Each unit should be positioned so as to ventilate an equal portion of the roof.
Maximum ventilation roof vents.
In the meantime we are seriously considering the maximum ventilation model 301 and air intake vent vmax at1 df.
Our products were specifically designed to function in our northern climate where snow infiltrating an attic is a common occurrence.
The ventilation maximum however is more of a gloried button vent on steroids.
Ventilation openings having a least dimension larger than 1 4 inch 6 4 mm shall be provided with corrosion resistant wire cloth screening hardware cloth perforated vinyl or similar material with openings having a least dimension of 1 16 inch 1 6 mm minimum and 1 4 inch 6 4 mm maximum.

Ventilation openings shall have a least dimension of 1 16 inch 1 6 mm minimum and 1 4 inch 6 4 mm maximum.
The roof ventilators should be no further than 20 ft.
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.
Its unique storm proof deflector system prevents infiltrations while at the same time capturing the wind flow from any direction and at velocities as low as 4 miles hr.
It s passive like the standard buttons but because it rises from the roof and has more vent channels it can suck air out.
Our trained team of experts is on hand to answer any questions concerning our products and their installation.
It comes on an easy to install flexible mesh roll and is hand nailable with no complicated fitting wrapping nail gun adapters.
They could be adapted to all types and shapes of roofs as much for residential and commercial as for industrial and institutional use.

Apart from one another.
Model vmax at1 1213 df slope roof air intake vents the vmax at1 1213 df is a unique air intake vent designed and engineered specifically for buildings required to follow fire code regulations preventing the use of fresh air intake at the underside of the eaves or built in firewalls within the attic due to risk of fire propagation especially on row homes being so close to one another.
As a result one single model 301 can cover up to 1200sqft of attic space so you only need one ventilation maximum vs having 4 button types.
Unlike the turbine the 301 static ventilators does not require to rotate to prevent water or snow infiltrations.
Very efficient roof ventilator used to ventilate roof areas of 1000 to 1200 sq.
