Twista Grande Domestic Roof Vent Review
RVA does not install Twista Vents – This Article is for information purposes only
Twista Grande is the standard whirlybird offered by Twista. Although significantly large in size, this roof ventilator is geared at homeowners. Twista is known for manufacturing extra-large whirlybirds, so it is no surprise that this domestic ventilator has a 500mm throat size. Compared to 300mm whirlybirds more commonly available across Australia, Grande is more than double in size and delivers a more heavy-duty performance.
Twista Grande is constructed from exceptionally durable and sturdy materials. The ventilator has an all-metal construction and features twin steel bearing design. This design ensures that the bearings function perfectly over the years and require no maintenance or replacement on your part. It also makes sure that the ventilator operates in a very quiet and smooth fashion.
Grande uses wind energy to rotate which is why it should ideally be installed at a suitable rooftop position. Wind-driven operation translates into zero ongoing energy costs. In fact, Grande can reduce the load on your air-conditioning system by offering highly effective ventilation. In the long-term, this leads to smaller energy bills.
A slight downside to Grande is its extra-large size. This may be perfect for medium-sized homes but smaller homes may not require a 500mm whirlybird for ventilation. If you need to ventilate a smaller roof space or area, you may go with another brand like Ampelite or CSR Edmonds.
That being said, you can be sure that Grande offers genuine quality. The whirlybird has been rigorously tested to be completely water-proof, so you don’t have to worry about the rain leaking through the vent. Besides, the company offers an astonishing 25-year warranty on its Grande ventilator. This is an excellent return-on-investment for the money you may spend on purchasing and installing this whirlybird.
