Solar Window Panels

  • That depends on the film you choose. Many modern films are designed to reduce heat and glare while maintaining high levels of natural daylight. The number to look for is the VLT%. You can see an approximation of the effect of different VLT percentages below.

  • Yes. It is installed directly onto existing glazing, making it a cost-effective alternative to replacing windows.
  • Yes. Solar control films are particularly effective in offices, classrooms, reception areas and other environments where screen visibility is important.

  • Some reflective options can improve daytime privacy while still allowing occupants to see out.
  • Installation times vary depending on the size and complexity of the project, but most installations can be completed with minimal disruption to day-to-day operations.
  • Every glazing system and building environment is different. We can provide samples, explain the performance differences between films, and recommend the most suitable solution based on your glazing, building orientation, and objectives.

    Whether your priority is reducing heat, controlling glare, improving privacy, or maintaining the appearance of your windows, we'll help you make an informed decision. The table helps you compare various options.

    TSER - TOTAL SOLAR ENERGY REJECTION

    The percentage of total solar energy (including UV) that is rejected by the film. Higher is better as long as the VLT is not too low.

    VLT - VISIBLE LIGHT TRANSMISSION

    The amount of visible light that passes through the film. Higher percentages allow more natural light into the room.

    LES RATIO - LIGHT TO ENERGY SOLAR RATIO

    The ratio of visible light to solar energy that gets through. Higher is better because you get more visible light for each unit of heat.

    Solar protective films specially developed for building windows are composed of rigid polyester, thus offering easy indoor and outdoor application.

    These films boast remarkable durability to up to 10 years and high technicality, blocking UV rays up to 99%. This special range offers numerous benefits: UV protection, temperature control, privacy, brightness, decoration, safety (against glass breakage, thermal shocks, intrusion, scratches).

    Ultra-transparent film, tinted mirror or one-way mirror appearance, dichroic effect... depending on your need Fastsigns Portsmouth offer a high-quality solution for any type of glazing.
