Léa's opinion on Luminis Films heat protection film
Impressive results after installation
Tired of baking under Velux windows in summer? So is our customer Léa! She tested the anti-heat film and gives us her opinion after installing it in her home.
The result: several degrees less and a real breath of fresh air in the house. Read about her experience!

Léa's problem
You may already know Léa as @decohomeby_l on social networks. A native of Tours, France, her passion for decoration and interior design has guided her towards a career as an interior designer and "Déco Coach".
Léa came to see us during the summer of 2023 because she was far too hot in her velux-equipped rooms: "It's a real furnace upstairs!" 🥵
So we helped him out by proposing Luminis Films heat-shielding films, cut to the size of his velux windows.
Equipped with a special window film installation kit, Léa managed to install her heat-shielding adhesive films herself. Every step of the installation was respected, and it shows: bubble-free installation, and a fully effective film, ready to face the summer heat! 🔥
Spoiler alter: she wasn't disappointed! 😉

The result after applying the heat-shielding film
Before, the inside temperature was almost identical to the outside temperature. After installing the heat-shielding film, Léa noticed a 6°C gain compared with before! ❄️
Conclusion: the outside temperature rises, and the room temperature falls much less.
Before applying the film, our customer installed a thermometer in her room. It showed 27°C outside, and 26°C inside her room. The inside temperature is almost identical to the outside temperature (1°C difference).
Once the film had been applied, Léa observed an outside temperature of 29°C, compared with 23°C inside. The difference is now 6°C! 😁
Second measurement: the thermometer indicates an outside temperature of almost 32°C, compared with 25°C inside! The meter climbs to 7°C difference! 🤩
And all without air conditioning. As well as getting more than satisfactory measurements, we met up with a delighted customer: "The heat doesn't just come in through the skylights, so we didn't magically gain 10°C, but those few degrees still make a big difference! 😀 ".
We contacted Léa again about 1 year later to get her feedback after several months' use, and she reiterated her satisfaction with the film'santi-heat effectiveness. Mission accomplished! 💪
Léa used this reference 👇

Focus on GLASS-200x heat protection film
For her double-glazed velux windows, Léa used the custom-cut GLASS-200X reference (exterior installation). This silver-metallized solar protection film offers excellent value for money!
✅ Excellent heat efficiency, rejecting up to 85% of solar energy
✅ It's lightly tinted but still lets in a lot of natural light
✅ You'll be protected from the heat without losing your view of the outdoors
✅ Excellent durability, up to 8 years
It's important to note that on velux windows, installation on the outside is strongly recommended to minimize the risk of thermal shock to the glazing.
It's your turn to lower the temperature in your home! Find out more about our products and order your Luminis Films heat-shielding films now for a cool summer. 💪❄️
