A glass vestibule is a modern, transparent entryway enclosure that serves as a transitional space between the outdoors and the interior of a building. Typically constructed with tempered glass walls and doors, it provides an elegant and open feel while offering protection from the elements. A glass vestibule helps improve energy efficiency by minimizing air exchange, maintaining indoor temperatures, and reducing heating and cooling costs. It also enhances security and adds a stylish architectural feature to any property.
