When you invest in a new home or commercial building, safety is the ultimate priority. In areas prone to wildfires or where insurance premiums are sensitive to building materials, achieving a superior fire rating is non-negotiable.
At Prefab1, the best ADU company, our commitment to safety is built into the core structure of every modern prefab ADU and modular commercial construction project we deliver. This commitment begins and ends with Cold Formed Steel (CFS) Framing, the key to achieving a robust, non-combustible defense against fire.
1. What is Class A Fire Resistance?
In construction, a Class A rating is the highest possible fire rating, meaning the material has the lowest possible flame spread index. This classification indicates that the material will not contribute fuel to a fire, which is crucial for protecting the structure and, most importantly, the occupants inside.
Traditional wood framing, which can ignite at temperatures as low as , simply cannot compete. Our steel frame ADU construction, however, is inherently non-combustible.
2. The Non-Combustible Advantage of CFS
Cold Formed Steel is steel—an inorganic material that cannot burn. Its melting point exceeds , far hotter than the typical residential fire, which rarely exceeds .

CFS Fire Safety Benefit |
Why This Matters to Your Investment |
|---|---|
|
Non-Fuel Source |
The structural frame will not contribute to the fire load, slowing the spread and containing the fire to its point of origin. |
|
Life Safety |
Slower fire spread gives occupants crucial extra time to evacuate safely, which is the primary goal of any fire code. |
|
Lower Insurance Costs |
Due to the reduced risk of structural fire damage, many insurance providers offer significant premium discounts for steel frame ADU owners. |
|
Structural Integrity |
Unlike wood that collapses as it burns, the CFS frame maintains its integrity far longer, reducing the risk of total structural failure. |
3. Engineering a Fire-Resistant System
Achieving total fire resistance goes beyond the steel itself. Our luxury prefab homes are designed as integrated, fire-resistant systems:
-
Code Compliance: Our designs are engineered to meet and often exceed the most stringent fire-resistance standards set by national and regional building codes.
-
Integrated Materials: The combination of the CFS frame with surrounding gypsum board and non-combustible exterior wall panels creates fire-rated assemblies that dramatically increase containment time.
