DOT and Site Walls

Hebel AAC has a Sound Transmission Coefficient (STC) value of 50 for an AAC4, 8” thick unfinished wall. This STC, combined with Hebel’s lighter weight than traditional concrete masonry, makes AAC a perfect choice for highway and site walls. Hebel AAC is more durable than traditional corrugated metal walls. With a compressive strength of 580 psi, AAC walls combined with a finish coating will withstand the harsh conditions incurred by DOT better than its metal-based competitor.
