Louvers are a common feature in many homes and commercial buildings. They help in ventilation and shading. If you need new louvers or have old louvers that need repair, contact us today.

Introduction: The purpose of louvers.

Louvers are a common architectural feature found on the exterior of buildings. They are used to control air circulation and light infiltration into a building. The purpose of louvers is to direct airflow and protect the interior of a building from the sun and weather. Louvers also help to improve the appearance of a building by adding texture and colour.

Louvre Types:

Louvers are broadly classified into fixed,adjustable,operable,ridge,glabe,storm,sunshade,privacy Louvers which are briefed below.

Fixed Louvers:
  • Fixed louvers are stationary and cannot be adjusted. They are typically installed in areas where constant ventilation is required and where airflow regulation is not a priority.
  • These louvers are simple in design and are often used for architectural embellishment, providing a decorative element to building facades.
Adjustable Louvers:
  • Unlike fixed louvers, adjustable louvers can be opened or closed to control airflow and ventilation.
  • They feature movable slats or blades that can be angled to allow more or less airflow, providing greater flexibility in managing indoor climate conditions.
Operable Louvers:
  • Operable louvers are similar to adjustable louvers but are typically motorized for automated control.
  • These louvers are commonly used in commercial buildings, where occupants can adjust ventilation settings remotely or through building management systems.
Ridge Vent Louvers:
  • Ridge vent louvers are installed along the peak of a roof to provide passive ventilation.
  • They allow hot air to escape from the attic space, reducing heat buildup and improving overall energy efficiency.
Gable Louvers:
  • Gable louvers are installed at the gable ends of roofs to provide ventilation in attic spaces.
  • They are designed to allow hot air to escape while preventing moisture buildup, helping to extend the lifespan of roofing materials.
Storm Louvers:
  • Storm louvers are designed to protect against extreme weather conditions, such as hurricanes and high winds.
  • They feature reinforced construction and are engineered to withstand intense pressure and impact, making them ideal for buildings in coastal or hurricane-prone areas.
Acoustic Louvers:
  • Acoustic louvers are specifically designed to reduce noise transmission while still allowing for airflow.
  • They are commonly used in HVAC systems to mitigate noise pollution from mechanical equipment and outdoor sources.
Privacy Louvers:
  • Privacy louvers are designed to obscure views from the outside while still allowing light and airflow to pass through.
  • They are often used in residential and commercial settings to provide privacy without sacrificing natural ventilation.
Sunshade Louvers:
  • Sunshade louvers are designed to block direct sunlight and reduce solar heat gain, helping to improve energy efficiency and occupant comfort.
  • They are commonly installed on building exteriors, windows, and curtain walls to mitigate glare and reduce cooling loads.


louvers are much more than just architectural embellishments – they are essential components that enhance both the functionality and aesthetics of buildings. From promoting ventilation and privacy to offering weather protection and security, louvers play a crucial role in creating comfortable and visually appealing spaces.
