SPECIAL OFFER Ventilation pack
Additional roof vent plus a louvre, coloured finish
This special offer ventilation pack includes an additional coloured finish roof vent with a free automatic opener to provide fully adjustable opening. Roof vents can only be installed in a "hit and miss" sequence with a fixed pane of glass to each side of each vent.
A 6 blade coloured finish louvre is also included to provide low level ventilation. Louvres improve the air circulation through the greenhouse which prevents mildew and grey mould. Automatic openers are available to enable the louvre to ventilate in your absence. The picture shows a manually operated green finish louvre.
