Xella has its own unique solution for building residential buildings

Xella has construction materials for all large and small projects in the field of residential construction. In particular, large-format blocks Ytong and Silka are suitable for the construction of apartment buildings. The services also include complete technical support and the concept of digital planning Xella blue.sprint.

Construction of apartment buildings up to four above-ground floors

For this type of construction, it is already advantageous to use larger formats, which allow the building to grow faster. Large-format elements and blocks also save time during design, and a multidisciplinary 3D model in BIM technology can be well and efficiently prepared with them. Perimeter walls in similar projects are constructed from large-format Ytong Jumbo elements. Designers positively evaluate their excellent thermal-technical properties, while investors appreciate the fact that these large-format blocks for external perimeter walls can be laid in one step over seven times larger area. Ytong Jumbo elements also reduce personnel demands – only two workers are sufficient to work with them, and due to this technology, the work is physically less strenuous for them. An unbeatable solution for thin load-bearing perimeter and internal walls are large-format Silka Tempo blocks. They can also be used to build stiffening, filling, and fire walls with high load-bearing capacity and high acoustic insulation. The system of these large-format aerated concrete blocks, combined with Ytong Jumbo products, offers the highest construction efficiency. The wide range of products allows for wall construction without lengthy cutting or splitting on-site.

Silka Tempo blocks are ideal for taller apartment buildings

They have a similar composition to Ytong but have a load-bearing capacity resembling concrete. Their use shortens the masonry time by up to sixty percent and reduces the physical demands on workers. The most economical solution for internal non-load-bearing and partition walls is offered by Ytong partition panels. These panels are constructively reinforced and are made to measure according to the floor height, with a maximum height of 2.9 meters. They are ideal for large areas with minimal subdivisions and a requirement for fast construction, and their use can save up to half of the workforce. A significant increase in prefabrication is represented by the use of Ytong SWE load-bearing wall panels.

Complete technical support is part of Xella's services

For all large-format products, Xella provides complete technical support. This includes static consultations and assessment of savings and benefits due to large-scale materials. For walls made of aerated concrete blocks, Xella prepares and supplies laying plans, trains personnel directly on-site

and provides cranes and assembly tools. Last but not least, it is important to mention that Xella, as a supplier, is also optimal from an ecological perspective – the company has long focused on conserving natural resources, reducing energy use and emissions, thus contributing to obtaining certifications for buildings in LEED/BREAM systems.

The concept of digital planning Xella blue.sprint

enables the realization of optimized and efficient building designs, and its use brings comprehensive project solutions, especially with an emphasis on speed, quality, and construction efficiency. The concept includes assisting investors and developers in optimizing material selection, consultations for designers, preparation of a digital product database, and seamless order and supply chains. The advantage of all these services is that they are interconnected throughout the entire project cycle: from the planning phase, through production, delivery, and realization to sustainability and operation.

Services also include statics optimization, such as feasibility assessments, composition assessments and designs from a thermal-technical and acoustic perspective, or proposals for procedures and feasibility assessments using large-format elements. The design is presented to the client in the form of a BIM model utilizing online presentation. Moreover, information exchange occurs in real time, allowing participants to always have immediate access to current data without having to wait for it to be shared.
