Stonetec may have been postponed, but the STEIN editorial team has been asking around and presenting you with lots of news from the fields of materials, construction chemicals, tools & more and art foundries in the 06/2020 print issue since the end of May. This news is now also published online – today the second part of the construction chemicals section

Thanks to new production methods and formats, ceramics are in greater demand both indoors and outdoors. The HMK. R157 intensive tile cleaner for cleaning and stain removal on tiles, porcelain stoneware, terracotta, brick, clay and clinker tiles. In addition to general soiling, this mildly alkaline cleaning concentrate specifically removes building dirt, oil and grease films, residues of wax-based or self-glossing care products and much more in indoor and outdoor areas. The demand for protective products without classic solvents is increasing, and now the HMK. S232 stain protection – water-soluble reinforced by HMK. S747 Fleckstop-Aqua. HMK.S747 Fleckstop-Aqua reduces the penetration of water, dirt, oil and grease and is ideal for protecting matt polished, sandblasted and rough surfaces of natural and artificial stone, and can also be used on unglazed tiles and brick products. HMK.S747 Fleckstop-Aqua is mildly acidic and not suitable for polished or shiny acid-sensitive surfaces made of marble or limestone. Due to the current situation, the next 100 cases will also be equipped with two mouth-nose protection masks.

PCI

PCI is completing the rapid screed range in its Novoment product family: the new Novoment Light rapid screed mortar has been designed on the basis of lightweight fillers and weighs around 50 percent less than conventional screeds. For screed layers as well as building renovators and tilers, this means problem-free screed work even where the weight per unit area plays a key role, e.g. on wooden beam ceilings and wooden floorboards as well as structurally critical substrates indoors and outdoors and in damp rooms. Renovations of old buildings and subsequent work can be planned and implemented more easily with this addition to the range of specialist quick-setting mortars. After mixing with water, the mortar is easy to apply and compact. Additional smoothing of the surface is hardly necessary after stripping and rubbing. A load-bearing, fully bonded screed layer is applied in just one work step. A great relief for construction sites that are difficult to access: Workers do not have to transport additional sand for mixing, easy, effort-saving handling in confined areas is easy on the health. PCI Novoment Light can be applied in around one hour and still dries quickly. The screed can be walked on after around six hours and tiles can be laid after just one day. The new ready-mixed mortar is low-shrinkage and low-curvature, virtually eliminating the risk of cracking in the edge areas. It is also suitable for use under underfloor heating systems, basement floors and in shower areas. Available in 15 kg bags with the same area performance as a conventional screed mortar, the 30 kg bag is also very low-emission in accordance with GEV-EMICODE EC1 PLUS. “We have developed a ready-mixed mortar that offers real added value for tradespeople and retailers. The development of such new products is based above all on our practical experience and the continuous exchange with processors and specialist dealers,” says Dr. Tobias Gutberlet, Product Manager Building Technology at PCI Augsburg.

Rising high above the Thuringian countryside, Wartburg Castle is one of the most representative cultural monuments in Central Europe. Since its inscription on the UNESCO World Heritage List, it has been one of the most outstanding testimonies to European history. Architecture, political events and literary tradition intertwine here to create a multi-layered cultural narrative.

The history of Wartburg Castle begins in the 11th century, when it was founded as the residence of the Ludovingian landgraves and from then on shaped the political power in the region. Even in the High Middle Ages, the palace, enthroned on a steep limestone cliff, was considered a masterpiece of late Romanesque architecture, whose design and ornamentation make it one of the most important secular buildings north of the Alps. This architectural heritage is evidence of the feudal character of Central Europe and forms one of the foundations for the later recognition as a World Heritage Site.
Wartburg Castle’s role as a center of courtly culture and memory grows through literary traditions such as the so-called Singers’ War, which was passed down in Middle High German poetry. At the same time, historical figures such as St. Elisabeth of Thuringia, whose life and work are closely linked to the castle, are becoming firmly established in the culture of remembrance. Even if some legends were mythically exaggerated, they still reflect the early symbolic value of the place in the cultural imagination.

The architectural appearance of Wartburg Castle is the result of a long development that underwent a profound transformation, particularly in the 19th century. After centuries of changing use and partial decay, the emerging Romantic period initiated a comprehensive restoration that was based less on a historically accurate reconstruction than on an idealized image of the Middle Ages. Under this premise, the Elisabeth Bower and richly decorated interiors were created, which today form an integral part of the complex.
From an art historical perspective, this combination of original 12th century parts and historicist additions is ambivalent: on the one hand, the preserved Romanesque building elements document the civil architecture of its time; on the other hand, the 19th century additions reflect the monument preservation and historical myths of the time. It was precisely this mixture of archaeological and symbolic authenticity that was taken into account in the UNESCO nomination, with the term “authenticity” not only referring to material originality, but also including the ideas and meanings anchored in the collective consciousness.

Wartburg Castle is more than just a stone relic – it is a place of profound cultural connections. Martin Luther’s stay here during his exile from 1521 to 1522, when he wrote the German translation of the New Testament from Greek in the so-called “Junker Jörg” room, was particularly influential. This achievement in the history of language had far-reaching consequences for theology, education and the German literary language as a whole and had a lasting impact on the cultural significance of the castle.
In the 19th and early 20th centuries, Wartburg Castle also became a symbol of national identity and political integration. Events such as the Wartburg celebrations of the German student movement became part of the collective memory, as did literary and musical adaptations in works by Richard Wagner, which romanticized the image of the medieval castle courtyard. Wartburg Castle also remains a living point of reference in cultural memory as an inspirational place for artistic debate.
In 1999, the site was inscribed on the UNESCO World Heritage List on the basis of two criteria: Firstly, as an “outstanding monument of the era of feudalism in Central Europe” (criterion (iii)) and secondly, as a site “rich in cultural references”, particularly emphasizing its connection to the history of the Reformation and the German unification movement (criterion (vi)). These criteria reflect the exceptional universal value that Wartburg Castle has beyond the borders of Thuringia. The castle not only documents the architecture and living environment of high medieval feudalism, but also exemplifies the profound influence of historical events and cultural upheavals on European civilization. The UNESCO designation therefore not only recognizes the material substance of the complex, but above all its role as a place of remembrance that inspires generations of visitors to reflect and research. The integrative perception of architecture, history and cultural impact makes Wartburg Castle a unique medium for communicating the past and present.
At a time when cultural heritage is increasingly being discussed in a global context, Wartburg Castle highlights the importance of historical sites as mediators of identity, memory and transnational understanding. Its place on the World Heritage List helps to secure this significance in the long term and make it tangible for future generations.

“Security” in architecture means more than just barriers and alarm systems – there is much more to it than that. This issue sheds light on how buildings can provide protection – be it against the forces of nature, theft or social conflict. Your planners do not see security as a restriction, but as a design potential. In order to avoid repellent gestures, they often find security-relevant solutions in the building form. […]

“Security” in architecture means more than just barriers and alarm systems – there is much more to it than that. This issue sheds light on how buildings can provide protection – be it against the forces of nature, theft or social conflict. Your planners do not see security as a restriction, but as a design potential. To avoid repellent gestures, they often find security-related solutions in the building design.

Security – a word that is supposed to reassure and yet often has the opposite effect. We all long for it, but we also know that there is no such thing as absolute security. A building can protect against rain and cold, a city can be well planned – but can architecture really guarantee that we feel safe? Or does it only create an illusion? And in the end, isn’t the feeling of safety just as important as the safety itself?

The last year alone has shown us once again how fragile our built and lived environment is. Collapsing bridges, poorly maintained high-rise buildings and natural disasters that destroy entire neighborhoods. At the same time, fear of attacks in public spaces is growing, and in many cities measures are being taken to turn urban squares and buildings into high-security zones. But do we really need to turn our built reality into bastions of concrete and cameras in order to feel safe? Or is there a more intelligent answer to the question of protection?

Architecture cannot guarantee absolute security, but it can create trust. It can shape spaces that convey a sense of security without restricting freedom. Architecture has the unique potential to master precisely this balancing act. From fire and earthquake-proof school buildings to carefully considered designs for public spaces: Security architecture must not rely solely on control and barriers, but must enable trust and freedom. A clever choice of materials, for example, can preserve a feeling of openness without sacrificing protection. Ultimately, it must not be about sealing things off, but about proactive design.

Security must not become an aesthetic of mistrust. Walls, bars, barriers and confined spaces may minimize risks, but they also separate us from each other. All too often, they stifle life. The most popular place, both inside and out, is often where people meet, where light and transparency dominate, where architecture acts as a social bond and thus serves a greater purpose.

This issue is an invitation to rethink security. We show projects that prove that protection does not have to mean control, but trust. That architecture not only erects walls, but also builds bridges – between security and freedom, between control and openness. Because true security is not created by fear, but by clever (re)planning, by courageous design and by a society that does not close itself off, but proactively takes the helm. Enjoy reading!
