Roof Vent VMAX-201-MB - Ventilation area 151 to 450 ft2
Deflectors: 4
Base: insulated interior
Height: 24 1/2 in.
Ventilation area: 151 to 450 ft.2
Unlike the gooseneck, the Maximum Ventilators are CSA approved. Its unique storm proof system prevents infiltrations while at the same time capturing the wind flow from all directions and at wind velocities as low as 6 km./hr. (4 mi./hr.). With this combination of technology, wind and pressure differentials, a “chimney or, vacuum effect” results in drawing the stale air and moisture out, thus preventing moisture & heat build-up within the attic space.
All in one, no need of a wood curb, this model has been designed to allow you to install the roofing membrane onto the base flashing the same way you would a wood curb. We have made an allowance for the membrane so that the neck of the ventilator will go over both the flashing and the membrane.
