Nordwood upgrade

Automatic window opener

Ventilation that runs itself. A heat-sensitive wax cylinder opens your Nordwood roof window as the garden room warms up and closes it again as it cools. No electricity, no batteries, nothing to remember.

  • Opens gradually as the temperature rises, closes as it falls
  • Fits every Nordwood roof window (Greenhouse, Classic, Arrow, Arrow with Shed)
  • No power or wiring, works on a wax cylinder
  • One opener per roof window: 4 on the Nordwood Greenhouse and Classic, 2 on the Arrow, 1 on the 8' Arrow

Description

A glass garden room warms up fast on a sunny morning. The automatic opener takes care of that for you: as the air inside heats, the wax in the cylinder expands and pushes the roof window open; as it cools, the window settles closed again. Plants get steady ventilation all day and you never come home to a cooked greenhouse.

It mounts to the roof window frame with the supplied bracket and can be fitted in a few minutes with a screwdriver. Fit one per roof window for even airflow.
