Air Tightness
Air Tightness
A Key Factor in Efficiency
Achieving airtightness is vital for retaining warm air indoors and keeping cold air outside. Eliminating drafts not only enhances living comfort but also boosts energy efficiency, resulting in lower heating costs. Airtightness additionally safeguards the building structure, preserving its appearance and extending its lifespan.

- Upper Limit for Air Permeability: 7 m³/(h·m²)
How to Achieve Airtightness
The key to airtightness lies in creating a consistent, air-resistant layer throughout the building. This includes areas where walls meet floors, around door and window openings, and behind plaster slabs on upper ceilings. C&W Insulations, as certified contractors of the SIGA Air & Wind tightness System, utilise a range of tapes, adhesives, and SIGA Majpell, a certified vapour control layer, ensuring a comprehensive and continuous airtightness solution.
