Intelligent Seals for Airtight Internal & Weathertight External Joints

As building regulations change, new solutions and practices are required.
The problem of unintentional air leakage from buildings has grown in recognition with the amendments to Part L in 2006 and 2010 requiring energy reduction targets to be addressed and the incorporation of mandatory air leakage testing.

The innovative "i3" system encompasses the concept of sealing out weather whilst sealing in comfort and energy savings. By selecting the appropriate products, a simple, cost effective installation will benefit the building owner / occupier for years to come and the long-term savings can be enjoyed by many.
