Louvre Window Vents

About Our Louvre Window Vents 🍃

A Louvre Window Vent is one of the most effective ways to improve air circulation and control the temperature within your growing space. Unlike standard vents which let hot air escape, louvre vents are designed to be installed lower down in the greenhouse frame. This creates a "chimney effect," drawing cool, fresh air in at the bottom while pushing stale, hot air out through the Greenhouse Roof Vents. This constant airflow is vital for preventing plant scorch and reducing humidity-related diseases.

Our collection features high-quality Elite Louvre Vents and Vitavia Louvre Vents designed to integrate seamlessly with your specific greenhouse model. Whether you need Toughened Glass Blades for a classic look or Polycarbonate Blades for added insulation, we have the right solution. All our vents come with a 10 Year Warranty on the frame and Free UK Delivery, ensuring you get a durable product that protects your plants for years to come.

Choosing Your Louvre Window Vent 🛠️

Selecting the right vent depends largely on your greenhouse brand and your preferred level of automation. Most standard 6ft wide greenhouses benefit from at least one louvre, while larger 8ft or 10ft models may require two for optimal cross-ventilation. We offer vents in silver, green, and black to perfectly match your frame.

Prices start from approximately £35 for manual kits, making this an affordable upgrade. For a complete climate control setup, we recommend pairing your vents with Greenhouse Staging to organise your plants in the airflow path, or Greenhouse Heaters for winter protection.

Frequently Asked Questions about Louvre Window Vents 🤔

• What is the benefit of a louvre window vent?

  A louvre window vent introduces cool air at a low level, creating a cross-breeze that pushes hot air out through the roof. This "chimney effect" significantly reduces internal temperatures and prevents stagnant air pockets that cause fungal diseases.

• Can I add a louvre vent to an existing greenhouse?

  Yes, most aluminium greenhouses are designed to accept retrofit louvres. You typically remove a pane of glass and replace it with the louvre kit, which slots between the glazing bars. Always check our Greenhouse Spares section or contact us to ensure compatibility with your specific brand.

• Should I choose glass or polycarbonate blades?

  Choose Toughened Glass Blades if you want a traditional aesthetic that matches your greenhouse glazing and offers weight for stability. Select Polycarbonate Blades if you prioritise safety and thermal insulation, as they retain heat better during cooler nights.

• How do automatic louvre openers work?

  Autovents and Openers use a wax-filled cylinder that expands as the greenhouse temperature rises, pushing a piston that opens the louvre blades. They require no electricity or batteries and automatically close as the temperature drops, providing complete peace of mind.

• Which louvre vent fits my greenhouse?

  Compatibility is key. We clearly list compatible accessories on each product page. For example, Elite models use specific dimensions that differ slightly from other brands. We ensure you only see accessories that actually fit the greenhouse you are buying—we have been selling greenhouses for over 15 years and know exactly what works!
