How to choose the right 
projection screen
4
A choice may be made from the screen fabrics shown below. The selection
will be determined primarily by the light output of the projector, the ambient
light, the position of the projector (on the ceiling or placed at seat height)
and the layout of the presentation room.
Wide viewing angle 50° L/R
Matte White
Diffusion screen fabrics
Within the diffusion screen fabrics we offer the following variants: 
Matte White, fabric strengthen thermoplast, dataflex thermoplast and 
durbale thermoplast.
Suitable choice for applications which require a wide viewing angle 
(max. 50° L/R) or those in which a projector with a high light output 
is used. May also be used in situations in which the projector is placed 
at seat height as well as those in which the projector is mounted on 
the ceiling. 
All projector screen fabrics are tested for fire resistance and meet the 
norm B2.
Reflective screen fabrics
Screen fabric equipped with a special top layer for increased reflection. 
Particularly suitable for rooms with normal ambient light or a lower projector
output and a maximum viewing angle of 35° L/R.
All of the projection screen fabrics satisfy the requirements for fire resistance
of construction materials and components.
At the screen pages you can find the screenfabric per screen.
