Natural ventilation ridge
Natural ventilation is still a very good way of letting in fresh air if the outlet can be steered well. For this purpose Tulderhof has developed the ideal ridge, consisting in custom-made elements of 1 – 1,2 metres long. Either 4 or 5 elements fit between the truss. The ridge is covered with a sheet, preventing rain coming into the house. The ridge has got a fully computerized steering by 2 valves. Plus-point of these valves is that they can be perfectly cleaned after each round.
