BERGAFLEX sunscreen with  steel wire designed to guide the film sideways and to maintain the distance to the window.


Produced in cassette 027/S as a cord reel type, in cassette 058/S and 069/S as a cord reel or band reel version, or motorised with a 220V/1 phase 50–60 Hz tube motor.

Metallised Films

Ordinary water boils at 100°C at sea-level. At the top of Mount Everest where the air pressure is lower, however, water boils much quicker. In a vacuum (1/100,000 air pressure) aluminium, copper, titanium and stainless steel will all boil when heated. The steam from the melting metal condenses onto a plastic film where it is steered and controlled in order to achieve:


• increased light transmission/light reflection

• the required level of heat resolution

• the required electrical conductivity.


Pigmented Films

Colour pigments, metal pigments and other microscopic particles float in a high-pressure bath and are pressed into the film from both sides. The longer the film is left in the bath, the more pigment it absorbs. Once encapsulated within the film, the pigments are protected against UV-rays.


The choice of pigments determines the levels of light and heat absorption, as well as the colour of the light that penetrates the film.


Combination Films

As the name implies, combination films are a combination of a metallised film with either one or two different dyed films, or a combination of two dyed films.

Films can be used in BERGAFLEX shades, or permanently laminated to a window with the addition of another layer of glue.


Why Metallised?

Metallised films act as mirrors – they have a unique ability to reflect high-intensity rays from the sun. This indoor solar protection is relatively cheap to buy and maintain. It also has an unsurpassable service life and is not affected by weather, corrosion or pollution.



Our shades work in combination with metallised films and blackout materials. They are made with protective and functional aluminium casings. We measure up and produce the shades to integrate fully with all types of windows.


Our side rails are adequately proportioned, and may be directed and combined with our aluminium casings. For operating purposes, we can offer a cord reel or roller spring unit for casing 027, a cord reel, a tape reel shades spring unit or an electric motor for casing 069.


When choosing metallised films, you should consider three factors:

1. Light transmission

2. Shading coefficient

3. Light colour


For blackout shades, fabrics are available in different colours and with different properties (fire proof, etc.). We can, however, also use a fabric of the customer’s own choice. We measure up, make and fit the shades ourselves or via our authorised retailers.

Laminated Films

These change and add value to standard window glass. Depending on the individual film, the following effect may be achieved:


• reflective glass

• light- and heat-absorbent glass

• sanitary glass

• protective glass


Most films are laminated on the inside of the glass, but some films are tested and approved for use on the outside. These are suitable for the lamination of insulated glass for which any still-valid insurance warranty against glass breakage may expire if laminated on the inside.


Please contact us for advice on the treatment of insulated glass.


Reflective Glass

Different degrees of light transmission and shading can be achieved depending on the degree of metallisation.


Absorbing Films

Different degrees of light transmission and heat absorption can be achieved depending on the degree of pigmentation.


Combination Films

These are a combination of reflecting and absorbing films. Most films fall into this category.


Dispersing Films

Depending on the treatment and structure of the film, light dispersion will be achieved. The addition of pigment results in coloured light.


This film is suitable for use in dressing rooms and sanitary establishments, where a good light supply is required during the day but privacy is desirable at night.


Safety Films

Different thickness levels exist for different safety requirements. Some are available with a metallised treatment (see separate product sheet).
