When should I apply a building film on the interior and when on the exterior?

The decision to apply a building film on the interior or exterior depends on various factors, including the desired function, weather resistance, and the specific conditions of your building.

1. Interior Application:

   • Sun Protection: Interior films are ideal for protecting indoor spaces from excessive sunlight. They reduce heat and block UV rays, keeping the indoor climate cool and protecting furniture from fading.
   • Ease of Installation and Maintenance: Interior films are more accessible, making them easier to install and maintain.
   • Longer Lifespan: Since they are not exposed to weather conditions, they typically last longer.

2. Exterior Application:

   • Maximum Heat Reduction: Exterior films block sunlight before it reaches the glass, making them the most effective option for reducing heat. They are particularly suitable for buildings with large glass surfaces exposed to intense sunlight.
   • Weather Resistance: Exterior films are designed to withstand elements such as rain, wind, and temperature fluctuations. They are durable but require professional installation to ensure optimal performance.

Summary:
When choosing between interior and exterior applications, consider the structural conditions of your building and your specific needs. Interior films are ideal for durability and ease of maintenance, while exterior films provide superior heat reduction for sun-exposed glass surfaces. Consult a professional to find the best solution for your requirements and enhance both comfort and energy efficiency.
