Frame Conductivity

Conductivity deems how fast heat flows from “where it’s hot to where it’s not”

Lower conductivity = better insulation

A low "U-value" = better insulation, thus superior thermal performance

AA Series products shield part of the aluminium frame with a hardwood 'inline' reveal, minimising heat transfer

TB Series products are thermally broken, featuring a polyamide insulator which isolates thermally the inner & outer faces


What is a "U"-value?
