The Logix system offers 7 thickness and types of foam panel to match your thermal demands, with Logix you can build to U values as low as 0.1w/m2
k ( or lower), or a 0.17w/m2k in a finished wall 300mm thick.
But thermal performance is not just about U values. Most buildings and walls in particular loose more heat than predicted due to inbuilt thermal short cuts. Short cuts which building with Logix avoids.
