Velux roof film Comfort and coolness under your roof windows
The Captain Film roof window film is the ideal solution to improve the comfort of your attic rooms on a daily basis. Designed to perfectly fit roof windows, it effectively reduces glare and heat while still allowing natural light to enter. It helps limit overheating in summer and protects against UV rays. Discreet and efficient, it allows you to fully enjoy your attic spaces in every season.
A Velux without protection can raise the temperature of a room by 8 to 12°C in summer. Blackout blinds cut the light. Replacing the glazing costs a fortune. There is a better way.
Unbearable heat
Bedroom or office under the roof: impossible to sleep or work from May onwards.
Blinding light
Direct sun through the roof window makes screens unreadable and wakes you at dawn.
Expensive solutions
Original Velux blinds cost up to €400 per window, installed by a professional.
No UV protection
Standard Velux glazing lets through nearly all UV rays, fading everything below.
Why choose film for your Velux?
Our film vs the two most common roof window solutions. The choice is obvious.

Effective but allow time to install properly
“The film really works; I noticed a clear temperature difference this summer. On a large bay (2.5 m), you really need two people to avoid creases.”

“I made a measurement mistake; support sent a free recut within 48h. Installed on 4 windows in June — I finally sleep at night again. The bedroom cools down quickly.”
Visible Light Transmission iVLT (Visible Light Transmittance): The VLT (visible light transmittance) refers to the percentage of visible light that passes through the film. A high VLT allows more natural light to pass through, while a low VLT reduces glare and preserves privacy. For example, a VLT of 50% means that half of the visible light passes through the film.-
VLR iVLR (Visible Light Reflection): VLR indicates the percentage of visible light reflected by the window film. A high VLR means the film reflects more light, which can enhance the building’s exterior appearance and reduce glare. However, excessive reflection may be undesirable in certain contexts.-
UV Rejection -
TSER iTSER (Total Solar Energy Rejected): TSER represents the total percentage of solar energy (including heat, ultraviolet, and infrared radiation) rejected by the solar control film. A high TSER means better heat protection, helping to keep indoor spaces cooler and improving energy efficiency by reducing the load on air conditioning systems.-
