How do I reduce energy consumption using adhesive films for windows?

Reflectiv created an adhesive film for windows that provides summer and winter comfort, enabling energy consumption to be reduced both in summer and winter. This film, which features small reflective aluminium dots, enables up to 48% of the heat in summer to be reflected, thereby enabling the use of air conditioning to be reduced, while in winter on the other hand, due to the height of the sun (which is lower in winter), it allows rays to enter so that the room can be heated naturally.
