Flexible privacy protection with switchable films for glass

Privacy at the touch of a button! Your glass becomes intelligent - turn your glass into smart glass!

With the switchable films in the ClickFilm® range, HAVERKAMP has developed products that turn transparent glass surfaces into frosted privacy protection at the touch of a button. Welcome to the future of glass utilisation: the milky and transparent switchable ClickFilm® films work with a polymer-dispersed liquid crystal interlayer (PDLC). When frosted, the electrically switchable films offer privacy and can also be used as a projection or advertising surface. Spaces can thus be used for a wide variety of purposes: flexible, versatile and spontaneous!

The switchable films from HAVERKAMP are ideal for retrofitting glass, which saves considerable costs. They are also available as interlayer films for use in glass production.

Using HAVERKAMP ClickFilm® as a projection surface

The switchable film turns a glass partition into a projection surface with an optimal sharp image. Due to the white color variant, the film can be ideally used as a projection surface for photos or beamer projections in meeting and presentation rooms.

The technology of electric privacy glass film

Over 2 million switching operations possible

The effect of the switchable privacy screen HAVERKAMP ClickFilm® is created with electricity. As soon as the power voltage (60-65V AC) is switched on via remote control or app, the film is transparent. A transformer drives the liquid crystal polymers in the middle layer of the film. The power supply causes the crystals to stand up straight. This is how the transparency of the smart windows film ClickFilm® is created. If the control or power supply is missing, the polymers are not aligned and a visual barrier is created..

HAVERKAMP ClickFilm® switchable films require sophisticated control technology in order to achieve their best technical values and to be able to achieve their full performance. Here too, HAVERKAMP has brought its own developments to the fore. In addition to the connections, the busbar and the cabling, our own transformer development contributes to the complete HAVERKAMP ClickFilm® solution. The transformer allows the films to be individually switched, dimmed or partially controlled.

HAVERKAMP ClickFilm® convinces with the best optical transparency available on the market.
The light transmission of the white PDLC film is over fantastic 82%. The switching time achieves best values of 150ms from off to on and 210ms from on to off. The optional dimmable film can be switched by remote control or via app. Thus, the intelligent film can be controlled even from a distance. In addition, switching in segments is possible. The glass becomes a tangible surface. The transformer developed by HAVERKAMP is precisely matched to ClickFilm® and ensures low power consumption. ClickFilm® operates faultlessly and is maintenance-free as well as removable without leaving any residue if required. The HAVERKAMP smart film is also easy to clean with conventional cleaning agents.

With a switchable film, it is possible to change from opaque to clear and vice versa at the touch of a button. It is suitable for retrofitting on all flat glass surfaces  it´s many times more cost-effective than a complete glass replacement. In addition, the product can be used as a projection surface. HAVERKAMP's smart  film ClickFilm® is also available for vehicle windows.

HAVERKAMP ClickFilm® for automotive

The matting (= visual protection) is available in the color variant white and gray. The white PDLC film is ideally suited for rear projection via beamer. Also available in dark gray for vehicle windows.

The areas of application are unlimited, as it can be retrofitted as a flat glass film on almost all flat glass surfaces. Thus, a PDLC film can be used as a classic privacy screen and also as a projection screen with a beamer. Classic areas of use are meeting rooms, work areas, retail, in the use of equipment doors such as refrigerators, vehicle windows, business lounges but also private areas such as bedrooms or living rooms.

All HAVERKAMP smart films are prefabricated to size before the product is installed. The installation of the smart film should be done by trained professional installers, and the power connection should be done by an electrician. You will receive an installation video for this purpose. Alternatively, you can contact a HAVERKAMP partner and purchase the product. To present the film to your customers up close, you can purchase a sample box from us.

Cleaning the smart film ClickFilm® is easy, but should only be done with cleaning agents recommended by HAVERKAMP.

Yes, the product provides UV protection of 99% of incoming UV-A and UV-B rays. The UV transmission of our smart films is thus < 1 % (300 - 380 nm).

Since each film is made to measure, our customers can choose the side of the cable connection. We always recommend the connection on a long edge. We will be happy to advise you on this!

Yes, this is possible. The smart films are mounted at a distance of less than 1 mm. The so-called butt edge must then be sealed, but this is visually very inconspicuous.

The Power Transformers developed by HAVERKAMP are available in different versions depending on the requirements of the glass surface to be switched. Up to 45 m2 of glass surfaces coated with ClickFilm® can be controlled with one Power Transformer from HAVERKAMP.
You can connect several films to one transformer.

Yes, due to a specially developed transformer, a switchable film is also optionally dimmable. Did you know that several switching functions are possible with only one transformer?

No, in order not to restrict the visual appearance, the cables are always covered by a strip.

Since weather conditions can affect the effectiveness of the film, a switchable film must always be installed from the inside. The edge of a film can draw moisture, so unsightly stains can appear.

Due to a special adhesive, all HAVERKAMP films can be dismantled without leaving any residue. You can simply pull the smart film off the glass. If adhesive residues should remain on the pane, they can be removed with glass cleaner and a glass scraper. Please note that you cannot use the smart film again afterwards.
