Vitavia Automatic Roof Vent Opener

This Vitavia Automatic Roof Vent Opener helps control greenhouse temperature. It contains a special wax inside. When the greenhouse gets warm, this wax expands. This expansion pushes the roof vent open automatically. It lets excess heat escape easily.

As the temperature drops, the wax inside cools down. It begins to shrink and solidify again. This action pulls the roof vent closed. This keeps the remaining warmth inside your greenhouse. Please note, this opener is designed for Vitavia greenhouses only.

Vitavia Green Top Tier Staging Extension
We bought the top staging to increase capacity in our greenhouse. These have really proved useful already. I am delighted with the staging and would thoroughly recommend them and the good service of the company who supplied them.
