Cathedral Roof Vent VMAX

Special order: Custom made to the slope of the roof.
An insulated duct installed on the ridge of the roof to assure an efficent ventilation between the joists of the roof.

Ventilation Maximum designed and engineered a ventilation system in combination with the VMAX-301-12 ventilator that will allow, due to the ventilators exceptional drawing power, to draw fresh air from the soffits up between each rafter (between the insulation and underside of the roof deck) into an assembled weather tight duct system. It will then be extracted out the ventilator, thus, allowing for continuous fresh air flow throughout the attic space and preventing heat and moisture buildup from deteriorating the structural integrity of the building & its components.

Another valuable feature to this system is that it has been designed and developed to withstand the harshest weather conditions that Mother Nature could offer including hail & snow accumulations, thus, finally, giving the home owner peace of mind.
