AAC MASONRY

How it works

AAC masonry is your building’s structure, envelope, insulation, sound reduction, fire safety, and windstorm protection all in one system.

WHY BUILDING OWNERS CHOOSE AAC MASONRY

Owners choose AAC block masonry for its resilience, safety, healthy indoor environments, superior performance, lower lifecycle cost, and longer life cycle.

DURABILITY

Eliminates foam plastic insulation
Non-combustible
Moisture & rot resistant

Pest resistant
Windstorm protection

PERFORMANCE

Continuous insulation
Thermal mass
High sound reduction
No mold or mildew

Healthier indoor environment

LOWER TOTAL COSTS

Single integrated system
Installed by one trade
Eliminates steps and layers
Lower energy costs

Reduced maintenance
Lower insurance costs

WHERE AAC MASONRY IS USED

Used as an upgrade to conventional framing or a more cost-effective alternative to concrete masonry (CMU), insulated concrete form (ICF), and concrete tilt panel construction.

COMPARISON TO TRADITIONAL WALL SYSTEMS

AAC block masonry eliminates the complexity of multi-layer wall systems by integrating performance into a single material—delivering faster construction, greater durability, and lower total cost of ownership.

Comparison to Traditional Wall Cladding Systems

Fewer steps, fewer failure points, better durability.

Conventional Light Framing (wood and steel)

WEAK POINTS

Complex assemblies that are more prone to errors

Lower energy efficiency performance

Vulnerable to moisture, fire, windstorms, and pests

Issues with mold and mildew

Reduced sound reduction

AAC ADVANTAGE

Up to 250% higher than energy code

Highest fire and windstorm safety ratings

Creates healthier and more comfortable indoor spaces

 Simplified construction with fewer layers and trades

Concrete Masonry Unit (CMU)

Weak Points

More difficult insulation options to meet energy code

Heavier and smaller units increase labor, time, and installation costs

Inflexible building system that limits design options

AAC ADVANTAGE

Integrated insulation reduces thermal bridging and improves energy performance

Single-material wall system simplifies design and construction

Larger, lightweight blocks increase installation speed and consistency

Reduced assembly weight

Insulated Concrete Form (ICF)

Weak Points

Multi-step installation (stacking, bracing, reinforcing, pouring, curing)

Requires skilled crews to avoid alignment and blowout issues

Material and labor costs can be high

Significant assembly weights

AAC ADVANTAGE

Faster, more straightforward installation with conventional masonry crews

No large concrete pour reduces risk, complexity, and schedule delays

Lower overall system cost with fewer trades and steps

Insulated Concrete Tilt Panel

Weak Points

Requires continuous insulation on the interior or exterior

Sandwich panel tilt wall very expensive

More difficult to cast panels on smaller projects

More limited architectural freedom

AAC ADVANTAGE

No additional steps for insulation

Meets energy and fire code without interior finishes

Lighter weight assembly

More flexible architectural design

TYPICAL ASSEMBLIES & INSTALLATION

AAC block walls are built by stacking these lightweight blocks and adhering with thin-bed mortar, then reinforcing where necessary with rebar and concrete, and finishing as required.

Installed by block masons
Single integrated system for structure, insulation, envelope
AAC blocks are easy to cut and shape as required
Construction drawings show precise locations for vertical and horizontal reinforcement
UL fire-rated assemblies available
