Attic staircases

Attic staircases are an often-neglected part of a building's thermal envelope. A certified solution makes it easy and safe to implement a thermal bridge-optimised design. The Passive House Institute provides the thermal characteristics of attic staircases to assist in the balancing and recording of thermal bridges.
