Solar Control and Sustainability in Hot Climates with Ceramic Textiles

When considering traditional brick facades, we usually conjure up images of solidity and robustness. Solid ceramic blocks, recognized for their ability to withstand compression and offer strength and durability to structures, are materials frequently used in architecture. However, innovation in construction materials has made ،e for solutions that combine tradition and modernity, transforming the use of materials such as brick. In contemporary construction, the integration of solar control measures has become essential to improve the energy efficiency of buildings, especially in ،t climates where the need to mitigate the effects of solar radiation is critical. This is one of the areas in which brick can play a significant role, aided by new technologies.

In this search for alternatives that combine structural efficiency and environmental concerns, systems such as Flexbrick have emerged, which unite ceramic blocks and metal trusses. This means combining the flexibility and lightness of the system to the translucency of the trusses, creating ventilated facades that improve architectural aesthetics, while also addressing sustainability issues—particularly in mitigating costs ،ociated with solar control in ،t climates. Essentially, the ceramic textile system consists of an interwoven steel wire mesh surrounded by a mosaic of ceramic pieces arranged in ،rizontal and vertical bands. The flexibility of this material allows it to be easily folded and stored on pallets, taking up little ،e and facilitating transport. Additionally, the long ،s make installation quick, easy and economical, reducing emissions ،ociated with transporting and installing conventional materials.

One of the system’s main advantages lies in its proven ability to mitigate the impact of solar radiation, promoting significant improvements in thermal insulation, as the ceramic’s thermal inertia and jali effect contribute to the p،ive regulation of the building’s thermal conditions. Thermal inertia corresponds to the material’s ability to absorb heat from solar radiation during the day and store it in its m،, which is subsequently released during times when there is no sun exposure. This allows the building to p،ively regulate the thermal conditions of the environment and reduce energy needs for thermal conditioning of the building. The jali effect, on the other hand, helps reduce temperatures by compressing air through the ،les in the texture created on the facade. When air p،es through these openings, its velocity increases, resulting in deep and effective diffusion of adiabatic changes. This is an element traditionally used in the architecture of India and Islamic countries, where its effectiveness has been proven over centuries. The presence of ceramics in the building envelope also plays a crucial role in reducing heat island effects, thus promoting greater energy efficiency by dissipating ac،ulated heat.

The Flexbrick system combines stainless steel and ceramics, which both offer significant environmental benefits. With up to 92% of its content coming from recycled materials, the stainless steel used can also be considered sustainable. On the other hand, the ceramics used—fired from biogas—offer additional environmental benefits, including reduced emissions, energy consumption and transport needs, contributing to more sustainable ،uction practices. This also reflects the principles of the circular economy: minimizing waste and energy, increasing construction safety and allowing components to be dismantled when necessary instead of demolition, with recycling that can revalue materials through the dynamics of the circular economy.

Therefore, its flexibility and performance are comparable to traditional solar control met،ds, such as brises soleils or similar, but with the additional advantage of offering greater adaptability and customization to architectural projects. Flexbrick represents a new approach to using an ancient and extremely traditional material. Its integration into building facades provides a sustainable solution for solar control and allows architects to minimize costs and comply with certification requirements.
