What's the Melting Point of Siding, and Why is your siding melting?

Your New Siding is Melting, Why?

In this article, we dive into the issue of siding melting and warping, a common problem faced by many homeowners. We will discuss why this happens, what what you can do to protect your siding, what to lookout for when choosing to upgrade your siding and what your can do to make sure it doesnt cost you thousands of dollars in damage.  

The Science Behind Siding Melting

Siding materials, particularly vinyl, are susceptible to warping at high temperatures. The concentrated sunlight reflecting off windows can elevate temperatures, causing the siding to reach its melting point, which varies across materials.

As a window film expert, it's crucial to understand how different siding materials react to heat, particularly when it comes to low-E window reflections. Here's a brief overview:

• Vinyl: It's popular due to its low maintenance and cost-effectiveness, but it's vulnerable to warping or melting from intense reflected heat. Its melting point is around 165°F (74°C).

• Wood: Offers a beautiful, natural look and is energy-efficient, but can warp or dry out when exposed to high heat.

• Fiber Cement: This material is highly resistant to heat, pests, and moisture, making it a good choice against window reflections.

• Metal Siding (Aluminum, Steel): Metal sidings, particularly aluminum, are resistant to warping and handle temperature fluctuations well.

• Stucco: Made with cement, it's generally durable but can develop cracks under extreme heat fluctuations.

• Brick: Extremely durable and weather-resistant, but uneven heating can lead to moisture issues due to its porosity.

• Fiberglass: Known for its strength and light weight, fiberglass siding holds up well against heat.

• Engineered Wood: A stronger and more heat-resistant alternative to natural wood, though still susceptible to high temperatures.

• Composite Siding: Its heat resistance varies based on composition but generally performs better than traditional wood.

• Stone: Excellent in resisting heat, making it less prone to damage from low-E window reflections.

Understanding these characteristics helps in recommending the right window film products to protect various types of siding from potential heat damage caused by low-E windows.

Understanding Glass and what causes it to Melt Siding

Various types of glass can cause reflections intense enough to melt siding or warp it, with low-E (low emissivity) glass being a significant contributor. Here's a detailed overview:

• Regular Glass: Traditional glass can reflect sunlight, but typically not with the intensity to cause damage to siding.

• Low-E Glass: Low-E glass is designed to improve energy efficiency by reflecting infrared and UV light, reducing heat transfer. However, this reflective quality can inadvertently direct concentrated sunlight onto nearby surfaces, raising their temperature significantly. The intensity of the reflection depends on the coating's thickness and the angle of the sun.

• Tinted Glass: While tinted glass absorbs and re-radiates solar energy, it can also cause reflections, though generally less intense than low-E glass.

• Tempered Glass: Often used for safety, tempered glass can sometimes create more focused reflections due to the stress patterns within it.

Low-E glass is particularly notable for its potential to cause siding damage. Its metallic oxide coating, though thin, is highly effective at reflecting heat. This reflected heat can be much more intense than from regular glass, enough to melt vinyl siding or warp other materials. The risk is highest when the sun is at a low angle, as the reflected rays are more direct. Understanding these properties is crucial for selecting window films that mitigate these reflections without compromising the energy efficiency benefits of low-E glass.

Real-Life Siding Melting Scenarios

Reflective damage from windows, particularly those with low-E (low emissivity) coatings, has become a notable issue in recent years. These windows, designed for energy efficiency, can unintentionally cause significant damage to nearby properties.

Vinyl siding is particularly susceptible to this phenomenon. It typically starts to distort or melt at temperatures around 165-170 degrees Fahrenheit. The concentrated beams of light from low-E windows can easily exceed these temperatures, leading to melting and warping of the siding. This problem is not limited to vinyl; other materials like wood, composite decking, and even car parts can be affected under the right conditions, such as clear, sunny days and specific angles of sunlight reflection.

Homeowners have reported various instances of damage caused by window reflections. Issues range from melted siding and warped composite decking to burned patio cushions and even incidents of fires. In some cases, the intense reflection from a neighbor's low-E windows started the fires, demonstrating the potential severity of this issue.

For more detailed information and to read about specific instances of this problem, you can explore the sources from GreenBuildingAdvisor, Vinyl Siding Institute, Premium Siding Supply, and USGlass Magazine. These resources provide a comprehensive view of the challenges posed by window reflections and practical solutions to mitigate these risks.

Reflect Defense Window Film and How it Protects Siding from Melting

Reflect Defense Window Film is a specialized product designed to tackle the issue of siding melting due to intense window reflections, particularly from low-E glass windows. Its effectiveness is rooted in several key features:

1. Exterior Application: This film is applied to the outside surface of windows. This strategic placement allows it to interact directly with incoming sunlight, effectively diffusing and redirecting harmful reflections away from nearby surfaces, including siding.

2. Thermal Expansion Compatibility: The film is constructed to expand and contract in tandem with the glass. This feature minimizes the risk of thermal fractures, a common issue with some window films, especially when there's a significant temperature difference across a glass pane. It is suitable for various glass types and coatings, providing versatility for modern buildings that use different glass types for energy efficiency and aesthetics.

3. Prevention of Reflective Heat Damage: Reflect Defense Window Film significantly reduces the intensity of heat reflected by windows. This is particularly important for low-E windows, which, while energy-efficient, can inadvertently reflect and focus sunlight onto adjacent surfaces, causing them to overheat and potentially melt or warp.

4. UV Protection: The film blocks a substantial portion of harmful UV rays, which not only helps protect the siding but also reduces fading and degradation of various materials both outside and inside the home.

5. Energy Efficiency and Aesthetic Preservation: Despite its protective features, the film maintains the energy-efficient benefits of the windows and does not significantly alter their appearance, preserving the aesthetic appeal of the home.

6. Safety Concerns Addressed: The film is designed considering the potential for pre-existing damage to the glass. Therefore, it is recommended to inspect the glass for any damage before applying the film to ensure its integrity.

In essence, Reflect Defense Window Film offers a multifaceted solution that not only protects siding from melting but also enhances the overall functionality of windows. Its unique construction and application method make it a reliable choice for safeguarding your home against the unintended consequences of reflective window damage.
