Our customers can choose from a full range of aerated concrete products under our high-profile YTONG brand. This modular building shell system comprises small and large aerated concrete elements which are perfectly coordinated from the cellar to the roof and are easy to use. Aerated concrete from XELLA offers the best possible solution for any application in terms of technology, economy and ecology.
Under the brand name YTONG we offer numerous products in a whole variety of sizes and formats. Our most important and best-selling building materials are briefly outlined below. Not all materials are available in all countries, as construction practices differ from one country to the next. Visit the XELLA website for your country to find out which materials are available in your country. The most comprehensive product presentation can be found on the website for our domestic market Germany at www.xella.de
YTONG Thin joint block
This block is a standard product which is produced in various sizes, formats and bulk densities. The outstanding thermal insulation by air trapped in millions of minute pores is a characteristic feature. The requirements imposed by the German regulation on energy conservation (EnEV) are easily met with a thermal insulation value of up to lambda 0.09 W/(mK). Other properties of this material include the high load-bearing capacity of solid blocks with a robust supporting frame to bear loads from all sides, as well as outstanding protection against fire. YTONG flat blocks can be used for fire walls. Pockets cut into the block allow these blocks to be laid ergonomically, as well as quickly and easily on a thin mortar bed thanks to large formats with tongue and groove. Blocks can easily be cut to the required size with a saw. Further advantages: YTONG flat blocks provide an ideal base for attachment without cavities, permit optimum surface treatment through homogeneous, level wall surfaces and good noise protection. YTONG aerated concrete is made from natural raw materials – sand, lime, cement, water and a small amount of sponging agent (powdered aluminium).
Data sheet
YTONG flat building board
Solid partition walls with little own weight can be erected quickly and easily using YTONG flat building board. The YTONG flat building board is similarly characterised by outstanding protection against fire and also by good noise protection due to the advantageous pore structure. Handy large formats are easily processed using thin mortar beds. Blocks can simply be cut to fit with a saw. Homogeneous, level walls permit optimum surface treatment of the flat building boards, which simultaneously provide an ideal base for attachment without cavities.
YTONG System W wall element
YTONG System W wall elements are very large with lengths of more than 7 metres. Their width and height depend on the purpose for which the wall elements are used. These wall elements allow the building work to proceed very rapidly with little personnel required. Planning of the buildings is based on optimised parts using the planning grid for System wall elements, thus reducing the risk of potential building errors. The physical building properties of the wall elements correspond with those of the tried-and-tested YTONG flat block.
YTONG Jumbo W flat elements
Our Jumbo flat elements are used for load-bearing and non-load-bearing external and internal walls, reinforcing walls, basement walls and infill walls. These flat elements are also available in various formats. All are characterised by the typical YTONG properties, such as excellent thermal insulation and outstanding protection against fire. The flat elements provide an ideal base for attachment without cavities and permit rapid processing with thin-bed mortar. A mini-crane is useful for erection. Homogenous, level wall surfaces with few joints permit optimum surface treatment.
YTONG W ceiling board
Reinforced YTONG ceiling boards have proved ideal for basement ceilings and intermediate ceilings in single-family, duplex and terraced houses. They are laid quickly and simply with the aid of a crane. With no complex or time-consuming formwork required, the YTONG floor can immediately be subjected to loads and walked over, thus guaranteeing rapid progress in building work. The ceiling boards are non-flammable and suitable for all types of flooring. Even solid roofs can be produced with these ceiling boards. YTONG ceiling boards come in standard lengths of 6 metres, but lengths of up to 8 metres are also possible. The ceiling boards are available in widths of 62.3 cm and more, as well as in a thickness of 20 cm or more.
YTONG W roof boards
If the roof space is to be used for living purposes, the YTONG solid roof is of decisive advantage by ensuring a balanced room climate. Particularly the statutory requirement for wind-tightness imposed by the German EnEv regulation can easily be met with this material. YTONG roof and ceiling boards can be laid directly from the truck on the prepared masonry. This is possible up to a roof angle of < 15°. The roof boards for roofs sloping at an angle of more than 15° are fitted with transport anchors. The roof boards of reinforced aerated concrete come in standard lengths of 6 metres, but lengths of up to 8 metres are also possible. The roof boards are available in widths of 62.3 cm and more, as well as in a thickness of 20 cm or more.
YTONG U-block
YTONG U-blocks are formwork blocks for efficient production of concrete joists, lintels and stiffeners, etc. Edge formwork is not necessary when using these U-blocks; all they need is a continuous substructure of planks or boards. Additional local support is only necessary when spanning openings more than 1.25 m wide. YTONG U-blocks are laid quickly and easily in a thin mortar bed. They can easily be cut to any required length.
YTONG W lintel
Reinforced YTONG lintels are available to span openings in load-bearing and non-load-bearing walls. The YTONG W lintel (load-bearing) is characterised by its high load-bearing capacity. Formwork is not needed. The lintel is laid quickly and easily in a thin mortar bed and can immediately be subjected to loads. Supports are not required. There is no need to change materials when finishing the surface, since the same plaster base is involved. The YTONG W lintel (non-load-bearing) is used in non-load-bearing walls. It too does not require a support and the bricklaying work can continue directly.
