The development is distinguished by the optimal design of internal voids, which ensures high thermal performance, light weight and strength of the products. The use of Porotherm 51 GL helps to save on building a house as a whole, as it significantly reduces foundation costs.
“When developing a project, engineers strive to find the most optimal solution that will meet the requirements for thermal insulation and at the same time will reduce the final cost of construction. Especially for private houses, we have developed ceramic blocks Porotherm 51 GL, which, when laid in one row, form a structure with a total heat transfer resistance of 3.15 ° С ∙ m2/ W, which is 6-18% higher than that of analogs and exceeds the requirements of SNIP1… Such thermal characteristics allow Porotherm 51 GL to be used in individual development projects without additional thermal insulation,”says Dmitry Kim, Lead Product Development Manager at Wienerberger.
According to experts' calculations, the average cost of a new item is comparable to the price of aerated concrete structures. In addition, if we talk about complex investments in the project, then the ceramic blocks win. The light weight of the blocks allows you to reduce the load on the foundation to 30 tons and reduce the cost of its installation, creating a less massive structure. Also, ceramics has increased strength (M100) and does not need reinforcement and installation of a concrete monolithic belt, as required by foam and aerated concrete.
The increased strength of the product is the result of the development of a unique composition of several types of clay. At the same time, this decision enabled Wienerberger to offer products to the market that are significantly lighter than products from other manufacturers. So, with the dimensions of Porotherm 51 GL 510x250x219 mm (14.3 nf2), their weight is only 16 kg, which is up to 40% less than that of similar products. This ensures the manufacturability and convenience of the construction process, speeds up the process of building a building, and also reduces logistics costs.

High frost resistance (100 cycles) ensures the durability of the material. Blocks do not require special protection if there are seasonal breaks in construction.
In the Porotherm series, halves and solid blocks are presented. A wide range of products allows you to eliminate unnecessary operations on site - for example, sawing and fitting blocks. Thus, it is possible to carry out construction work in the shortest possible time without compromising their quality and appearance of the masonry.
Additional ease of installation is provided by a comprehensive construction system from Wienerberger, which includes all related products: warm mortar, light plaster, anchors, lintels, tools, etc. The use of accessories from the manufacturer also significantly improves the thermal performance of buildings. For example, the composition of the solution includes perlite, which has a thermal conductivity of only 0.19 W / m ∙ ° С (for comparison, the same indicator for cement is 0.93 W / m ∙ ° С), which avoids the appearance of "cold bridges" in place joints.
Porotherm 51 GL units have passed mandatory checks for compliance with all applicable standards. “We have been testing and certifying Wienerberger products for seven years and are familiar with their modern factories and responsible approach to production,” comments Nikolay Sapelin, General Director of VNIISTROM-NV LLC, an independent organization in the field of testing and certification of building materials. - I can confirm that according to the test results, the new product Porotherm 51 GL fully complies with the requirements of GOST 530-2012."
