Campervan Dometic windows: How to Choose the Best for Your Conversion
When it comes to outfitting your campervan, campervan windows are more than just openings for light and views—they play a huge role in your comfort, energy efficiency, and overall travel experience. Whether you’re upgrading your windows or planning a new build, understanding the types of campervan windows available—especially from trusted brands like Dometic windows, Seitz, and Polyvision—will help you make the right choice.
Why Campervan Windows Matter for You
Your campervan windows affect:
- Visibility & ventilation — Fresh air and natural light keep your space inviting.
- Thermal comfort — Stay cozy in the cold and cool in the heat.
- Energy efficiency — Reduce heating or cooling needs, saving battery or fuel.
- Condensation control — Avoid moisture buildup that can damage your van’s interior.
The Two Main Types of Campervan Windows: Single-Glazed vs. Double-Glazed
Single-Glazed Campervan Windows
Single-glazed windows have one layer of tempered or laminated glass. They’re lightweight, simple, and budget-friendly—often found in older or basic campervans.
- Best For: Mild climates, summer trips, or if you’re on a tight budget.
- Trade-offs: Minimal insulation means more heat loss in cold weather and higher chance of condensation.
- Thermal performance: U-values around 5.0-6.0 W/m²K (in simple terms, this means heat escapes quickly).
- Weight: Lighter than double-glazed options, which can help keep your van under weight limits.
Example: A basic Seitz single-glazed window can cost as little as 150 and install in about 1-2 hours.
Double-Glazed Campervan Windows
Double-glazed windows—like those from Dometic windows’s S4 or S5 ranges or Polyvision’s double-pane models—feature two glass panes separated by an air or inert gas layer (argon or krypton). This creates a powerful thermal barrier.
- Best For: Cold climates, year-round use, or if you want better comfort and energy savings.
- Trade-offs: Heavier and more expensive upfront (600+ per window) with a longer installation time (2-4 hours).
- Thermal performance: U-values between 1.5-3.0 W/m²K, which means 2-3 times better insulation than single-glazed windows.
- Condensation: Much less prone to moisture build-up inside your van.

Practical Guidance: How to Decide for Your Campervan
-
Consider Your Travel Climate:
- If you mostly camp in warm weather or short trips, single-glazed windows could save you money and weight.
- For colder trips or full-time van life, double-glazed windows from Dometic or Polyvision will keep your van warmer and reduce heating costs.
-
Think About Your Budget & Weight Limits:
- Single-glazed windows are cheaper and lighter—great for budget builds or smaller vans.
- Double-glazed windows cost more but pay off by improving comfort and protecting your van interior.
-
Plan Your Installation:
- Single-glazed windows can often be installed DIY in a couple of hours.
- Double-glazed windows might need professional fitting due to their weight and sealing requirements.
-
Check Brand and Quality:
- Brands like Dometic are known for robust double-glazed campervan windows with integrated blinds and ventilation options.
- Seitz offers reliable single-glazed windows popular in entry-level conversions.
- Polyvision focuses on high-quality double-glazed options with excellent thermal performance.
Final Thoughts
Choosing the right campervan windows is about balancing comfort, budget, and practical needs. If you want to stay cozy during chilly nights and save on heating power, investing in double-glazed windows from brands like Dometic or Polyvision is worth it. But if you prefer a lightweight setup for fair-weather trips, single-glazed windows from Seitz might be just fine.
Remember, your campervan windows don’t just frame your view—they shape your entire van life experience.
