The temperature in the greenhouse rises rapidly during a sunny  day. Short wave energy passes through the glass, converts to long wave energy as it bounces off the items inside the greenhouse and continues to bounce round inside the greenhouse.

Keeping and providing heat inside a greenhouse is highly dependent upon geographic location, where the greenhouse is sited, whether or not you have a dwarf wall and when you need to heat it.

There are a number of actions you can take to retain heat in the greenhouse.

Few of us have the luxury of spending endless hours in the greenhouse. If you have to leave the greenhouse for days at a time, or have uncertain hours to spend with your plants, then we can assist you to select automation to keep things going in your absence.

The three main types of glazing for greenhouses are horticultural glass, toughened glass or polycarbonate/perspex.

  • Horticultural Glass. 3mm thick, comes in 610x610mm squares. It is brittle and shards when broken producing sharp, knife like, edges. usually overlaid when used, causing unsightly and disease retaining algae and dirt to build up at the point of overlay. It cannot withstand movement of the greenhouse frame and will crack if the frame is moved off the square. It has been the standard greenhouse glass for many years, but is rapidly being replaced by toughened glass.
