The organization called AWI (Architectural Woodwork Institute) sets the standards for quality and craftsmanship in the millwork industry. These guidelines serve as a benchmark for architects, contractors, and woodworkers.
Think of these standards as a set of rules that help maintain high quality across all woodwork projects. They make sure the finished product is not only beautiful but also durable and functional. These standards provide consistency and excellence in the production of custom wood products like cabinetry, trim, and other interior finishes.
In these standards, AWI outlines the best practices for delivering top-quality architectural woodwork. These standards are designed to guide woodworkers, contractors, and architects to ensure that the result meets the expectations of quality, aesthetics, and functionality.
There are nine AWI standards in total, which we will be discussing in this guide. AWI standards cover every stage of the millwork process, from the design and selection of materials to fabrication and installation.
Let’s begin!
History Of AWI Standards
In 1961, AWI released its first set of guidelines called “Quality Standards.” These rules covered how to make and install different wood products. Over time, these guidelines became more detailed, covering everything from materials to finishes.
As woodworking techniques and technology improved, AWI kept updating its standards. In 2003, AWI introduced the “Architectural Woodwork Standards” (AWS), which expanded on their earlier guidelines. AWS brought together several different industry groups, making the standards more widely accepted.
Now in the 2010s, AWI introduced a performance-based approach to their standards, meaning they focused more on how well the finished product functions rather than just how it looks. This shift helps that woodwork not only looks good but also performs well over time.

AWI 100 – Submittals
AWI 100 is the starting point for any millwork project, focusing on the submittals required before the work begins. Submittals are documents that provide essential information to all parties involved in the project, such as architects, contractors, and clients.
These documents confirm that everyone is on the same page before fabrication or installation begins.
Components Of AWI 100
- Shop Drawings: These are highly detailed blueprints that showcase the design, construction methods, materials, and installation of millwork elements. They help verify that the woodwork is fabricated according to project specifications.
- Product Data: This includes detailed specifications of materials such as the type of wood, finishes, hardware, and other components used in the project. It provides insight into the quality and aesthetic expectations.
- Samples: Physical examples of materials and finishes are provided to illustrate the exact look and feel of what will be installed.
- Approvals: This stage involves stakeholders reviewing and approving the shop drawings, material data, and samples. The approval process guarantees that the design intent and material specifications meet project expectations.
Best Practices
- Always submit accurate and detailed shop drawings to make sure they match the architectural design.
- Submit material samples as early as possible to allow sufficient time for review and approval.
- Consistently communicate with all stakeholders during the submittal process to avoid misunderstandings and delays.

AWI 200 – Care & Storage
AWI 200 provides critical guidelines for the proper care and storage of wood materials throughout a project’s lifecycle. Wood is a natural material that reacts to environmental changes. This makes it vulnerable to issues like warping, splitting, or moisture absorption if not handled correctly.
This standard guarantees that wood maintains its integrity and quality from the moment it is received until installation is complete.
Components Of AWI 200
- Environmental Controls: AWI 200 outlines specific requirements for maintaining optimal temperature and humidity levels to protect wood from environmental damage. These controls help prevent issues like warping, swelling, or drying out caused by extreme or fluctuating conditions.
- Storage Practices: Proper storage methods are emphasized, including recommendations to store wood in climate-controlled environments. This assures the materials remain stable and unaffected by external conditions, preserving their quality before installation.
- Handling Guidelines: Careful handling of wood materials is essential to prevent physical damage. AWI 200 provides guidelines on how to transport and handle wood safely, reducing the risk of scratches, dents, or other structural defects during the moving and installation process.
Best Practices
- Store wood in climate-controlled conditions to protect it from environmental changes.
- Acclimate wood products to the project environment before installation to prevent dimensional changes once installed.
- Follow recommended handling procedures to avoid accidental damage during transport and installation.

AWI 300 – Materials
AWI 300 sets the standard for selecting materials used in architectural woodwork. With the help of these standards, woodworkers choose the best-suited materials for each project based on factors like durability, aesthetics, and functionality. This standard helps that the finished product not only meets design expectations but also performs well under various conditions.
Components Of AWI 300
- Lumber: AWI 300 covers the selection of both hardwoods and softwoods for different applications. Hardwoods like oak, maple, and cherry are often chosen for their strength and visual appeal, while softwoods like pine may be used in less demanding applications.
- Sheet Goods: This includes specifications for materials like plywood, MDF (medium-density fiberboard), and high-pressure decorative laminates (HPDL). These materials are often used for cabinetry, paneling, and other woodwork due to their versatility and stability.
- Veneers: AWI 300 guides on selecting wood veneers based on characteristics such as grain pattern, color, and overall quality. Veneers offer a way to achieve a high-end appearance while using less expensive core materials.
Best Practices
- Use strong, durable hardwoods in high-traffic or high-impact areas for longevity.
- Choose materials with moisture and environmental resistance, especially in areas exposed to humidity or temperature changes.
- Select veneers carefully to confirm color consistency and grain matching for a polished, professional look.

ANSI/AWI 0400 – Factory Finishing
ANSI/AWI 0400 provides guidelines for the factory finishing of wood products, providing a controlled process for applying finishes such as stains, varnishes, and sealants.
By completing the finishing in a factory setting, the standard provides a higher level of consistency and quality, as environmental factors like dust, humidity, and temperature are closely regulated.
Components Of ANSI/ AWI 0400
- Finishing Techniques: This standard covers various types of finishes, including lacquer, varnish, and water-based coatings, each chosen based on the project’s aesthetic and durability requirements. The right finish improves both the appearance and protection of the wood.
- Surface Preparation: ANSI/AWI 0400 focuses on the importance of thorough surface preparation before applying any finish. Sanding and priming the wood confirms that the surface is smooth and ready for an even, high-quality application of the finishing material.
- Performance Characteristics: The finishes must protect the wood from environmental factors such as moisture, wear, and damage over time. This provides the longevity and durability of the wood, making it suitable for various applications, from furniture to architectural woodwork.
Best Practices
- Selecting the right finish for durability and long-term protection is essential. This provides the wood is shielded from damage and retains its look over time.
- Before applying any finish, make sure that all surfaces are carefully sanded and primed to avoid any imperfections or uneven coatings.

Summary
In summary, the Architectural Woodwork Institute (AWI) sets essential standards for quality in the millwork industry to ensure that wooden features like cabinetry and trim are both beautiful and durable.
First introduced in 1961 as “Quality Standards,” these guidelines have evolved into the “Architectural Woodwork Standards” (AWS), focusing on both appearance and performance. In the modern era, AWI set up the nine prominent standards for the millwork industry.
AWI 100, AWI 200, AWI 300, ANSI/AWI 0400, ANSI/AWI 0620, ANSI/AWI 0641, ANSI/AWI SMA 0643, ANSI/AWI 1232, and ANSI/AWI 1236 are these nine standards. These standards collectively assure that architectural woodwork projects are completed with high quality and consistency.
