Which Film for Windows?

Which film is suitable for windows?

The choice of window film depends on the purpose you want it to serve. Below is an overview of the most common types of window films:
Decorative and frosted films for privacy on windows
To stop prying eyes, decorative glass film or frosted film is applied to windows. Both films allow light to pass through while blocking clear visibility. Typical uses include privacy protection in public spaces such as hospitals, offices, or administrative buildings. These films serve both as decorative privacy screens and visual markers on glass doors in public areas.
Films for window lettering
For window lettering, a matte film such as the SUPERIOR 4100 Matt is usually preferred because glossy films can reflect light, which may reduce the readability of the message. It is advantageous if the matte film uses a semi-permanent adhesive, making it easier to remove later without leaving residue.
Sun protection films for windows
The Nexfil HP Silver 20 EXT is a high-quality, self-adhesive sun protection film designed for exterior application. It provides reliable protection against heat, UV radiation, and glare. Its silver mirror finish not only gives a modern look but also reduces indoor heat build-up – ideal for windows in office buildings, industrial buildings, or private homes.
Important: Installation must be on the outside of the window. Applying sun protection film to the inside of double- or triple-glazed windows can cause the space between the panes to overheat, which in the worst case may lead to glass cracking.
