Pro Clima Underfloor System

The Pro Clima Underfloor System offers a high‑performance solution for achieving airtight, vapour‑controlled and energy‑efficient floors in both new build and retrofit projects. Designed to integrate seamlessly with modern insulation systems, Pro Clima underfloor products help prevent heat loss, moisture damage and uncontrolled air leakage at floor junctions.

This collection includes airtight membranes, intelligent vapour control layers, tapes, and sealing accessories engineered specifically for underfloor applications. When installed correctly, the system supports improved thermal performance, reduced condensation risk and long‑term building durability, making it ideal for low‑energy, Passivhaus and sustainable construction projects.

Pro Clima’s advanced materials adapt intelligently to changing moisture conditions, allowing floors to dry safely while maintaining airtight integrity. This helps protect structural elements, insulation layers and indoor air quality throughout the building’s lifespan.

Suitable for timber floors and suspended floors, the Pro Clima Underfloor System is trusted by contractors, architects and self‑builders who demand reliable performance backed by rigorous testing.

Explore the full range of Pro Clima underfloor membranes and airtightness accessories to create compliant, energy‑efficient floor constructions that meet UK building regulations and best‑practice standards.
