We can provide a variety of roof hatches, made to order with a selection of actuation, control and material options.
To provide a means of access to roof areas and prevent unauthorised access from above
In any natural ventilation scheme involving conventional industrial buildings the optimum position, under normal circumstances, is to provide a system of air extraction through the highest point of a building. The Kenstack can be mounted high up the roof slope just below the ridgeline.
It can be manufactured to suit any pitch of roof and can be fixed to any type of sheeted or decked roof.
The Ventilators are offered in a range of materials and colours to colour match or contrast with the roof claddings.
Each Ventilator is custom made to suit individual requirements with a variety of functional and control options.
