Semi-Exposed Walls - Aircrete Design Guide

Semi-Exposed Walls (Walls Adjacent to Unheated Spaces)

Walls adjacent to unheated spaces are now treated as exposed walls (but with an allowance for the space), and are therefore required to achieve a U-value of 0.35 W/m²K or less when complying with the Elemental Method or a maximum U-value of 0.70 W/m²K, using either of the whole house methods of compliance.
