Formerly known as Dyer Environmental Controls Ltd. Natural and smoke ventilation brings buildings to life in positive ways for people and the planet. Our life-saving, life-enhancing systems make buildings supremely safe and comfortable as well as exceptionally energy efficient and economical to run. We’ve been creating passive ventilation solutions for over 20 years. You’ll find our systems in new builds and refurbishments including private houses, high-tech offices and fine heritage landmarks. People who love design know buildings are far more than bricks and mortar. They know an intelligently designed building lives, breathes and responds to circumstances– just like the people inside it.
