Solar window film, specifically the 2018 product line from Eastman Performance Films LLC (makers of LLumar, Vista, EnerLogic, and Hüper Optik), represents a specialized coating applied to glass surfaces to reduce solar heat gain, glare, and harmful UV radiation. This ultimately leads to improved energy efficiency, increased comfort, and protection of interiors.
Understanding Solar Window Film: The Essentials
Eastman Performance Films, a renowned leader in the window film industry, offered a robust selection of solar control window films in 2018. These films, including their well-known brands, are designed to address a range of needs, from enhancing energy efficiency in commercial buildings to protecting furniture from fading in residential homes. The “2018” designation refers to the specific formulations and technologies used in that year’s product releases, often incorporating advancements in materials science and application techniques.
The core function of these films revolves around manipulating the way solar energy interacts with glass. They achieve this through various mechanisms, including:
- Reflection: Reflecting a portion of incoming solar radiation back into the atmosphere.
- Absorption: Absorbing solar energy, preventing it from entering the interior. Absorbed heat is later dissipated outwards.
- Filtration: Selectively filtering out specific wavelengths of light, such as UV rays and infrared radiation, while allowing visible light to pass through.
The effectiveness of a particular solar window film is determined by its specific properties, measured by factors such as:
- Solar Heat Gain Coefficient (SHGC): A measure of how much solar heat passes through the window. Lower SHGC values indicate better performance.
- Visible Light Transmittance (VLT): The percentage of visible light that passes through the film. This impacts the brightness of the interior.
- UV Rejection: The percentage of harmful UV rays blocked by the film.
Benefits of Eastman Performance Films Solar Window Film
The benefits of using Eastman Performance Films’ solar window films in the 2018 lineup are multifaceted:
- Energy Savings: Reduced cooling costs due to decreased solar heat gain.
- Enhanced Comfort: A more comfortable indoor environment with less temperature fluctuation.
- UV Protection: Shielding interiors from harmful UV radiation, protecting furniture, fabrics, and artwork from fading.
- Glare Reduction: Reducing glare from sunlight, improving visibility and reducing eye strain.
- Improved Aesthetics: Some films can enhance the appearance of windows, adding a modern and stylish look.
- Security and Safety: Certain films can provide added security by making windows more resistant to shattering, potentially deterring break-ins. While not the primary purpose of solar film, some lines offer added protection.
FAQs: Delving Deeper into Solar Window Film
Here are some frequently asked questions regarding solar window film from Eastman Performance Films (specifically their 2018 offerings):
What are the different types of solar window film offered by Eastman Performance Films?
Eastman Performance Films offers a variety of solar window films under brand names like LLumar, Vista, EnerLogic, and Hüper Optik. These films vary in their composition (e.g., dyed, metallized, ceramic), thickness, color, and performance characteristics. Dyed films are typically the most economical, while metallized films offer superior heat rejection. Ceramic films are a premium option known for their excellent clarity and durability, avoiding metallic appearance. The EnerLogic line specifically focused on low-E technology adapted for retrofit application.
How do I choose the right solar window film for my needs?
Choosing the right film depends on your specific goals and requirements. Consider factors such as the amount of sunlight your windows receive, your desired level of heat rejection, your preferred visible light transmittance, and your budget. It’s crucial to consider the specific performance characteristics (SHGC, VLT, UV rejection) and compare different options. Consulting with an authorized Eastman Performance Films dealer is highly recommended.
What is the installation process for solar window film?
Professional installation is crucial for optimal performance and longevity. The process typically involves cleaning the window thoroughly, applying the film to the glass surface using a soapy water solution, and then squeegeeing out any excess water and air bubbles. Proper surface preparation is key to preventing adhesion issues.
How long does solar window film typically last?
The lifespan of solar window film depends on factors such as the quality of the film, the climate, and the installation quality. Eastman Performance Films typically offers warranties ranging from several years to a lifetime (for residential applications). Proper maintenance, such as gentle cleaning with a soft cloth and mild soap, can extend the film’s lifespan.
Does solar window film affect the visibility through the glass?
While all solar window films reduce visible light transmittance to some degree, many options are designed to minimize the impact on visibility. Clear films with high VLT values are available for those who want to maintain a bright interior. Darker films will significantly reduce glare and heat but will also dim the interior.
Can solar window film be applied to all types of glass?
Solar window film can be applied to most types of glass, but certain types, such as tempered glass, may require specific film types or installation techniques. It’s essential to check with an authorized dealer or installer to ensure compatibility and avoid potential problems like thermal stress cracking. Dual-pane or low-E windows require careful consideration.
How does solar window film help with energy efficiency?
Solar window film reduces energy consumption by decreasing the amount of solar heat that enters the building. This reduces the workload on air conditioning systems, leading to lower energy bills. The reduction in heat gain also allows for smaller, more efficient HVAC systems in new construction.
Will solar window film protect my furniture from fading?
Yes, solar window film significantly reduces the amount of harmful UV radiation that enters the building, protecting furniture, fabrics, and artwork from fading and discoloration. This is one of the primary benefits for residential applications and museums.
Is solar window film reflective?
Some solar window films are reflective, especially metallized films. The level of reflectivity varies depending on the specific film type. Low-reflective options, such as ceramic films, are available for those who prefer a more subtle appearance. Reflectivity is typically higher on the outside surface of the window.
What is the warranty on Eastman Performance Films solar window film?
Eastman Performance Films offers comprehensive warranties on their solar window films, covering defects in materials and workmanship. The length of the warranty varies depending on the film type and the application (residential vs. commercial). Always check the warranty details before purchasing and ensure the installer is an authorized dealer.
How much does solar window film cost?
The cost of solar window film varies depending on the film type, the size of the windows, and the complexity of the installation. Obtain quotes from multiple authorized dealers to compare prices and ensure you are getting a fair deal. Remember to factor in the long-term energy savings and other benefits when evaluating the cost.
How do I find an authorized Eastman Performance Films dealer?
You can find an authorized Eastman Performance Films dealer by visiting their official website and using the dealer locator tool. Authorized dealers have the training and expertise to properly install the film and provide warranty service. They can also help you choose the right film for your specific needs.
