Why build with AAC
Autoclaved aerated concrete is a lightweight, cured masonry made from sand, cement, lime and water. It's designed for durability, versatility and fast-track construction.
What AAC gives you
One material handles structure, insulation, fire protection and sound control, so there are fewer layers and fewer trades.
Lower energy costs
Insulating, airtight walls with thermal mass keep Texas heat out and cooling loads down. An 8-inch wall rates about R-11.
4-hour fire rating
AAC is non-combustible, with UL-rated assemblies up to four hours.
Shorter build times
Large, light units are cut on site with hand tools and set with thin-set mortar, which reduces labor.
Termite and mold resistant
It's inorganic, so there's nothing to rot or feed pests.
Less steel
Its light weight can reduce structural steel and foundation requirements.
Earth-friendly
Low-energy manufacturing, little site waste, and offcuts that can be recycled.
AAC compared
A general comparison of common wall systems. Actual performance depends on the assembly and design.
| Property | AAC block or panel | Concrete block (CMU) | Wood frame |
|---|---|---|---|
| Weight | Light; easy to handle and ship | Heavy | Light |
| Fire | Non-combustible; up to 4-hour rating | Non-combustible; rating varies by unit | Combustible; rating depends on added gypsum layers |
| Insulation | Built in; about R-11 at 8 inches, plus thermal mass | Needs added insulation | Depends on cavity fill and air sealing |
| Sound | Solid, dense wall dampens noise | Good | Needs added treatment |
| Pests and moisture | Inorganic; won't rot or feed termites | Inorganic | Vulnerable to termites, rot and mold |
| Trades for the shell | One crew for structure and insulation | Mason, then insulation | Framer, sheathing, insulation, wrap |
How an AAC wall goes up
Level the first course
Set in a full mortar bed on the slab, perfectly level.
Thin-set and stack
Blocks are bonded with thin-set mortar in a running bond.
Reinforce
Rebar and grout in cores and bond beams per engineering.
Finish
Stucco or veneer applied directly, no lath needed.
