The Finishing Touch: A Pro's Guide to Louvres & Grilles

You've installed a powerful exhaust fan and run the ducting perfectly, but the job isn't complete until you've installed a proper termination point. A simple hole in the wall or eave looks unprofessional, lets in pests, and doesn't control airflow. A high-quality louvre or grille is the essential finishing touch for any ventilation project.

At SCHNAP, our comprehensive range of Louvres and Grilles provides the durable, efficient, and stylish solutions that tradies and HVAC pros need to complete any installation to the highest standard.

The Right Vent for the Job

We stock a huge variety of vents to suit every application, inside and out.

  • Internal & External Grilles: The classic choice for covering the duct penetration in a ceiling or wall for your bathroom, kitchen, or laundry exhaust fan. Our grilles are available in a wide range of standard duct sizes and popular finishes, including white, black, and chrome, to match any decor.
  • Eave and Wall-Mounted Louvres: An essential component for effective roof space ventilation to combat the summer heat. Our eave louvres are also the perfect external termination point for ducting runs, with angled blades designed to let air out while keeping rain and pests from getting in.

Smart Designs for Better Airflow Control

Choose the right design for the level of control you need.

  • Fixed Blade vs. Gravity Designs: A fixed blade grille is always open. For exhaust fan terminations, a gravity louvre is the smart choice. Its lightweight flaps are pushed open by the airflow from the fan and automatically close when the fan is off, preventing backdrafts, insects, and cold air from entering the room.
  • Adjustable Vents: For ducted HVAC systems or specific ventilation setups, our adjustable vents allow you to easily control and direct the amount of airflow into or out of a space.

Built for Aussie Conditions

Every product in our Louvres and Grilles range is crafted from durable, high-impact materials designed to withstand the harsh Australian climate. We stock UV-stable plastics that won't go brittle in the sun and corrosion-resistant metals for long-term performance.
