In construction project specifications and documentation, windows are categorized under Division 08 of the Construction Specifications Institute's (CSI) MasterFormat®.
Understanding CSI MasterFormat
The CSI MasterFormat is a widely used standard for organizing specifications and other written information for commercial and institutional building projects in the U.S. and Canada. It provides a uniform system of numbers and titles for organizing information into a hierarchical structure, making it easier for architects, engineers, contractors, and manufacturers to communicate and find information.
The MasterFormat is divided into broad Divisions, which are further broken down into Sections. Each Division represents a major category of work or materials.
Windows and Doors: Division 08
As specified in the reference provided, windows fall under Division 08 - Windows and Doors. This division encompasses a wide range of products and associated work related to openings in buildings, primarily focusing on fenestration (windows, curtain walls, skylights) and entries (doors, frames, hardware).
What Does Division 08 Cover?
Division 08 is comprehensive, covering various aspects of windows and doors. Key elements typically included in this division are:
-
Windows:
- Different types of windows (e.g., casement, double-hung, sliding, fixed)
- Window materials (e.g., vinyl, aluminum, wood, fiberglass)
- Glass types (e.g., insulated, low-E, tempered)
- Window hardware and accessories
- Window installation requirements
-
Doors:
- Various door types (e.g., swinging, sliding, overhead)
- Door materials (e.g., wood, metal, glass)
- Door frames and assemblies
- Door hardware (e.g., hinges, locks, closers, exit devices)
-
Related Products:
- Curtain walls and storefront systems
- Skylights and roof windows
- Screens, blinds, and shutters
- Specialty doors (e.g., security doors, fire-rated doors)
Organizing this information under a single division helps ensure that all components related to windows and doors are specified together, simplifying the bidding process and project management.
Example CSI MasterFormat Sections in Division 08
While the MasterFormat is updated periodically, here are some common types of sections you might find within Division 08:
| Section Number (Example) | Description |
|---|---|
| 08 11 00 | Metal Doors and Frames |
| 08 14 00 | Wood Doors |
| 08 41 00 | Curtain Walls |
| 08 51 00 | Metal Windows |
| 08 52 00 | Wood Windows |
| 08 53 00 | Vinyl Windows |
| 08 71 00 | Door Hardware |
| 08 80 00 | Glazing |
| 08 90 00 | Louvers and Vents |
Note: Section numbers and titles can vary slightly based on the specific edition of MasterFormat used and project specifics.
Using this standardized structure ensures clarity and consistency in construction documentation, making it easier for everyone involved in a project to locate and understand the specifications for windows and related elements.
