Dometic Seitz S4 Hinged Window 900 × 400 mm

Proven motorhome and caravan window with blackout blind & insect screen

The Dometic Seitz S4 hinged window 900 × 400 mm is a proven side window for motorhomes and caravans. The double acrylic glazing and robust polyurethane frame provide good thermal and noise insulation, making the S4 a durable solution for recreational vehicles and caravans.

The lightly grey-tinted acrylic pane opens outwards using side-mounted telescopic stays. Thanks to the integrated friction hinges, the pane can be continuously adjusted up to an opening angle of approx. 75° and held in almost any desired position. This allows comfortable and flexible ventilation of the vehicle interior.

Integrated blackout blind and insect screen

The Dometic S4 window features an integrated blackout blind and insect screen. Both can be operated independently or connected to each other.

The blackout blind provides privacy and sun protection, while the insect screen allows fresh air to enter through the open window while helping to keep insects outside. The S4 therefore combines ventilation, blackout and insect protection in one coordinated window system.

Robust frame construction for motorhomes and caravans

The sturdy polyurethane outer frame is finished in Black (RAL 9005), while the inner frame is Cream White (RAL 9001). An integrated safety locking system helps prevent the closed window from being opened from the outside.

The Dometic Seitz S4 hinged window is suitable for wall thicknesses from 26 to 41 mm. The specific installation and overall dimensions of this version can be found in the short description and under “Technical Details”.
