Premium roof ventilators and exhaust traps

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. Our products were specifically designed to function in our northern climate where snow infiltrating an attic is a common occurrence.

The VMAX wall storm proof soffit is a unique soffit that has been specifically designed and manufactured to allow fresh air intake for attic air circulation while preventing any weather infiltrations into the attic space. Designed for flat or sloped roof applications, the wall mounted storm-proof soffit is a solution for any building with no roof edges. Due to its wall installation, this product offers the possibility of having a uniform and linear air intake entry around the perimeter of the building, thus promoting optimal attic ventilation.
