The X-Stream has a unique patented air flow. The X-Stream side air inlet opens in 2 stages creating a rolling air effect. This side air inlet also has a high insulation rating with the thick flap and EPS insulation. An overview of all the drawings for the opening dimensions of the different types of X-Stream side air inlets is given below. To be sure of the correct sizes, we recommend ordering embedded frames from Tulderhof.

Side air inlet with patented airflow

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.
