Comprehensive support in the planning

Heytex provides radiation-related physical measurements for planning purposes

Weaving, coating, laminating: The expertise in these areas makes Heytex a world leader in the manufacture of technical textiles for tents, textile halls, shade sails and so on. Such sophisticated high-performance fabrics can only be created with the help of in-depth expertise and continuous development. Handling them requires utmost care and precision.


It is well known that sunlight is divided into UV, visual (light) and energetic (heat) radiation according to wavelength. While harmful UV radiation should always be completely excluded, the purpose of use in tents and textile halls determines whether light or heat should reach the interior or be kept away as far as possible.


Heytex cooperates with Fraunhofer Institute for Building Physics (Fraunhofer Institut für Bauphysik) in order to offer its customers comprehensive planning support. UV, light and heat radiation are measured according to DIN EN410 and ASTM G173 / E903 standards in terms of permeability, absorption and reflection. Together with the U-value, these values result in the so-called g-value (total energy from permeability and radiant heat of the absorbed radiation into the interior), which forms a component for calculations and simulations of the room climate in the tent.


In addition to the g-value, the Solar Reflectance Index (SRI) also plays a decisive role in planning. The SRI value takes into account the climatic impact of the building on its surroundings when certifying buildings according to LEED – especially in summery framework conditions.


Thus, Heytex not only offers the right material for every application (from blockout to standard materials in a wide variety of colors up to highly translucent goods), but also support the decision-making and planning process in all phases.


Faithful to the company’s mission statement: You have the challenge, we have the right material.
