Product Description & Reviews

Automatically opens and closes the roof vent/window when temperature changes. The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the vent. As the temperature cools, the mineral shrinks and a spring closes the vent and resets the piston. The opening and closing of the vent is gradual allowing just the right amount of air flow for cooling.

Features & Highlights

  • Opens roof vent automatically as temperature warms for air circulation and heat relief, Closes when temperature cools
  • Starting opening point: 75° F to 80° F
  • Solar powered, heat activated
  • No electricity needed
