INTERIOR
SUN CONTROL LOUVER SYSTEM
*****
Skyshield International, Inc. manufacturers several types of
aluminum skylight blinds and sun control shades. These include
exterior and interior models with either manual or motorized
operation. This guide specification section can be used to
specify Skyshield 90 as manufactured by Skyshield International,
Inc. Skyshield 90 is designed for installation on interior side
of medium and large size rectangular skylights and window
openings. Contact Skyshield International, Inc. for assistance
in specifying other Skyshield models.
The
specification section is organized by placing information in
three standard parts:
PART
1 - GENERAL Describes administrative and procedural
requirements.
PART
2 - PRODUCTS Describes materials, products, and accessories to
be incorporated into the construction project.
PART
3 - EXECUTION Describes how the products will be installed at
the construction site.
Throughout
this product guide specification, references are made to other
specification sections that might be contained in the project
manual. These references are presented as examples and
coordination reminders. For each project, these references will
need to be revised to reflect actual sections being used.
Within
the specification text, Imperial dimensions are presented first
in brackets followed by System International Metric (SI)
equivalents also in brackets. Depending on project requirements,
either the Imperial or the SI metric equivalents will need to be
deleted.
The
specifier will need to edit this product specification for a
specific project to reflect the options and applications being
used. The guide section has been written so that most editing
can be accomplished by deleting unnecessary requirements and
options. Depending on project requirements, some additional
information will need to be added by the specifier. Options are
indicated by [ ]. Notes to assist the specifier in selecting
options and editing the specification guide are printed in bold
and indicated with *****. For final editing, all brackets and
notes will need to be deleted from the guide.
