Silver Insulation Underlay | 4 mm, 30 cm × 1 m

Precision sizing for targeted installations.

At 4 mm thickness and 30 cm width, the Silver underlay is tailored for heating film and mat installations where a narrower format or slightly thicker insulation makes more sense. High-quality laminated material reduces heat loss and provides a stable base beneath panels, keeping everything level and performing as it should.

The heat-reflective layer improves heating system efficiency, helping floors warm up faster and keeping energy bills lower over time. The roll format adapts easily to any room layout, and fitting it is quick and straightforward.

Equally effective in new builds or retrofit heating upgrades — solid construction for lasting performance, and practical dimensions that let you match the underlay to the job at hand.
