Efficient natural ventilation

Product description

INV100 Nature is the ultimate choice for ventilation of natural and fibre cement slate. The unique design makes it practically invisible. A grill protects the ventilation area against insects and driving snow. The original roof material is installed around the grill and fixed with adhesive butyl tape – leaving the grill is the only thing visible. A built in water stop leads rain water safely back on to the roof surface keeping the attic dry. The vent comes with an Ø110 mm adapter for connection to flex pipe. This can be shortened to increase the ventilation area to 10,000 mm².
