Campervan Dometic windows: Why Choose Fixed Windows for Your Conversion?

When you're building or upgrading your campervan, choosing the right campervan windows is crucial. Fixed windows—like those from trusted brands such as Dometic windows, Seitz, and Polyvision—offer a unique set of benefits that might be perfect for your needs. Let’s break down what fixed campervan windows are, when to use them, and how they compare to opening windows to help you make the best decision for your van.


What Are Fixed Campervan Windows?

Fixed windows are non-opening glazed units permanently fitted into your campervan’s side panels or doors. Unlike sliding or hinged windows, fixed windows don’t open, so they won’t provide ventilation. Instead, they offer a sealed, secure, and weather-tight window that brings in natural light and improves visibility without the fuss of mechanical parts.

Why consider fixed windows?

  • No moving parts = less chance of leaks or mechanical failure
  • Stronger security: no handles or latches that burglars can tamper with
  • Better insulation: continuous seals keep your van warmer in winter and cooler in summer
  • Lower cost and faster installation compared to opening windows
