Ventilation Maximum

In the early 1980’s, Ventilation Maximum designed and developed a new line of static ventilators for attics. They could be adapted to all types and shapes of roofs, as much for residential and commercial as for industrial and institutional use. Products were specifically designed to function in our northern climate where snow infiltrating an attic is a common occurrence.
