Tulderhof - X-Stream Wall Inlet

The X-Stream was born of an innovative redevelopment of the classic side air inlet by Tulderhof. The flap opens in 2 stages: first at the top to send air to the ridge. Then the flap also opens at the bottom, partially deflecting the air downward. This creates a gentle rolling effect. This specific airflow is patented by Tulderhof. This side air inlet is made of durable plastic, the inlet is thicker than normal, and it contains high-quality EPS insulation. Both factors guarantee a high insulation value.
