⁉️ Frequently asked questions
Q: What is the difference between the Dometic S4 and our Vanlife sliding windows (SLIDE / SQUARE SLIDE)? A: The S4 is the Dometic reference — historic motorhome brand — with very clear glazing (90% brightness) to maximize light. Our Vanlife sliding windows (SLIDE, SQUARE SLIDE) offer a dark tint (10 to 30% light transmission) for more privacy, and accept thicker walls (up to 75 mm without wooden frame).
Q: My vehicle has a wall thicker than 41 mm, can I still install it? A: Yes, but you will need to make a wooden frame to bring the mounting depth to a thickness within the 26-41 mm range. If you prefer to avoid this step, consider our Vanlife sliding windows which accept up to 75 mm as standard.
Q: Is it certified? A: Yes, E32 / 43R marking — certified for use in Europe.
Q: When to choose a sliding window rather than a projecting one? A: By default, we recommend the projecting window (opening up to 70°, usable in rain, better sealing). Choose a sliding window where a projecting one would be inconvenient: behind a roof ladder, on a rear panel near a sliding door, or anywhere the window must not protrude from the bodywork.
