For 4heat, I developed a series of print campaigns and feature layouts published in the professional magazine TOPIN. The goal was to translate complex heating and cooling technologies into communication that is direct, structured and relevant for installers, engineers and technical decision-makers. Each layout balances strong visual presence with disciplined hierarchy. Headlines lead, performance data follows, and key benefits are framed within a consistent visual system built on gradients, technical line graphics and clear typography. The result is precise, confident communication tailored for a technical audience.
