Whether you're dealing with a stuffy upstairs room, a hot roof space in summer, or moisture build-up causing damage, a properly sized whirlybird installation can significantly improve airflow and comfort.

Frequently Asked Questions
Do you supply and install whirlybirds in Cape Town?
Yes. IR Installers supplies and installs whirlybird roof ventilators throughout Cape Town and surrounding areas. We install whirlybirds on residential, commercial and industrial roofs to help remove trapped heat and improve natural roof ventilation. Contact us for advice on the correct size and number of whirlybirds for your property.
Why is ventilation important?
Energy Efficiency – By allowing trapped hot air to escape from the roof space, whirlybird ventilation can help reduce heat build-up during warmer weather. This may reduce some of the cooling demand on air-conditioned buildings, while the whirlybird itself operates without electricity.
Increased Comfort - With proper roof ventilation, you can enjoy a more comfortable living space. By removing hot air and moisture from your attic, ventilation helps regulate the temperature and humidity levels in your home, creating a more pleasant environment.
Extended Roof Lifespan - Roofing materials are exposed to extreme temperature fluctuations and moisture levels. Without proper ventilation, these conditions can cause premature aging, leading to more frequent roof repairs or replacements. Ventilation helps alleviate these issues, extending the lifespan of your roof.
Moisture Control - Excess moisture in the attic can lead to the growth of mold, mildew, and rot. This not only poses health risks but also compromises the structural integrity of your home. Proper ventilation helps prevent moisture buildup, protecting your home from these issues.

How many whirlybirds do I need for my roof?
The number of whirlybirds required depends on the size and design of your roof, the amount of trapped heat and the ventilation already available. IR Installers can assess your property and recommend the correct number and positioning of whirlybird roof ventilators for effective airflow.
Will a whirlybird make my house cooler?
A whirlybird helps remove trapped hot air from the roof space, which can reduce heat build-up above the rooms below. The result depends on the size and design of the roof, the number and positioning of the ventilators, and whether sufficient replacement air can enter the roof space. In some installations, ceiling grilles can also help improve airflow by allowing warm air from inside the building to move into the roof space where it can be extracted.
How much does whirlybird installation cost in Cape Town?
The cost of whirlybird installation depends on the type and number of roof ventilators required, the roof type, access and the complexity of the installation. IR Installers can assess your requirements and provide a quotation for the supply and installation of the correct roof ventilation solution.
