Louvres are currently a fundamental part of most buildings and HVAC systems. They add to your property’s aesthetic appeal while reducing your energy costs. They are also easy to install and come in a wide range of materials and colours to suit any project.
There are two categories of louvres, external and internal. Both types of louvres are used in air systems, doors and windows. Here are the three main groups of external louvres.

Screening Louvres

Screening louvres provide an inadequate level of protection from weather elements. They are ideal in places where rain penetration is not an issue. They are also suitable in areas sheltered from extreme weather conditions. They are often found on top of buildings where they cover HVAC systems and other unsightly equipment.

Standard Ventilation Louvres

These louvres offer maximum airflow in addition to some protection against rain. They are ideal for projects whose primary consideration is cost and those that need a high free area. They are also suitable in places where intermittent water penetration will not cause substantial problems. When purchasing standard ventilation louvres, specifying your desired free area and blade spacing is essential.

Weather or Performance Louvres

The primary aim of weather louvres is to provide protection from rain and allow the flow of air. There are two basic specifications you should consider when buying weather louvres: airflow and water penetration. Airflow is based on your louvre’s required volume flow rate and the size of its face. Water penetration is determined by your weather conditions and the acceptable degree of water infiltration.
After selecting the correct louvre for your project, it is essential to get a good supplier. Ensure the supplier appreciates what precisely your project involves. This will help them offer the appropriate technical data that suits your application. Having a committed installation team guarantees your louvres for your windows or walls are fixed according to the manufacturer’s specifications.
