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.
