Inspiration

VION window films are renowned for their exceptional performance and innovative features. But have you ever wondered about the science behind these remarkable films? Today, we’ll explore the technology and mechanisms that make VION window films so effective. Understanding the science behind VION window films will help you appreciate their capabilities and make an informed decision when choosing the right window film for your needs.

Multiple Layers of Performance

VION window films are engineered with multiple layers, each serving a specific purpose. Let’s take a closer look at these layers and their functions.

• Hard Scratch Resistant Layer: The hard scratch-resistant layer in VION window film is a durable coating applied to the film’s surface to enhance its resistance against scratches and abrasions. This layer helps protect the film from everyday wear and tear, ensuring a long-lasting and visually appealing appearance.
• High Optical Quality Polyester: The high-quality polyester layer is a central component of VION window film. Made from high-grade polyester material, this layer provides excellent clarity and transparency, allowing for unobstructed views through the window while still providing effective heat and UV protection.
• Bonding Adhesive: The bonding adhesive layer serves as the glue that attaches the window film to the glass surface. It is designed to create a strong and secure bond between the film and the window, ensuring long-term adhesion and minimising the risk of peeling or bubbling.
• High Optical Quality Polyester: Another layer of high optical quality polyester is included in the construction of VION window film. This additional layer further enhances the film’s optical properties, maximising its ability to transmit natural light and maintain clarity without compromising its performance.
• PS Adhesive: The PS adhesive layer, also known as pressure-sensitive adhesive, is responsible for the ease of installation of VION window film. This adhesive allows for a straightforward application process by sticking to the glass upon contact and can be repositioned if necessary during installation. It provides a strong bond while avoiding the need for additional activation methods such as heat or moisture.
• Protection Release Liner: The protection release liner is a thin protective sheet that covers the PS adhesive layer before installation. It is removed during the application process, exposing the adhesive for attachment to the glass. The release liner serves as a barrier to prevent the adhesive from prematurely sticking to surfaces or collecting dust or debris before the film is installed, ensuring a clean and professional application.

Heat Rejection and Energy Efficiency

VION window films are designed to reduce heat transmission through windows. This is achieved through two fundamental mechanisms.

• Reflective Technology: Some VION window films incorporate reflective technology, using microscopic metallic particles within the film. These particles reflect a portion of the sun’s heat, preventing it from entering the interior space and reducing the reliance on air conditioning. The degree of reflectivity can be customised based on the film’s specifications and intended application.
• Absorption and Dissipation: Other VION films utilise absorption and dissipation properties to reduce heat transfer. These films contain materials that absorb solar energy, converting it into negligible amounts of heat that are then dissipated through the glass. This mechanism helps maintain a more consistent and comfortable temperature indoors, reducing the strain on cooling systems and enhancing energy efficiency.

UV Protection

VION window films offer excellent protection against harmful ultraviolet (UV) rays. These films incorporate UV-blocking additives and coatings that act as a shield, preventing up to 99% of UV radiation from passing through the windows. This protection helps safeguard your skin from UV-related health risks and minimises fading and damage to interior furnishings, such as carpets, furniture, and artwork.

Glare Reduction

Glare can be a major source of discomfort and distraction. In fact, it's such a problem that we have an entire post dedicated to it! VION window films are engineered to minimise glare by utilising advanced light-diffusion technology. These films scatter and diffuse incoming light, reducing its intensity and creating a more balanced and visually comfortable environment. By reducing glare, VION films improve visibility and allow for increased productivity and enjoyment in various settings.

VION window films are the result of cutting-edge technology and scientific innovation. The multiple layers, including the adhesive, polyester, metal or ceramic coating, and protective top coat, work together to provide exceptional performance. Through their heat rejection, UV protection, and glare reduction capabilities, VION films contribute to energy efficiency, occupant comfort, and the preservation of interior spaces.

Understanding the science behind VION window films empowers you to make an informed decision when selecting the right film for your specific requirements.
