The use of glass in the construction sector has grown rapidly: new buildings are often designed with glass facades or large windows that give an immediate sense of modernity.

The risk, however, is that there will be problems in terms of living comfort, because it is possible that the interiors, with greater exposure to the sun, might overheat, especially during the summer season.

Solar control is therefore essential to ensure a comfortable indoor temperature and is also important for energy saving.

It is for this reason that Satinal has developed ³§°Õ¸é´¡°Õ°¿Â®&²Ô²ú²õ±è;¹ó¸é·¡³§°ä°¿, a new generation of high performance EVA film using nanoparticle technology.

FRESCO is designed to give laminated glass more efficient solar heat control properties than monolithic transparent glass and laminates with traditional transparent EVA film: the film absorbs UV rays and infrared energy (NIR), allowing maximum visible light transmission.

The graphic clearly shows this concept: a laminated glass with EVA film without protection

UV-IR (yellow line), has a high transmission of visible light but allows to pass both UV rays, very harmful to people and objects, and Infrared rays.

However, if we analyse the behaviour of a laminated glass with one (blue line), two (line orange), or three films (grey line) of ³§°Õ¸é´¡°Õ°¿Â®&²Ô²ú²õ±è;¹ó¸é·¡³§°ä°¿, you will notice that the value of the transmission of the visible light (max 80%), is opposite to that of the infrared rays (min. 5%).

These characteristics are very important because they let you recreate in buildings, houses and apartments, a comfortable indoor environment, especially during the summer season.

By reducing the use of air conditioning, you will get economic benefits – reduction of electricity costs – and also environmental – reduction of greenhouse gas emissions-.
