How long is the average lifespan of foils sold by comfort-films?
These kind of foils belong to our Premium Films and can be divided into two sections with different lifespans:
Indoor foils: 10 - 15 years
Outdoor foils: 5 - 7 years, due to weather and downtilt (e.g. skylights).

We guarantee:
Indoor foils: 10 years
Outdoor foils: 4 - 5 years
Can the foils be removed free of residues?
All of our films are coated with the so-called HIGH-PEEL-glue, meaning that they can be removed virtually free of residues.
Do reflective films really help conceal the indoors from outside viewers?
Depending on the mirror-effect density our e.g. Spyfilm Silver 15 will completely shield your privacy from outside gazes.
Please note: To achieve this affect it has to be lighter outdoors than indoors!
How should I clean the glass before fitting the foil?
Details on how to prepare the glass you may find in our rubic ·Assembling·.
What is infra-red radiation?
Infrared radiation is electromagnetic radiation with a longer wavelength than visible light (400-700 nm), but shorter than the terahertz radiation and microwaves (~30,000 µm). Infrared radiation spans roughly between 780 nm and 1400 nm. Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared (47% share of the spectrum), visible (46%), and ultra-violet (only 6%) light. Material exposed to infra-red rays partially absorb this radiation and transform it into heat.
