Ridge Ventilators

Sandtoft offers a range of ridge ventilators and terminals to provide practical solutions for roof space ventilation, soil pipe and mechanical extraction. Within the range, concealed ventilators are available to maximise the aesthetic features of the roof by being virtually unseen once installed.
 
Flexible pipe adaptors are available for connection for soil pipe and mechanical extraction. A range of gas vent ridge terminals are also available to suit Sandtoft ridge profiles.
