Ecolite Ytong AAC wall, floor and roof systems provide an innovative combination of excellent low thermal conductivity, thermal mass and low air-infiltration. This practical combination of properties in one system provides an excellent thermal insulation material and permits peak energy usage in the building to be shifted to off-peak hours, thus reducing operation cost for building users and owners, improving comfort of living and reducing the demand on power generation facilities.

The thermal performance of AAC is equivalent to R-20 insulation. AAC combines the advantages of low thermal conductivity and low air-infiltration with high thermal mass. This product is used in every climatic region of the world, from humid South America, to the dry heat of the Middle East and the severe cold of Finland. Insulation is rarely added; the walls are simply thicker. For more information on thermal performance testing, please see our Energy Efficient page. See similar questions...

The "effective date" applies to the Federal Register final rule. It is a 30-day period after which the changes officially become a part of the National MUTCD. The "adoption date" applies to Title 23, Code of Federal Regulations (CFR), Part 655.603, which provides States 2 years from the effective date to adopt the changes in the National MUTCD. For example, the final rule for the 2003 MUTCD was published in the November 20, 2003 Federal Register. See similar questions...

R-value is an assigned number derived from a specific testing procedure to determine a materials (or building assemblage) "resistance to conductive heat transfer". The higher the R-value, the more resistant a material (or building assemblage) is to conductive heat transfer. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

Ytong AAC outperforms concrete and wood. Ytong AAC is the only durable, structural, thermal and fire rated material all in one product. For example, in wood construction, insulation and drywall must be added to make the wall fire rated and thermally compliant. In addition, insulation must be added to masonry to obtain reasonable thermal values. See similar questions...

a non-organic mineral based material, Ytong AAC products do not promote the growth of mildew and molds. Mildew may appear over finishes if material used for finishing promotes the growth of mildew. See similar questions...

Fasteners are available that easily drive into Ytong AAC walls and are capable of securing heavy items. These fasteners are similar to standard concrete "spread-fast" anchors. Since Ytong AAC is less dense than standard concrete, fasteners can be driven in with a hammer. Specialty drills are not required. Unlike stud walls, fasteners can be placed anywhere in Ytong AAC walls. No need to explore to find studs for hanging heavy objects. See similar questions...

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. See similar questions...
