Building Smarter: How Fire Retardant Treated Wood Supports Multifamily Housing Success
When it comes to building safe, cost-effective, and code-compliant multifamily structures, fire treated wood (FRTW) stands out as a go-to solution for contractors and developers alike. From apartment complexes to townhomes, fire treated wood in multifamily housing offers the ideal blend of performance and peace of mind.
Let’s explore the top reasons builders continue to rely on FRTW in apartments and similar multi-unit residential projects.
What Is Fire Treated Wood (FRTW)?
FRTW is dimensional lumber or plywood that’s been pressure-treated with fire-retardant chemicals. This treatment helps limit flame spread, reduce smoke development, and increase resistance to ignition. It’s especially valuable in densely populated residential buildings where fire safety is critical.
Why Builders Use Fire Treated Wood in Multifamily Housing
1. Meets Building Code Requirements
Multifamily buildings often fall under stricter fire safety regulations. Using fire treated wood in multifamily housing allows builders to meet International Building Code (IBC) and National Fire Protection Association (NFPA) standards, particularly in Type III and Type V construction.
2. Improves Fire Resistance in Key Areas
FRTW is commonly used in:
- Party walls between units
- Roof and floor assemblies
- Stairwells and corridors
- Exterior walls near lot lines
3. Cost-Effective Alternative to Non-Combustible Materials
Compared to steel or concrete, FRTW provides an economical option while still satisfying code requirements. It reduces material costs and speeds up installation without compromising on safety.
4. Lightweight and Easy to Install
FRTW is easier to handle, cut, and fasten than non-combustible materials. This makes construction faster and less labor-intensive—key benefits in large-scale apartment builds where timelines matter.
5. Peace of Mind for Developers and Tenants
With fire treated wood in place, developers know they’re offering a safer structure, while residents benefit from enhanced fire resistance and better overall building protection.
Common Multifamily Applications for FRTW
- Interior unit separation walls
- Roof trusses & rafters
- Floor & roof joists
- Plywood roof, wall and subfloor sheathing
- Mezzanines
- Sill plates
- Steps and stairways
- Interior and exterior wall studs
- Partition walls
- Beams and purlins
- Temporary platforms or structures
- 1 & 2 hour fire-rated wall assemblies
- Furring, blocking and backing
Final Thoughts
In the world of high-density residential construction, safety and efficiency are non-negotiable. That’s why more and more builders are choosing fire treated wood for multifamily housing. From meeting codes to simplifying installation, FRTW in apartments delivers real value at every stage of construction.
