When choosing a steel door for your building, you may come across the term louver door. But what exactly does it mean, and why would you need one?
Louver doors are designed to provide both security and airflow, making them a specialist solution for certain environments. At Security Direct, we supply steel louver doors built for commercial, industrial, and public sector applications where both ventilation and strength are essential.
In this article, we’ll explain what a louver door is, its key benefits, and the situations where it’s most commonly used.
A louver door is a steel door fitted with one or more louvered panels (ventilation grilles). These panels consist of horizontal slats set at an angle, allowing air to pass through while restricting visibility and maintaining door strength.
Unlike solid steel doors, which are completely sealed, louver doors are specially engineered for ventilation without compromising security.
Louver doors are typically chosen where ventilation and security must work together. Common applications include:
Machinery such as boilers, compressors, and generators require constant airflow to prevent overheating. Steel louver doors provide the ventilation needed while securing expensive equipment.
Heat-sensitive electrical equipment and servers need cooling. Fire Rated Louver doors allow airflow to manage temperature while keeping access restricted.
Ventilation is crucial for hygiene and odour control in waste storage areas. A steel louver door helps reduce smells while keeping the area secure.
Steel louver doors are used in car parks and loading areas where natural airflow prevents the build-up of fumes.
Wherever air circulation is required but fire safety, security, and durability are non-negotiable, PAS24 louver doors are the ideal solution.

Steel louver doors are far more secure than timber or aluminium alternatives, offering high resistance to vandalism and forced entry.
Anywhere requiring complete fire separation or acoustic insulation, unless a specialist fire-rated louver door is installed.
Yes. The size, position, and number of louver panels can be tailored to your airflow needs.
