How to Repair a Delaminated Caravan/Motorhome Window

Over time, caravan and motorhome windows can suffer from wear and tear, and one of the most common issues is delamination. This occurs when the double-glazed layers of acrylic begin to separate, often leaving a misty or bubbled appearance between the panes. Not only does it look unsightly, but it can also affect insulation and visibility. Fortunately, with a bit of care and the right tools, you can repair a delaminated caravan/motorhome window yourself.

What Causes Window Delamination?

Delamination is usually caused by:

• Age and UV exposure breaking down the adhesive

• Temperature fluctuations causing expansion and contraction

• Moisture getting between the window panes

Signs of Delamination

• Foggy or milky appearance between the panes

• Visible air bubbles or moisture

• Rattling or looseness when touched

Tools and Materials You Might Need

• Screwdriver (to remove the window)

• Acrylic adhesive (specifically for caravan windows)

• Plastic Spring clamps or weights

• Soft cloth or sponge

• Mild cleaner

• Isopropyl alcohol (for final cleaning)

• Safety gloves

  
  

Step-by-Step Repair Guide

The panes of the window can be sharp when delaminated , wearing protective gloves will prevent injuries

1. Remove the Window

Carefully unscrew the inner frame to release the window. Make sure to support the window from the outside to prevent it falling. Place it on a soft, flat surface to avoid scratches.

2. Clean the Window Thoroughly

Use a soft cloth and mild cleaner to remove dirt and grime. For the inner surfaces (where the delamination is), you’ll need to carefully separate the panes if possible. Clean the inside faces with isopropyl alcohol to remove any residue and moisture.

3. Apply Acrylic Adhesive

Apply a thin, even layer of acrylic adhesive to the inside of one pane. Be sure to follow the product instructions exactly. Avoid over-applying, as excess can cause smearing or bubbles.

4. Rejoin the Panes

Carefully press the panes back together, starting from one edge and working your way across to avoid air bubbles. Use clamps or place weights evenly over the window to hold the panes together while the adhesive cures. Leave for the recommended drying time (often 24-48 hours).

5. Refit the Window

Once the adhesive is fully cured, refit the window into the caravan. Tighten the screws evenly, and check the seal around the edge to ensure it is watertight.

Prevention Tips

• Park in shaded areas when possible to reduce UV damage

• Use window covers or thermal blinds during extreme weather

• Inspect seals regularly and reseal if needed

When to Call a Professional

If the damage is extensive, or you are unable to safely separate and re-bond the panes, it might be more practical to consult a caravan window specialist or consider a replacement.

Final Thoughts

Repairing a delaminated caravan window is a manageable DIY task with the right preparation. Not only can it improve the appearance of your caravan, but it also restores insulation and function. Taking the time to fix it yourself can save you money and keep your caravan in top touring condition.
