Internal Cassette roller blinds ideally protect against the intrusive sunlight.  Aesthetic  rails prevent  sun light from coming through a window on both sides of the roller blind keeping the fabric in the same distance from the glass. The blind is made of monochromatic or patterned fabrics shading the room up to 70% or gummed ones shading in 100%. The cassette and rails are  made of aluminium, but the fabric is weighted by an aesthetic, steel, flat bar. The standard cassette roller blind is a non-invasive system glued to a window frame. It is found with a wide interest of the clients because of its universal mounting technique which allows fixing the blind on all kinds of windows. The cassette roller blinds are available in colours: white, brown, nut, golden oak.





Measurement of a cassette roller blind Premium is very easy. Following a manual will help you properly measure and mount the blind.

Making measurements provide only width and height of the glass with the glazing beads according to the instructional picture below.

In case of round glazing beads 2 cm extra are added to the provided width of the roller blind to fit the guide rails. To mount the guide rails properly at least 1 cm of flat surface is needed on each side of the window frame.

The entire width of the blind is approx. 3 cm larger than the width of the fabric (glass+glazing beads).



Mounting of a cassette roller blind is very easy because it is mounted to a window sash by strong foam tapes. Owing to such a solution the window keeps the warranty because we don’t use screws.


a. cassette

b. guide rail

c. end cap

d. pulley set

e. glazing bead

f.  window sash

step one - surface preparation

Window frame needs to be cleaned in places where a cassette and rails will be fixed

step two - guide rails mount

Remove a protection of an adhesive tape and glue two guide rails on both sides of  a window sash 1 centimetre from a glazing bead. Fixing rails should start from a handle side.

In case when  the distance from a handle to a glazing bead is shorter than 1 centimetre the guide rail should be fixed maximally close to the handle. Glue another rail proportionally far from a glazing bead as to place the roller blind in the central part of the window

step three - cassette mount

After having fixed guide rails remove protection of a cassette tape and glue it on the upper part of a window sash in such a way to put its edge in the same place as the rail’s edge. There should be a right angle between the rails and the cassette.

step four - setting the chain blockade

Next step is setting the brake in a roller blind. The fabric needs to be unrolled as to place the bottom bar evenly to rails edges. Additional blocker should be fixed near a cassette.

In the instructional video the guide rails are mounted on the glazing beads.

Such a solution is possible only with the flat glazing beads.

In case when the glazing beads are round the guide rails should be mounted next to them what, in effect, increases the entire width of the blind by at least 2 cm.

NOTE: Please measure according to the instructions in the "Measure" tab and not the following film. The film was included as an assembly instruction for blinds and not a measurement.


In order to dismount a cassette roller blind it is necessary to cut a tape along the cassette with a wallpaper knife until it is entirely cut off. Clean a blind and a window from tape wastes. A new tape needs to be used in case of another mounting.
