solid monolithic Ytong AAC wall system, the enclosed non-connected cellular structure and exterior finishes provide the healthy balance between resistance to moisture penetration and vapor diffusion. This balance is adequate to maintain a dry system, prevent moisture condensation and allows vapor diffusion when and if any presence of vapour occurs within the wall system.

The structural span for floor/roof and wall panels depends on the live and dead loads and the thickness of the panel. for wall panels, the maximum structural span depends on the design load and thickness of panels. However, wall panels can be designed for almost all design loads typically required by national design codes.

Metallic glazes were designed for interior use. If several coats of McCloskey Man O War Marine Spar Varnish are used, exterior applications are possible. Please note that Spar Varnish is very yellow/amber in color and may change the look of some colors.

Ytong AAC has proven to be a very durable material. There are numerous structures in many different climates worldwide, many over 75 years old, in excellent condition. Ecolite Ytong AAC will not rot, warp, rust, corrode, or otherwise decompose. Termites and other pests do not eat it. Ytong AAC will not burn. The millions of tiny cells in Ytong AAC cushion buildings from major force, preventing progressive collapse.

All commercial available roofing systems can be used over Ytong AAC roof. Generally speaking, when Ytong AAC roof panels are used flat or near flat, they are covered with a membrane system such as built-up or EPDM. On a pitch, they are often covered with concealed fastener metal roofs or shingles.

Exterior masonry facing materials are compatible with am-cor? construction. am-cor? frame panels can be supplied with brick clips at 2'-0" o/c. While the unified cement coating is preferred for durability and appearance, cement board siding may be applied using self-tapping bugle head screws supplied with your am-cor? PAK.

Yes, in fact it will last longer. The durability of Ytong AAC has been proven in every type of climate in the world for over 75 years.

Almost never. Ecolite Ytong AAC walls are insulated by millions of tiny air cells which reduce thermal conductivity. The thick walls also benefit from high thermal mass, much like a log home.
