4heat’s catalogs, price lists, and technical documentation were developed into a consistent product information system. The materials cover a wide range of heating and cooling units, each defined by detailed technical parameters, configuration options, and performance data. The work centered on establishing clear hierarchy, modular grid logic, and typographic precision to improve readability across dense technical content. Specifications, data tables, and pricing structures were structured into a coherent framework to ensure consistency across all materials. The result is a robust system that supports technical clarity and brand coherence across both printed catalogs and digital documentation.
