How it works

Power Floor is a resilient and fire-resistant precast concrete subfloor that solves the challenges of building with plywood and poured concrete floors.

WHY BUILDING OWNERS CHOOSE POWER floor

Power Floor provides simplicity and speed of construction for contractors, long-term durability and lower lifecycle costs for owners, and supreme comfort for building occupants.

COMPARISON TO TRADITIONAL SUBFLOOR SYSTEMS

Simpler and faster construction, superior performance 

Comparison to Traditional Wall Cladding Systems

Fewer steps, fewer failure points, better durability.

Plywood

WEAK POINTS

Combustible assembly
Poor acoustic separation between floors
Susceptible to moisture damage
Floor vibration and deflection
Additional layers for fire and sound performance

AAC ADVANTAGE

Non-combustible and fire-rated option
Higher mass improves sound reduction
Moisture-resistant - will not rot, warp, or swell
Greater rigidity and mass improve occupant comfort
Solid substrate for final floor finishes

Plywood and lightweight gypsum concrete

Weak Points

Multiple installation steps
Extended construction schedule
Susceptible to cracking and surface damage
Added weight
Moisture-sensitive

AAC ADVANTAGE

Single installed layer
No wet trades or curing time
Durable substrate
Predictable panel weight simplifies structural coordination
Improved fire resistance

Metal pan deck and concrete

Weak Points

Significantly higher cost
Multiple trades required
Concrete pour adds time and coordination costs
More difficult penetrations and floor modifications
Higher structural loads

AAC ADVANTAGE

Avoids concrete pours
Simpler construction and faster timeline
Installed by framing trades
Concrete-like mass and fire resistance without the additional weight

TYPICAL ASSEMBLIES & INSTALLATION

AAC Power Floor panels are placed over structural framing and mechanically fastened to the supporting members. Panel joints are bonded with thin-bed adhesive to create a continuous, rigid floor surface. The dry installation process eliminates concrete pours and curing time, allowing finishes to be installed shortly after placement.
