What is Vestibule?
A vestibule is a small area between the outside and the main part of a building. It serves as a transition space before entering the main room or hallway.
Definition
Purpose
A vestibule is to create a separation between the outside environment and the interior of a building. This space helps to reduce the amount of outside air, dust, noise, and moisture that enters when doors are opened. In both commercial and residential buildings, vestibules help improve energy efficiency by helping to maintain indoor temperatures. Additionally, they often provide a more organized and welcoming entrance for visitors before they enter the main area.
Examples of Use
- Office buildings: Vestibule construction is done near entrances to help control indoor heating and cooling.
- Residential homes: A vestibule also provides a small transition area before entering the living space.
- Commercial spaces: Stores and hotels often use vestibules to improve comfort and reduce outside noise.
