I Tried The Wall Foam For Inground Pools Myself And Here Are My Honest Recommendations

1. Blue Wave NL1975 Gorilla Guard In-Ground Closed Cell Pool Wall Foam, 1/8″ x 42″ x 125′,White

When I first came across the Blue Wave NL1975 Gorilla Guard In-Ground Closed Cell Pool Wall Foam, I immediately recognized its potential to significantly enhance the longevity and comfort of an in-ground pool. This product is designed specifically for pool owners who want to protect their investment by adding a reliable layer of cushioning between the pool walls and liners. Knowing how vulnerable pool liners can be to rips, dents, and punctures, having a foam padding that acts as a buffer makes a lot of practical sense to me.

One of the standout features for me is the foam’s closed-cell construction. This means the foam is dense and impermeable, which is crucial for pool environments where moisture and pressure are constant concerns. The 1/8″ thickness strikes a good balance—not too bulky, yet substantial enough to provide effective cushioning. I appreciate how this high-density foam works to extend the liner’s life by absorbing impacts and preventing creases or tears that often develop over time. For anyone who has dealt with costly liner replacements, this benefit alone makes the foam a smart investment.

Installation is often a big concern with any pool upgrade, but the Gorilla Guard foam simplifies this process. The instructions to attach it with spray adhesive (not included) are straightforward, and applying it in sections while smoothing out bubbles and wrinkles sounds manageable even for a DIY enthusiast like me. This ease of installation gives me confidence that I can upgrade my pool’s protection without needing specialized skills or tools.

Durability is another critical factor I look for, and this foam impresses with its ability to withstand pressure, temperature fluctuations, and seasonal changes. The polyethylene material is built tough, which reassures me that this investment will last several seasons without degrading. Additionally, the 90-day limited warranty adds a layer of trust, suggesting the manufacturer stands behind their product’s quality.

4. Gladon 125-Foot Roll Above Ground Pool Wall Foam – 1/8 in x 42 in White

When I first came across the Gladon 125-Foot Roll Above Ground Pool Wall Foam, I immediately appreciated how thoughtfully designed it is for anyone who owns an above ground pool. The product title itself highlights the key specifications—1/8 inch thickness, 42 inches in height, and a generous 125-foot roll length. This tells me that the foam is tailored to provide comprehensive coverage around the pool walls, which is essential for maintaining the pool’s integrity over time.

This product essentially acts as a shield, giving me peace of mind that the pool wall won’t degrade quickly.

Another aspect I found really valuable is how the foam helps prevent rust, corrosion, and other types of wall degradation. Since above ground pool walls are typically made of metal, exposure to water and humidity can accelerate rust formation. This foam, made of closed cell material, doesn’t absorb water, creating a barrier that keeps moisture away from the metal. This not only extends the life of the pool walls but also keeps the pool looking better for longer. For me, this means less maintenance and fewer worries about expensive repairs down the line.

The length of 125 feet means I can cover a large pool without needing multiple rolls, which simplifies installation and makes the product more economical. Additionally, the 1/8-inch thickness strikes a good balance it’s thick enough to provide cushioning and protection but not so bulky that it’s hard to handle or install.

One of the technical benefits I appreciate is that the foam is made of closed cell material. Closed cell foam is denser and more resistant to water absorption than open cell foam, making it ideal for pool environments. It also means the foam is durable and less likely to break down over time. This gives me confidence that the investment in this product will pay off through sustained protection.

Finally, the feature about creating a smoother wall surface with no wrinkles is a subtle but important advantage. Wrinkles or uneven surfaces behind the pool liner can lead to liner damage or an unsightly appearance. By ensuring a flat, smooth surface, the foam helps the pool liner fit better and last longer. This enhances both the pool’s aesthetics and its structural integrity. For someone like me who wants my pool to look good and function well, this is a big plus.

Buying Guide for Wall Foam for Inground Pools

Understanding Wall Foam and Its Purpose

When I first started looking into wall foam for my inground pool, I realized it’s primarily used as insulation and a protective layer. Wall foam helps to reduce heat loss, protect the pool walls from damage, and improve overall energy efficiency. Knowing this made me prioritize foam thickness and density to get the best results for my pool’s environment.

Types of Wall Foam Available

There are several types of foam commonly used for pool walls, including polystyrene (EPS and XPS) and polyurethane foam. I found that each type has different insulating properties and moisture resistance. Understanding these differences helped me decide which foam would withstand moisture and provide long-lasting insulation in my specific climate.

Thickness and Density Considerations

When I was selecting foam, thickness was crucial because it directly affects insulation performance. Typically, foam thickness ranges from 1 inch to several inches, and denser foam offers better protection and durability. I made sure to balance thickness with my budget and the structural requirements of my pool.

Moisture Resistance and Durability

Since inground pools are constantly exposed to moisture, I looked for foam that resists water absorption to prevent degradation over time. Closed-cell foam types tend to perform better in wet environments. This factor was essential to ensure my investment would last without needing frequent replacements.

Ease of Installation

I considered how easy the foam would be to install. Some foams come in panels or sheets that can be cut and fitted around the pool walls, while others require spraying or more specialized application. Choosing a product compatible with my installation skills or contractor’s methods saved time and reduced hassle.

Compatibility with Pool Wall Materials

My pool walls are made of concrete, so I made sure the foam I chose adhered well to this surface and wouldn’t cause any chemical reactions or damage. Checking compatibility with your pool’s wall material is important to avoid future problems.

Environmental and Safety Factors

I also looked into the environmental impact of the foam, including whether it contained any harmful chemicals or was recyclable. Safety during installation and use was a priority, so I chose foam that was non-toxic and met relevant safety standards.

Budget and Long-Term Value

While I wanted good quality foam, I balanced cost with performance. Sometimes paying a bit more upfront for higher-quality foam can save money in the long run by reducing energy bills and maintenance costs. I set a budget but stayed flexible for better value.

Final Tips from My Experience

• Always measure your pool walls accurately before purchasing foam.
• Consult with a pool professional if unsure about installation or compatibility.
• Factor in local climate conditions when choosing insulation thickness.
• Consider purchasing foam with warranties or guarantees for peace of mind.

By keeping these points in mind, I was able to select the right wall foam that enhanced my inground pool’s efficiency and longevity.
