Seasonal anti-heat solution: scratch film or electrostatic film?

Anti-heat scratch film: 

Ideal for skylights or verandas, the scratch anti-warmth film is applied directly to the frame of your windows using scratch pads. You just have to install the scratch strips on the frame of the glass to be fitted, then apply the second scratch strips directly to your film to finish fitting your seasonal heat protection film with ease!
You can remove and reapply the repositionable heat protection film as often as you like! As with static heat protection film, we recommend that you store the film in a clean, dry place so that it does not become damaged from year to year.
This type of film will give a subdued light to your interior because it is ultra efficient against heat. In fact, its composition allows it to reject up to 92% of the sun's energy!
 

The electrostatic heat protection film :

Easy to install, infinitely removable, durable and reusable... there are many benefits to choosing a electrostatic heat protection film ! 
This type of film is as easy to apply as it is to remove and can therefore only be used in summer. You can choose from the most efficient films which, thanks to their special composition, can absorb up to 87% of the solar energy. Suitable for indoor and outdoor use, the film electrostatic heat shield is slightly less clear than an adhesive, but will still allow you to maintain visibility to the outside. With their anti-uv and anti-glare filter, these heat protection films will quickly become your summer ally! 
To reuse it from one year to the next, make sure you clean your film when you remove it and store it in a clean, dry place until the following year.
