How does anti-heat film improve thermal comfort in your home?
Anti-heat window film: improve your comfort
In summer, heat can quickly turn your home into an oven. This rise in temperature is detrimental to occupant comfort, especially in rooms with a lot of glass. Fortunately, there's a simple, effective and long-lasting solution: Luminis Films anti-heat window film!
But how does it work in practice? And what benefits does it bring to everyday life? We explain everything you need to know to enjoy a cool, pleasant home without the need for full air conditioning.

Why does heat enter through windows?
There are two reasons why heat enters through your windows.
The greenhouse effect through glazing
When a ray of sunlight strikes a pane of glass, some of the heat is absorbed by the glass surface, but much of it penetrates into the room. This creates a greenhouse effect: heat accumulates and remains trapped inside. The result? A sensation of stifling heat, even when the outside begins to cool.
Areas most affected
Some parts of your home are more vulnerable than others:
- South-facing bay windows;
- Verandas, real solar collectors in summer;
- Windows without shutters or with little protection.
These areas can raise indoor temperatures by several degrees if not effectively protected.
Anti-heat film: how does it work?
Infrared ray reflection
Solar window film acts as an invisible shield. It is designed to reflect infrared rays, which are the main source of heat. By filtering these rays even before they pass through the glazing, the film significantly reduces interior temperatures.
