Frame Conductivity

Conductivity determines how quickly heat energy flows from “where it’s hot to where it’s not”

Lower frame conductivity means better insulation

A low "U-value" indicates superior performance

AA Series products outperform many competing aluminium windows by shielding the inside of the product with a hardwood 'inline' reveal

TB Series products are thermally broken, featuring a polyamide insulator between inner & outer faces
