I have been wondering for years what those spinning machines are on the roof of houses. I found out eventually that they are roof ventilators & they remove the heat trapped in your home. After some research, I found the Twista ventilators were head & shoulders above the rest. The patented internal fan system & the bigger size, made them the choice for my beautiful home.

	I noticed my neighbours had roof ventilators & I asked why they had them & what did they do. After finding out how successfully they cooled their houses, I decided to buy them for my home. I found Twista roof ventilators were an excellent product & guaranteed for life. I also liked the way they colour co-ordinated & blended nicely into our roof. I find now that my home is much cooler & more comfortable to sleep in at night. Peg, Panania
