With Twista Roof Ventilators installed hot air is literally sucked up and out of the roof space before it even has a chance to accumulate. No longer is your roof a heat-sink, it is now a heat-extractor!

Positive points

Even the slightest breeze has the Twista Ventilator spinning quickly. The faster it spins the more effectively it stucks the water vapour out of your roof and into the atmosphere outside.

Positive points

Fresh air is pulled in under the eaves of the house helping to cool down the roof space.

Positive points

Twista Ventilators, coupled with ceiling vents, suck-up and extract rising hot air whilst simultaneously pulling cool, fresh-air throughout the house. All of this occur naturally without any energy consuption!

Positive points

Ovens, cook-tops and other cooking appliances add huge amounts of unwanted heat your home. Twista Roof Ventilators quickly remove this heat and steam from the kitchen making cooking-time a lot more pleasant.

Positive points

All that hot steam from your shower is ejected out of your home ensuring that you won't be all hot and sweaty again after you have dried off.

Negative points

How do you like your eggs? You can cook an egg on a tin roof in summer. No joke!

Negative points

Unventilated roofs reach extremely high temperatures in summer. And this leaches a huge amount of heat through your ceiling and into your rooms.

Negative points

Insulation works well, but because it is heat-sink, once it is fully saturated with heat (wich happens very quickly in summer) it begins releasing heat through your ceiling and into your home. Insulation alone is not enough.

Negative points

In summer even your walls can add to the heat inside. Here is a fun question to ponder, what do many homes and pizzas ovens in common? That's right...bricks! We need something to combat this!

Negative points

Ceiling fans can cool sweat on your skin but they are pretty ineffective at cooling down your home. Think about it! Hot air rises but a ceiling fan simply pushes it back again. What you really need is ventilation!

Negative points

We all need to see the nice view outside, but windows are a large source of heat in summer. If your house is not well ventilated huge amounts of heat are trapped inside.

Negative points

A poorly ventilated kitchen it becomes like an unbearable sauna in the hot summer months.

Negative points

Hot steam from places like the bathroom and laundry make your home more hot and humid in summer. This steam can reach every room of the house making life in summer sticky and uncomfortable.

Positive points

Twista Roof Ventilators keep fresh-air flowing through your roof space. This keeps your insulation bats free of mould. Your structural timber will also remain strong and dry preventing wood-rot.

Positive points

In the wet winter it's important to remove excess moisture from your house before it has a chance to settle. Twista ventillators together with ceiling exhaust fans is great combination to extract water vapour.

Positive points

Cool air in the roof doesn't hurt! Have you noticed how clothes hung outside on a windy day will dry rapidly even if the wind is cold? Take advantage of this phenomenon by keeping air moving through your roof cavity!

Positive points

Fresh airflow is important in winter too. You want to stay cosy and warm of course, but a small amount of freshly supplied air is still needed to keep the indoor environment fresh and healthy.

Positive points

With a supply of fresh moving air the walls and carpets stay dry making it impossible for mould to take hold, even in the wettest of winters. Walls and carpets will last longer and require less maintenance in these ideal conditions.

Positive points

Steam and lingering food smells won't be a problem when you have Twista Roof Ventilators coupled with ceiling exhaust fans.

Positive points

You will enjoy shower-time even more knowing that all that steam is not being trapped inside your roof! The natural suction power of Twista Roof Ventilators is strong enough to pull water vapour outside where it belongs!

Negative points

Without any fresh air-flow in the roof, moisture builds up, then comes mould, wood-rot and even termites! These are dangerous and costly problems caused by an easily preventable problem!

Negative points

Try to looking at your windows in the morning. Do you see large amounts of condensation on them? This is not good! Imagine how much of this moisture is ending up up inside the walls, carpet and furniture!

Negative points

No matter how many times you try to clean it off, mould will come back, until you have addressed the root cause. The root cause is always excess moisture and insufficent air movement.

Negative points

Mould is not only unsightly it can literally be deadly. The spores from mould are terrible for your respiratory system and some toxic moulds are lethal. Don't risk your families health and wend well-being.

Negative points

In the cold winter months it is even more important to get water vapour out of your house. Are you noticing a lot of steam gathering when you have a shower? this is a due to poor ventilation.
