Manthorpe In-Line Slate Vent (GILSV25-20)

Manthorpe In-Line Slate Vent (GILSV25-20)

The small format in-line slate ventilator is a low profile, unobtrusive solution to ventilation requirements through a roof covered with slates up to 500x250mm in size. The integral pipe outlet is perfect for extraction and requires no additional adaptor. The vents flat profile with it’s lightly textured finish helps to maintain an unbroken appearance to the roofline whether used at high or low level. The tortured path through the 4mm louvred grill and internal weathering geometry is designed to maintain airflow whilst channelling any water ingress out of the vent and on to the roof covering. The vent can be used with 500 x 250mm sizes slates down to 400 x 200mm coverings and various sizes in between
