Semi-Exposed Walls - Aircrete Design Guide

Celcon manufactures a wide range of quality aircrete products, available in a variety of grades and dimensions, and all conforming to BS 6073. This is the excellence of Celcon aircrete.

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.

Further guidance has been provided with regard to shelter factors for these 'semi-exposed' situations.
