The CSI code for wood siding is 07 46 23.
Understanding CSI MasterFormat for Construction Specifications
The Construction Specifications Institute (CSI) MasterFormat is a crucial organizational standard for the architecture, engineering, and construction (AEC) industry in North America. It provides a standardized numbering system and title structure for organizing construction project specifications, bidding requirements, and project costs. This comprehensive system ensures consistency and clarity across all phases of a building project, from initial design to procurement and construction.
The Specific MasterFormat Code for Wood Siding
Within this structured framework, wood siding is precisely identified by the MasterFormat code 07 46 23. This code falls under Division 07 – Thermal and Moisture Protection, a broad category that encompasses all materials and systems designed to control the flow of heat, air, and moisture within a building's envelope.
Here's a breakdown of how the code is organized:
- 07: This prefix signifies Division 07 – Thermal and Moisture Protection. This division covers a wide range of building components, including roofing, waterproofing, insulation, and various types of exterior siding.
- 46: This middle section of the code specifically identifies "Siding," categorizing all types of exterior cladding materials that protect a building's walls.
- 23: The final digits narrow down the classification to "Wood Siding," pinpointing this specific material type within the broader siding category.
This detailed classification allows for precise specification, procurement, and installation of wood siding materials, ensuring all project stakeholders are referencing the same information.
MasterFormat Breakdown for Wood Siding
| MasterFormat Level | Code | Description |
|---|---|---|
| Division | 07 | Thermal and Moisture Protection |
| Section | 46 | Siding |
| Specific Category | 23 | Wood Siding |
Why MasterFormat is Essential in Construction
Adopting MasterFormat codes, such as 07 46 23 for wood siding, brings significant advantages to the construction process:
- Enhanced Communication: Provides a common language for architects, engineers, contractors, manufacturers, and suppliers, reducing misunderstandings.
- Streamlined Project Management: Facilitates easier organization of project manuals, specification documents, and cost estimates.
- Improved Bid Accuracy: Standardized categories help contractors provide more consistent and accurate bids, simplifying comparisons.
- Efficient Material Procurement: Enables precise identification and ordering of materials, minimizing errors and delays.
- Legal Clarity: Creates a clear and defensible framework for contractual agreements and dispute resolution.

Common Types and Considerations for Wood Siding
Wood siding remains a popular choice for its natural beauty, versatility, and environmental benefits. Various profiles and species offer distinct aesthetic and performance characteristics:
- Clapboard (Bevel Siding): Horizontally installed, overlapping boards that create classic shadow lines.
- Shingles and Shakes: Smaller, individual pieces of wood, often cedar, providing a rustic and textured appearance. Shakes are typically hand-split for a rougher finish.
- Board and Batten: Wide vertical boards with narrower strips (battens) covering the seams, offering a strong vertical design element.
- Log Siding: Designed to emulate the look of a log cabin, available in various profiles like half-logs.
- Tongue and Groove: Boards with interlocking edges for a tight, smooth, and continuous surface.
When specifying wood siding, key considerations include:
- Wood Species: The choice of wood (e.g., cedar, redwood, pine) affects durability, resistance to pests and rot, and maintenance requirements.
- Finishes: Stains, paints, or clear sealers are essential for protecting the wood from weather and UV exposure while defining its visual appeal.
- Installation: Proper installation, including appropriate flashing, moisture barriers, and ventilation, is critical for the siding's longevity and performance.
- Maintenance: Regular cleaning, inspection, and re-application of finishes are necessary to preserve the wood's condition and appearance over time.
- Sustainability: Opting for sustainably harvested and certified wood products (e.g., FSC-certified) can contribute to a project's environmental goals.
