Automatic Roof Vent Opener & Bug Screen

$0.00

The Bayliss automatic roof vent opener, made in England, is an elegant and efficient solution for maintaining the perfect climate in your greenhouse. This ingenious device harnesses the power of thermal expansion, utilizing a special wax compound that responds to temperature changes. As the temperature rises, the wax expands, gently lifting the vent to allow excess heat to escape. When the temperature cools, the wax contracts, gradually closing the vent to retain warmth.
