We provide on-site installation of airtightness systems and membranes, along with practical consulting to support projects targeting Passivhaus or high-performance outcomes.

Our work includes the installation of external and internal membranes, taping and sealing of junctions, and resolving complex airtightness details on site. We also provide site reviews, coordination with trades, and guidance on sequencing to ensure the airtight layer is continuous and buildable in practice. Where required, we support the project through blower door testing stages, helping identify and resolve leaks to meet performance targets.
