- Product Summary
- The VMAX-AT1-1224-L/S models are rectangular air intake louvers designed for water-shedding roof systems. These products have been designed specifically for buildings where fire code regulations are applied to prevent fire propagation to the attic via soffit air intakes, or when the presence of firewalls in an attic hinder the amount of air intake required for attic ventilation. It is also used in situations where soffits are non-existent or non-functional. Installed directly on the bottom of the roof above the eave and/or even with the fascia, these air intake louvers allow the supply of fresh air to circulate continuously in the attic to prevent the accumulation of heat and humidity.
