One of the most overlooked components of design and installation of roofing systems, both in new construction and retrofit applications, is ventilation. A properly engineered ventilation system using a proper ridge vent in conjunction with an under soffit intake will provide proper fresh air movement through the roofing system removing hot, stale air.
PreVent ventilators manufactured by Metallic Products are in accordance with the highest design requirements and specifications and feature eave and ridge/hip components for an efficient, maintenance-free roof ventilation system. These ridge vents are a low-profile, aesthetically pleasing and extremely efficient means of ventilating metal roofs.
In addition to being low cost and easy to install, PreVents have no moving parts to wear out. They are energy efficient, architecturally attractive and adaptive to many different roofing systems. They provide leak- and snow-proof ventilation and even protect against wind-driven rain infiltration.
