Pro Clima airtightness and windtightness products are essential components in any low-energy or passive house build. They work in tandem with natural insulation to significantly improve thermal performance, reduce heat loss, and manage moisture within the building fabric. From walls to roofs and floors, the Pro Clima system delivers durable, breathable protection that enhances comfort and energy efficiency in both new builds and retrofits.
At the heart of the system are intelligent vapour control membranes such as Intello Plus and Dasatop, which adapt their vapour permeability depending on humidity levels. This helps prevent condensation and mould while allowing structures to dry out safely. These membranes are used on the warm side of insulation to provide airtightness and vapour control. For the cold side, Solitex Plus and Solitex Fronta WA windtight breather membranes protect insulation from windwashing and external moisture, while maintaining breathability. Pro Clima’s range of airtight tapes, sealants, and grommets. Tescon Vana, Contega Solido SL, Orcon F, Kaflex, and Roflex ensure long-term airtight seals around overlaps, junctions, and penetrations.
These components create a continuous airtight and windtight envelope around the building, supporting compliance with building regulations and helping to meet Passivhaus or EnerPHit standards. Pro Clima’s systems are robust, easy to install, and backed by extensive testing and building physics research, making them a trusted choice for sustainable, high-performance construction.
About Pro Clima Airtight & Windtight
Airtightness and windtightness are essential to achieving the full thermal performance of any insulation system. Pro Clima’s membranes, tapes, and accessories work together to form a robust, breathable building envelope that protects against heat loss, air leakage, and moisture build-up.
Internal membranes like Intello Plus and Dasatop ensure airtightness and manage vapour diffusion by adjusting to changes in humidity, creating a smart vapour control layer that minimises the risk of condensation and safely speeds up drying in constructions using wet materials (e.g. plaster, screeds etc). Externally, Solitex Plus and Solitex Fronta windtight membranes prevent wind-driven air movement through the insulation layer, helping to eliminate thermal bypass and maintain U-value performance.
These membranes are complemented by high-performance sealing products like Tescon Vana (for overlaps), Contega Solido SL (for junctions), and Orcon F (for uneven surfaces). For sealing cables and pipes, Pro Clima Kaflex and Roflex grommets ensure a long-lasting airtight seal. Together, these components deliver a high-performance, energy-efficient building envelope.
Pro Clima airtightness and windtightness systems work in harmony with natural insulation to improve energy efficiency, reduce condensation risk, and enhance comfort. Intelligent membranes like Intello Plus and Dasatop adapt to humidity, supporting safe drying and preventing mould. Windtight membranes like Solitex Plus shield insulation from windwashing while remaining vapour open. Pro Clima’s tapes, sealants, and grommets ensure durable seals around all overlaps and penetrations. These systems enable buildings to achieve low U-values and high airtightness standards, helping meet Passivhaus and building regulation targets. Together, they form a robust, breathable envelope for healthy, low-energy buildings.
