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.

No. AAC construction provides a solid, monolithic wall system with an enclosed, non-connected cellular structure. Exterior finishes are designed to complement this structure, providing a healthy balance between moisture resistance and vapor diffusion. The positive pressure of the air conditioning system pushes water vapor out through the walls, while preventing moisture penetration from the outside.

Many of the conventional exterior finishing systems such as one coat plastering (sometimes referred to as a hard coat system) and two coat systems can be used over Ytong AAC as an exterior finish. Other options such as brick veneer, stone and siding can be used and have been used in many residential projects.

The location of the vapor barrier depends on the climate. For homes in Florida, we do not recommend a vapor barrier, but highly recommend a rain barrier and an air infiltration barrier. In Florida, nailing on paper (which is black tar paper) backed lath to cdx and then stuccoing over it and then painting with elastrometric paint works well. Don't need to paint cdx. The best way to dispel the heat is to block the direct solar radiation before it gets to the window.

No vapor barrier is necessary in a 12" thick clay/straw wall. Clay has the ability to hold many times its weight in moisture without deteriorating. It has the ability to wick water away from wood and straw and to release the moisture back into the air when the ambient air humidity drops. The clay itself acts as a huge network to intercept, hold and then release moisture in the first couple of inches of the wall so that no significant amount of moisture ever penetrates to dew point.

Ytong AAC is probably the safest building product available. Ytong AAC is a non-toxic product that does not pollute the air, land or water. During the manufacturing process, waste from the cutting process is recycled back with raw materials and used again. During construction, there is virtually no waste generated. Ytong AAC products were designed to respond to the urgent need to conserve and protect the earth's precious natural resources.

No. Ytong AAC was first commercially produced in 1923 in Sweden. Since then, Ytong AAC construction systems such as masonry units, reinforced floor/roof and wall panels and lintels have been used on all continents and every climatic condition.

Standard elastomeric paint, traditional or synthetic stucco, thin brick facing, tile, siding materials or any other building finish can be used on the outside of Ytong AAC walls. Inside, Ytong AAC walls can be finished with plaster, textured paint, gypsum drywall or any other interior finish.

The selection and/or location of a vapor retarder is project specific based on numerous factors including climate, wall components, etc., and as such is a design consideration that is the responsibility of the design professional.

No. To be classified as a water vapor barrier, the product must have a permeability rating of 1.0 or less. Fullback has a permeability rating of 5.0 which is up to 500% better than most flat foam insulation panels. I just had Fullback installed, but it doesn't feel solid like the sample did. I can feel places that do not seem to have anything behind it. If the sample was flat on a table when you pushed on it, it would feel solid.

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.

Easily. People often imagine that wiring will be a challenge due to the solid structure of Ytong AAC blocks. When they discover how versatile and workable Ytong AAC really is, they are pleasantly surprised. There are 2 standard methods for installing wiring in Ytong Autoclaved Aerated Concrete walls. Many installers use a combination. Routing: Build the walls first. The electrician draws directly on the block to indicate where the wires will go.

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.

Ventilation is not required, but it is extremely helpful when addressing convective heat transfer. If an attic system has a mass insulation, (such as fiberglass), a Radiant Barrier and a ridge vent, it has addressed all three types of heat flow; conductive, convective and radiant.

The panel itself serves as the vapor barrier. Most model building codes require a vapor barrier with a perm rating of 1 or less. The perm rating of the Universal Foam Tech, Inc. system is less than 1. Moreover, with the Universal Foam Tech, Inc. system wall, voids are eliminated and therefore moisture does not condense. Moisture is not a problem with this panelized system.

Many of the high-end grills are shipped completely assembled. Check with your salesperson to be sure about the one you order.

Ytong Autoclaved Aerated Concrete (Ytong AAC) is well known as an environmentally friendly construction material. The production of Ytong AAC requires only a fraction of the energy compared to other materials. The manufacturing process emits no pollutants and creates no by-products or toxic waste products. Ytong AAC is manufactured from common and abundant natural raw materials.

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.
