GREENHOUSES

Greenhouse projects                                

       Greenhouses meet all modern cultivation requirements. Single or double glass, mounted with rubber strips, provides optimal daylight transmission. An alternative of fibre glass is also possible. The construction requires minimal maintenance. Optimal climate control is achieved automatically by an efficient system of ventilation, space heaters and evaporative cooling methods. Large exhaust fans and cooling corridors form the basis of the ventilation system. Various types and capacities of space heaters are suitable for partial and total house heating. A central switch panel  co-ordinates ventilation and heating, ensuring an even temperature throughout the greenhouse.

The cooling system utilizes the effect of evaporating water, by means of a cooling pat installed at the air intake of the greenhouse. The cooling effect increases as temperatures rise.

Some greenhouses have self-supporting rafters with various standardized sizes. With this construction, projects of any size with the most advantageous lay-outs can be built.
