Greenhouse Roof Height

We recommend choosing a practical height usually a maximum of 9 11 for residential solar greenhouses and then using the adjusted rule of thumb to ensure that the glazing meets the minimum pitch for light transmission.

Greenhouse roof height.

You can also change the height of the south facing wall to alter the angle. Greenhouses built during the energy crisis of the 1970s usually had an 8 foot height to conserve on energy. Today for various reasons 12 feet is the minimum and 16 feet is the standard with some houses being built with gutters more than 20 feet for some purposes. Builders continue to raise their roofs with every build.

Ventilation in a wide span greenhouse with a standard 6 12 greenhouse roof pitch the taller your sidewall height the better ventilation you ll get. However a tall greenhouse allows warm air to rise away from plant foliage so that temperatures remain relatively balanced at the floor level. A greenhouse height of approximately 13 feet is. Taller greenhouses allow you to produce more crop in the same footprint.

In fact the optimal height for a greenhouse appears to be 13 feet which allows for better airflow and temperature regulation with most plants getting exposed to mild but consistent temperatures around the bottom of the greenhouse.
