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

Introduction: The purpose of louvres.

Louvres 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 louvres is to direct airflow and protect the interior of a building from the sun and weather. Louvres also help to improve the appearance of a building by adding texture and colour.

Louvre Types:

This document classifies louvres into eight categories: fixed, adjustable, operable, ridge, gable, storm, sunshade, and privacy. (brief descriptions below)

Fixed Louvers:
  • Fixed louvres serve as a stationary ventilation solution in areas that demand constant airflow but don’t require adjustment.
  • These designs are simple and commonly used to decorate buildings.
Adjustable Louvers:
  • Unlike fixed ones, adjustable louvres can be opened or closed to control airflow and ventilation.
  • Movable slats or blad These designs feature movable slats or blades that you can angle to control airflow. This adjustability gives you more flexibility in managing your indoor climate.
Operable Louvers:
  • Operable louvres are similar to adjustable louvres but are typically motorized for automated control.
  • Commercial buildings utilize louvres to allow occupants remote or building management system control over ventilation settings.
Ridge Vent Louvers:
  • Install ridge vents 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 types are installed at the gable ends of roofs to provide ventilation in attic spaces.
  • This design allows hot air to escape while preventing moisture buildup, helping to extend the lifespan of roofing materials.
Storm Louvers:
  • Storm louvres defend against extreme weather conditions like hurricanes and high winds.
  • Reinforced construction allows them to withstand intense pressure and impact, making them ideal for buildings in coastal or hurricane-prone areas.
Acoustic Louvers:
  • Acoustic louvres are specifically designed to reduce noise transmission while still allAcoustic louvres specifically target noise reduction while maintaining airflow.
  • HVAC systems use them commonly to mitigate noise pollution from mechanical equipment and outdoor sources.
Privacy Louvers:
  • Privacy louvres obscure views from the outside while still allowing light and airflow to pass through.
  • Residential and commercial settings utilize these devices frequently to achieve privacy while maintaining natural ventilation.
Sunshade Louvers:
  • Sunshade louvres block direct sunlight and reduce solar heat gain, thereby improving energy efficiency and occupant comfort.
  • Builders commonly install them on building exteriors, windows, and curtain walls to mitigate glare and reduce cooling loads.


They 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. It plays a crucial role in creating comfortable and visually appealing spaces.
