The Foundry Collection introduces nine new colours and finishes to Hilltop’s iconic KOLOM radiator. Collaborate and The Hype Factory brought the project to life in Lisrace Forge at the Ulster Folk Museum, using the authentic setting of a working blacksmith’s workshop to capture the warmth, texture, and craftsmanship behind the collection. From the glow of the fire to the shower of sparks, every detail reinforces Hilltop’s ethos: Heighten your comfort. Transform your space. Warmth meets elegance.
