Double-layered walls

Definition

Double-layered walls refer to an energy-efficient building design technique where two layers of walls are constructed with an air gap between them. This air gap acts as insulation, reducing heat transfer and improving energy efficiency.

Analogy

Think of double-layered walls as wearing multiple layers of clothing during winter. Just like the extra layer traps warm air close to your body, double-layered walls trap air between them, preventing heat loss or gain from outside.
