SECTION 08622
TUBE SKYLIGHT
***** Active Ventilation Products, Inc. manufacturers passive and powered exhaust ventilators, tube skylights, and combination skylight and ventilator units.
This guide can be used to prepare a specification for Aura Skylight, a compact, tubular, roof mounted skylight with ceiling light diffuser.
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. 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.

A. Coordinate provision of skylight with:
1. Roof system specified in Section [_____] - [_____] to ensure compatibility of substrate to receive skylight.
2. Ceiling system specified in [Section 09260 - Gypsum Board Assemblies] [Section 09510 - Acoustical Ceilings] to ensure proper mounting of ceiling assembly.
B. Examine site conditions and verify that structural supports and openings are properly sized, prepared, and ready to receive skylight.
