How to choose Agrob Buchtal tiles

Choosing the format and surface of facade tiles is an important decision in building design: it determines the scale of the composition, the rhythm of the facade, the installation methods, and the operational characteristics. In this article, we will discuss how to choose Agrob Buchtal tiles for various architectural tasks - from proportions and textures to technical limitations and tips for practical application.

Why format and surface are important for architecture

The impact of format on the perception of a building

The tile format determines the visual scale of the facade. Large formats make the facade more minimalistic and “calm,” creating a sense of monolithicity and modernity. Smaller modules allow for detailing, creating mosaic rhythms or ceramic graphic accents.

The role of surface (glazed vs. unglazed; texture)

The surface affects light reflection, color perception at different angles, and facade maintenance. Glossy and silky matt surfaces enhance color saturation and reflect light; rough or textured surfaces add plasticity and interesting shadow effects. Agrob Buchtal offers both smooth and embossed solutions, giving you freedom in your architectural design.

Agrob Buchtal range: available formats and surfaces

Wide range of formats

Agrob Buchtal offers a wide range of formats, from narrow modules to large-format panels. For example, in the KeraTwin line, formats can reach heights of up to 60 × 180 cm, and the length of the panels is often ordered individually in millimeters, which allows you to avoid unnecessary joints and precisely fit the elements to the facade dimensions. This is important when designing large smooth areas or when you want to minimize the number of vertical joints.

KerAion large-format panels and their features

For projects requiring minimal seams and a “glass-like” uniform surface, Agrob Buchtal offers thin large-format panels (KerAion) that are 8 mm thick and weigh approximately 18 kg/m², which facilitates transportation and installation while maintaining the strength of the material. These panels are fastened with clips and are designed for ventilated facades.

Surface options (Hytect and other technologies)

Agrob Buchtal has surface coating technologies that facilitate maintenance—for example, Hytect ensures self-cleaning of the surface under the influence of rain and sun, which is useful for urban environments with air pollution. In addition, glazed and unglazed series, matt and textured options are available, offering a wide choice for architectural expression.

How to choose a format for an architectural project - a practical algorithm

Step 1. Determine the scale and style of the building

  • Large-format panels (e.g., 60×120, 75×150 cm, or even larger) are suitable for minimalist modern facades, creating “clean” planes.
  • For historic or facades with rhythmic decomposition, smaller modules or rectangular thin strips are suitable, which will emphasize the articulation of the surface.

Step 2. Measure the dimensions of the window openings and elements

Plan the format so that the joints of the slabs coincide or logically correspond to window openings, balconies, etc. This reduces the number of cuts and provides neat joints.

Step 3. Consider technical installation limitations

Large format means more load on the subsystem and specific fastening requirements; thin large panels (8 mm) may look light, but require an appropriate subsystem and fastening with clips. Coordinate the choice of format with the contractor and the manufacturer of fastening systems.

Choosing a surface: aesthetics, care, and maintenance

Light reflection and color on different surfaces

Glossy surfaces enhance color and shine; matte surfaces add solidity and “architectural weight.” Textured surfaces create a play of light and shadow, which is useful for large facades where monotony should be avoided.

Care and resistance to contamination

If the facade is located in an urban or industrial environment, give preference to coatings with a self-cleaning effect (Hytect) or less porous glazed options - this will reduce maintenance costs.

Color adaptation to the environment

Choose a tile palette that suits the surroundings: natural shades for parks and coastal areas, cool technical tones for office and industrial areas, warm textures for residential areas. Agrob Buchtal has a wide range of colors and can fulfill special orders for precise shade matching.

Practical tips: how to combine format and surface in a real project

Tip 1 - Test real samples

Order sample panels or samples, view them in natural light on the facade (morning, noon, evening). Color and texture may vary under different lighting conditions.

Tip 2 - Minimize the number of different formats

For cost-effectiveness and logistics, use the minimum number of formats necessary: each new format means additional costs for cutting, fitting, and an increased risk of defects.

Tip 3 - Think of seams as a design element

Joints do not necessarily need to be concealed; they can become a rhythmic element of the facade. Choose the joint width according to the size of the slabs and the desired visual effect.

Short checklist

  1. Determine the architectural style and scale of the facade.
  2. Select the desired surface (glossy/matte/textured/Hytect).
  3. Choose a format so that the joints logically match the facade elements.
  4. Agree on technical restrictions with the contractor and manufacturer.
  5. Order samples and test them on site.


  • Check the compatibility of the format with the fastening subsystem.
  • Consider the logistics of transporting and storing large-format panels.

Mistakes when choosing and how to avoid them

Common mistakes

  • Choosing a large format without considering the installation subsystem → mounting problems.
  • Insufficient testing of samples in natural light → color differences on the facade.
  • Excessive use of different formats → increased costs and installation complexity.

How to avoid

  • Consultation with the Agrob Buchtal technical department or an official dealer.
  • Development of joints and transitions at the design stage.
  • Mandatory fitting of samples on site.

Conclusion - how to choose Agrob Buchtal tiles to match the architecture

Selecting the tile format and surface is a combined decision: aesthetics + technology + functionality. Agrob Buchtal offers flexible format options (including large-format KeraTwin and KerAion) and a variety of surfaces (including Hytect for easy care), providing ample scope for architectural implementation. Plan the format so that it emphasizes the architectural proportions, coordinate the selection with the subsystem and contractor, and be sure to test samples on site before placing a bulk order.
