SECTION 12491 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 80 as manufactured by Skyshield International, Inc. Skyshield 80 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. *************************** PART 1 - GENERAL 1.1 SUMMARY ***** Skyshield 80 is designed for interior installation and can be either manually or electrically operated.
