Double-shell masonry consists of two layers of masonry walls with an air space in between, providing better insulation and protection against moisture compared to single-shell masonry, which has only one layer of masonry. Double-shell masonry is more durable and offers improved thermal performance due to the air space acting as a barrier against heat transfer. Single-shell masonry, on the other hand, is simpler in construction and may be more cost-effective but lacks the same level of insulation and protection as double-shell masonry. **
