Is LP SmartSide Siding Waterproof?

By

When it comes to home siding, durability and low maintenance are key priorities. One material that checks both these boxes is LP SmartSide, a popular choice among homeowners. But a common question arises: is LP SmartSide waterproof?

Before delving into the specifics, it's essential to understand what 'waterproof' truly means in the context of home siding. Waterproof materials are those that don't allow any water to pass through, while water-resistant materials can withstand water for a certain duration but may eventuallyallow some penetration. So, let's explore the water resistance capabilities of LP SmartSide.

LP SmartSide's Engage Technology

LP SmartSide comes equipped with a unique 'Engage' technology that contributes significantly to its water-resistance capabilities. This technology combines a strong resin-binding system with enhanced zinc borate to create a robust, water-resistant siding material.

The 'Engage' technology is applied throughout the siding, which means there are no water-absorbing plywood seams or weak points, ensuring uniform water resistance. However, while LP SmartSide is indeed highly water resistant, it's crucial to note that it isn't entirely waterproof. Here's why:

Water Exposure and Drainage

When water is exposed to LP SmartSide, the 'Engage' technology helps prevent water absorption for an extended period. Yet, given enough time and consistent water exposure, some water may eventually penetrate—not because LP SmartSide is ineffective, but mainly due to the nature of water and its tendency to find weak points.

To mitigate this, professional LP SmartSide installation should always involve proper water drainage. Installers should ensure that water runs off the siding and away from the home, reducing the likelihood of prolonged water exposure. This proper installation technique is crucial to maximize the water resistance of LP SmartSide.

Proper Siding and Flashing Installation

Besides the water-resistance capabilities of LP SmartSide itself, proper installation plays a pivotal role in ensuring the exterior of your home remains dry. This includes installing flashing behind corners and around doors and windows—a crucial step that redirects water away from your home, protecting both your siding and your home's interior.

When installed correctly, LP SmartSide performs remarkably well in maintaining a dry, comfortable living space, even in humid or rainy climates. Remember, the best siding material is only as good as its installation. Therefore, always ensure you hire a professional installer with experience in LP SmartSide installation.

LP SmartSide's Durability and Maintenance

You might wonder why durability and low maintenance are crucial, even if LP SmartSide isn't entirely waterproof. The answer lies in the overall performance of the siding. LP SmartSide's durability and resistance to other elements, such as hail, wind, and termites, mean it continues to protect your home even in harsh conditions, reducing the need for frequent repairs and maintenance.

Moreover, this strength and durability contribute to LP SmartSide's consistent appearance over time, retaining its aesthetically pleasing look even with minimal upkeep. So, while water resistance is essential, it shouldn't be the sole factor in your siding choice. Instead, consider the material's all-around performance and how it aligns with your specific needs.

In the end, while LP SmartSide isn't perfectly waterproof, it's certainly water-resistant, making it a reliable choice for your home's exterior. With proper installation and regular maintenance, you can enjoy a durable, low-maintenance siding material that stands up to water, wind, and other elements. So, why not give LP SmartSide a try and experience its excellent performance firsthand? Just remember to hire a professional for the installation to ensure the best possible results.
