General Spec Question
The CSI MasterSpec is generally organized around materials. However there are many examples of building products that have more than one material (and are not Division 06 composites).
Take an aluminium window which comes pre-glazed in the factory. Does the whole window fall under the same Section in Division 08, including the glass? Another example is a architectural precast concrete sandwich panel with embedded rigid insulation. Is the whole panel, including insulation, specified in Division 03? Or does the insulation fall under Division-07?
Basically, are specs organised according to what is assembled on site versus what comes to the site pre-assembled? If something is pre-assembled, then all the materials used to make the product are included in one Division/Section only, correct?
I've been reading a lot and I find that I still get confused about this, probably because I've never been involved in specifying. At this point I think the only way I can be certain about this is by asking someone experienced.
Please help! I'd really appreciate it.

You are very close to getting it. Composites are typically materials that are can of “mixed up” for example Alucibond panels fit right here as you see that is one material in a whole assembly. Windows and glass do fall both on division 08 but in different sections. There is a section for aluminum windows and another section dedicated to glasss, even the glass in door panels. There is also a decorative glass section. I recommend you download the CSI index of sections to get a better understanding on what goes where.

I have done specifications for many projects. Here is my experience:
Each material will be at its own division, but will be referred to in the other section. For example, an aluminum window or storefront which comes pre-glazed in the factory, will be mentioned in the storefront division, but referred back to its own section:
Glazing: As specified in Division 08 Section “Glazing”.See a portion of the Kawneer specifications and you’ll understand:
1.1 “Storefront Framing System
EDITOR NOTE: CHOOSE ENTRANCE FRAMING TYPE BASED ON PROJECT REQUIREMENTS.
A. Storefront Entrance Framing:
1. Trifab™ VG 450/451/451T or Trifab™ 451UT.
2. Trifab™ 601/601T/601UT.
3. Thermally Broken Entrance Framing - Kawneer IsoLock™ Thermal Break with a 1/4" (6.4 mm) separation consisting of a two-part chemically curing, high-density polyurethane, which is mechanically and adhesively joined to aluminum storefront sections.
b. Thermal Break shall be designed in accordance with AAMA TIR-A8 and tested in accordance with AAMA 505.
B. Non-Brackets and Reinforcements: Manufacturer's standard high-strength aluminum with nonstaining, nonferrous shims for aligning system components.
C. Fasteners and Accessories: Manufacturer's standard corrosion-resistant, nonstaining, nonbleeding fasteners and accessories compatible with adjacent materials. Where exposed shall be stainless steel.
D. Perimeter Anchors: When steel anchors are used, provide insulation between steel material and aluminum material to prevent galvanic action.
E. Packing, Shipping, Handling and Unloading: Deliver materials in manufacturer's original, unopened, undamaged containers with identification labels intact.
F. Storage and Protection: Store materials protected from exposure to harmful weather conditions. Handle storefront material and components to avoid damage. Protect storefront material against damage from elements, construction activities, and other hazards before, during and after storefront installation.1.2 Glazing
A. Glazing: As specified in Division 08 Section “Glazing”.
B. Glazing Gaskets: Manufacturer's standard compression types; replaceable, extruded EPDM rubber.
C. Spacers and Setting Blocks: Manufacturer's standard elastomeric type.”You can see the complete specifications at the manufacturer’s website at this link:
