(Specifier Note: The purpose of this guide specification is to assist the Specifier in correctly specifying
Cinescreen rear projection screens and their installation. The Specifier needs to edit these guide
specifications to fit the needs of each specific project. References have been made within the text of the
specification to MasterFormat section numbers and titles. The Specifier needs to coordinate these
numbers and titles with sections included for the specific project.
Throughout the guide specification, there are Specifier Notes to assist in the editing of the file. Desired
options for substrate material, formulation of optical coating, tint of optical coating, surface treatments,
sizes, method of installation, frame type and finish need to be noted. Brackets have been used to indicate
when a selection is required. Unless noted otherwise, the first option is the standard feature. Contact a
Draper, Inc. representative for further assistance with appropriate product selections.
Rear projection screen systems must be properly designed and constructed in accordance with
guidelines provided in Draper product literature. An AV consultant or expert should be involved whenever
possible. Coordinate protection against light spills with flat black paint, doors with room-in-use warning
lights, and windows sealed with lightproof shades specified in other sections.)

REAR PROJECTION SCREENS
A.
Diffusion Type Rear Projection Screen: Rigid transparent substrate with permanently bonded
optical coating which diffuses and distributes projected light. Assembly to include all
gaskets, setting blocks, fasteners, and other components necessary for complete installation
1.
Basis-of-Design: Cinescreen Rear Projection Screen.
(Specifier Note: SELECT one of two substrates paragraphs and basis-of-design sub-paragraphs below.
Cineglass is recommended for maximum sound isolation, scratch resistance and service life. It is flatter
than acrylic in large sizes, providing better image resolution but weighs approximately twice as much as
acrylic, breaks more easily and should be installed by a glazier. Maximum screen size is 72 by 150 inches
(1829 by 3810 mm) for 1/4 inch (6 mm) thickness, 126 by 204 inches (3200 by 5182 mm) for 3/8 inch (10
mm) thickness, and 126 by 289 inches (3200 mm by 7341 mm) for ½ inch (13 mm) thickness.
Cineplex is lightweight, durable and break resistant. It is easier to install than Cineglass but requires more
care in cleaning since it will scratch more easily. It is less soundproof than glass and not recommended
for multiple projector installations. Maximum screen size is 90 by 160 inches (2286 by 4064 mm) for 1/4
inch (6 mm) thickness, and 104 by 192 inches (2642 by 4877 mm) for 3/8 inch (10 mm) and ½ inch (13
mm) thickness.

Substrate: Clear, select quality plate or float glass.

REAR PROJECTION SCREENS
Draper, Inc. Cinescreen Rear Projection Screens
1.
Basis-of-Design: Cineplex, as manufactured by Draper, Inc.
(Specifier Note: The thicker a substrate is, the more rigidity it has. Since maximum screen size is limited
by the thickness of a substrate, an AV consultant should determine initial substrate thickness
requirements. The mechanical engineer and architect should then determine if environmental
considerations, such as air pressure from HVAC systems, or program use, such as detention facilities,
require a thicker substrate. The optical quality is not affected.)
2.
Thickness: [1/4 inch (6 mm)] [3/8 inch (10 mm)] [1/2 inch (13 mm)]
(Specifier Note: Coatings are formulated to provide varying levels of brightness over different viewing
angles. Screen surfaces are rated according to gain which is a measure of brightness relative to a block
of magnesium carbonate which serves as the standard for 1.0 gain. A higher gain indicates an increase
in brightness. Peak gain is measured directly in front of the screen at 0 degrees viewing angle. Gain will
decrease with an increase in viewing angle.
Selection of optical coating is influenced by projector light output, audience pattern, screen aspect ratio,
and ambient light level in audience area.
Refer to Draper product literature at
http://www.draperinc.com/ProjectionScreens/rearCinescreenOpticalCoating.asp for further assistance in
selection of appropriate optical coating.
SELECT one of three optical coatings listed below:
Cine 10;
Cine 13;
Cine 15;
C.
1.0 peak gain and half-gain at 50 degrees.
1.3 peak gain and half-gain at 33 degrees.
1.5 peak gain and half-gain at 31 degrees.
Optical Coating: Emulsion of microscopic particles each functioning as a refractive lens with
peak gain at 0 degree viewing angle of [Insert peak gain] and half-gain at [Insert degree]
degrees.
1.
Basis-of-Design: [Cine 10] [Cine 13] [Cine 15] as manufactured by Draper, Inc.
(Specifier Note: Selection of optical tint is influenced by type of projector, contrast and legibility of
projected image, ambient light level in audience area, acceptable color when screen is not in use, and
use of laser pointers. For assistance in selection of appropriate optical tint, refer to Draper product
literature at http://www.draperinc.com/ProjectionScreens/rearCinescreenOpticalTints.asp.
SELECT one of three optical tints listed below:
Cine HC - High contrast dark grey tint.
Cine NG - Medium grey tint normal contrast tint.
Cine W - Neutral white tint.)
D.
Optical Tint: Provide [Insert tint color] modifier for optical coating to enhance image
contrast and color value.
1.
Basis-of-Design: [Cine HC] [Cine NG] [Cine W] as manufactured by Draper, Inc.
(Specifier Note: Screen size is determined by dimensions of audience area, ceiling height, and use.
Draper provides both standard and custom sizes for rear projection screens. Maximum sizes are limited
by thickness of screen substrate as indicated in thickness Specifier Note above. COORDINATE maximum
screen sizes with frame type or video wall framing system when specified below.)
