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.  The most comprehensive product presentation can be found on the website for our domestic market Germany at

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 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).

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.

Basic material

Thanks to its characteristic structure comprising millions of tiny pores, it offers optimum solidity at low weight. As air has a low heat conductivity, aerated concrete provides for excellent thermal protection. It protects from cold and heat, allowing for single-shell constructions which provide more space, save time and reduce costs-aspects which are of considerable importance to property developers.


Aerated concrete is made from natural raw materials – sand, lime, cement and water – with an aerating agent.



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.
