, the length of screws should be adequate to pass through the siding, sheathing, and studs. For 5/16-inch fiber cement lap siding, use screws that are 1.5 to 2 inches long.
-
Screw Thread: Opt for screws with aggressive threads designed for wood framing. This ensures a secure grip.
Installation Method
Whether you choose nails or screws, the installation method remains consistent:
-
Position the fastener at the top edge of the siding’s nailing flange.
-
Fasten the siding to the sheathing and studs at each stud location, typically every 16 inches.
-
Maintain a small gap between siding pieces to allow for expansion.
-
Ensure the fasteners are driven flush with the surface to achieve a smooth finish.
Conclusion
In the debate between nails and screws for attaching fiber cement lap siding, both options can be effective when the correct materials and installation methods are employed. Nails and screws provide a secure hold for siding, ensuring it remains in place and withstands the elements.
Choosing between nails or screws often depends on personal preference and the tools available. Regardless of your choice, it’s essential to understand the technical details related to nail type, length, shank, and head, as well as screw type, length, and thread.
By adhering to these guidelines, you can ensure a durable and visually appealing installation of your fiber cement lap siding, regardless of your level of technical expertise.
