Installing a louvre vent on a corrugated steel garden shed can be a bit challenging, but it's not impossible. While finding a vent specifically designed for corrugated walls may be difficult, you can still install a standard vent and take some measures to make it waterproof. Here's a step-by-step guide to help you:
Gather the necessary materials: You'll need a louvre vent, silicone sealant, screws or rivets (appropriate for metal), a drill, a screwdriver or rivet gun, a ladder, and safety equipment.
Choose the vent: Select a standard louvre vent that suits the size and airflow requirements for your shed. Even though the vent surround may not perfectly match the corrugated walls, it can still be installed effectively.
Determine the vent placement: Find the most suitable location on the shed wall to install the vent. It's advisable to position it higher up to prevent water ingress during heavy rain.
Measure and mark the vent position: Use a tape measure to ensure accurate placement. Mark the position on the corrugated wall with a pencil or marker.
Prepare the vent: Apply a layer of silicone sealant along the bottom edge of the vent surround. This will help create a watertight seal once installed.
Drill pilot holes: Use a drill with a metal drill bit to create pilot holes at the marked positions on the shed wall. These holes will guide the screws or rivets during installation.
Install the vent: Position the vent over the pilot holes and align it with the marks on the wall. Secure the vent in place by driving screws or rivets through the pilot holes and into the wall. Make sure they are tight but not over-tightened to avoid damaging the shed.
Seal the edges: Apply a generous amount of silicone sealant along the edges of the vent surround where it meets the corrugated wall. This will create a waterproof barrier and prevent water from entering through gaps.
Check for leaks: Allow the silicone sealant to cure as per the manufacturer's instructions. Once it's dry, spray water onto the vent and observe if any water leaks inside the shed. If you notice any leaks, apply additional sealant to the problematic areas.
Maintain the vent: Regularly inspect the vent to ensure it remains in good condition. Replace any damaged or deteriorated sealant promptly.
Remember, this guide provides general instructions, and it's important to consider the specific requirements of your shed and the instructions provided with the louvre vent you choose. If you're unsure about any steps, it's always recommended to consult a professional or reach out to the manufacturer for guidance.
