The Techni-Flo® Engineered Roof Ventilation System is the leading steep-slope roof ventilation solution. This state-of-the-art roofing ventilation system is engineered to ensure maximum airflow performance by balancing the intake and exhaust of steep-slope roofing applications. Roof ventilation of steep-sloped buildings is essential to maintain roof system durability and thermal performance. The Techni-Flo® engineered ventilation system provides balanced airflow to maximize building performance and exhaust the threat of moisture. Proper ventilation will help preserve the life of your roof.
Atlas Roofing Corporation manufactures a full line of engineered roofing solutions that are an integral part of the Atlas complete roofing system. The Techni-Flo® Engineered Roof Ventilation System consists of 4 parts: Techni-Flo® EV, ACFoam® CrossVent®, Atlas Nail Base Fastener and Techni-Flo® RV.
The Techni-FloTechni-Flo® RV (ridge vent) exhaust ventilation is engineered to ensure a perfect fit and optimum performance for every roof condition. Featuring an easy to install snap on cover, this all-metal ridge vent can withstand heavy snow-loads and wind-driven rain. Techni-Flo® RV features slotted fastening holes for easy installation and proper fastener placement.
Atlas ACFoam® CrossVent® combines the performance of a cross-ventilating air space, nailable roof substrate and thermally efficient polyiso insulation. ACFoam® CrossVent® consists of ACFoam®-II or ACFoam®-III polyisocyanurate (polyiso) insulation board and a min. 7/16” APA/TECO rated OSB or min. 19/32” CDX plywood separated with and bonded to 5 individual 1.0”, 1.5” or 2.0” vent spacer strips.
ACFoam® CrossVent® is available with an FSC® Certified wood layer upon request.
Atlas Nail Base Fasteners are specially engineered for attaching Atlas ACFoam® CrossVent® and ACFoam® Nail Base Roof Insulation to an approved substrate. Featuring a large, pancake style head with a 6-lobe drive, Atlas Nail Base Fasteners drive quickly and smoothly, and secure panels without the need of a washer. Atlas Nail Base Fasteners are available in three styles for use in wood, corrugated steel and steel members without pre-drilling.
Techni-Flo® EV is engineered for individual jobs to provide a prescribed roof ventilation capacity. This allows air to flow through the ACFoam® CrossVent® panel to the eave, heat and moisture to evacuate, and temperatures of the roof covering to be moderated. This, combined with proper eave ventilation, leads to a longer life for the roof. It also features slotted fastening holes for proper thermal movement and correct fastener placement.
Techni-Flo® EV is not intended for attachment to open ended metal truss or metal bar joist applications.
