Protects turbine roof vents from rain, snow, wind and dust while cutting indoor heat loss and extending vent life. Key benefits Weather protection: Waterproof Oxford cloth shields turbine vents from rain, snow and airborne dust to prevent water ingress and internal wear. Energy savings: Covers reduce heat loss through roof vents during cold months, helping improve home energy efficiency. Secure in strong winds: Reinforced ferrule and tether system plus an elastic base keep the hood in place on turbine vents with external support structures. Easy to use: Installs and removes quickly without tools—elastic rope at the base makes attachment fast for seasonal changes or temporary use. Built to last: Oxford fabric resists erosion, UV exposure and wear so the cover maintains protection under continuous outdoor use. Clear compatibility: Designed specifically for turbine vents with external support structures in two sizes: 30 x 45 cm (12' x 17.5') for 12' turbines and 51 x 51 cm (20' x 20') for 20' turbines. Available in black or beige. How it works Place the hood over the turbine vent, align the reinforced ferrule and tether to external supports, and secure the elastic rope at the base. The combination of tether points and elastic prevents displacement in gusty conditions without needing tools or permanent fixtures. Typical applications Winter protection: Install before the first snow to reduce drafts and keep melting snow and ice from entering the ventilation shaft. Stormprone or coastal homes: Use where strong winds and airborne salt or sand can accelerate corrosion or clog vents. Seasonal storage or maintenance: Quickly cover vents during roof work, longterm building vacancy or while transporting a mobile structure to prevent debris intrusion.
