How to repair a delaminated caravan window

A delaminated caravan window is never a good thing. Once that double glazing starts to pull apart, it can cause all sorts of issues. Thankfully, repairing a delaminated caravan window is easier than you may think.

In most cases, using a spot of glue on the delaminated area should be enough to keep the window going for a short while longer. However, sooner or later, you will probably want to replace that window.

On this page, we are going to tell you exactly why you should ensure that window delamination is dealt with quickly, as well as give you some quick advice on how you can repair window delamination while on the road. 

Why You Need To Repair a Delaminated Caravan Window 

When you have a delaminated caravan window, it means that the two pieces of double glazing on the window will have started to separate. This happens a lot more easily than it would on the double glazing on your home. In fact, most caravan users will eventually need to deal with a delaminated caravan window.

There are a couple of problems with having a delaminated caravan window. The first is the fact that rain is going to start creeping into the window. This can make the problem a whole lot worse. Not to mention the fact that your caravan is going to end up being a little bit worse in terms of insulation. This means that you are going to be ‘enjoying’ higher fuel costs.

The real problem with a delaminated caravan window, however, stems from the fact that wind can blow into it. This isn’t a huge problem when you are parked. However, when you are driving nice and fast, this can cause a window to blow out. Trust us. Having no window is going to be a whole lot worse than a delaminated caravan window!

How To Repair a Delaminated Caravan Window

Assuming that you want to repair the delaminated caravan window yourself, then you don’t need much. You just need some glue. Although, we have a couple of warnings for you here.

Firstly, you should only ever be using glue designed for acrylic (this is what your caravan windows have been constructed from). If you use any other type of glue, then it could ruin the windows. Thankfully, acrylic glue can be found in most hardware stores and supermarkets. You won’t have too many issues there.

Secondly, if your window has cracked, then you will not be able to repair the delamination. The only way that you are going to fix the problem here is to have the window completely replaced.

Finally, do bear in mind that this method may cause some scratches to your window. Again, there isn’t a whole lot that you are going to be able to do about that. It is due to the glue. Using glue is more of a stop-gap measure rather than a permanent solution.

With this in mind, all you need to do is spread the glue onto the delaminated area and push it flat. It will take a few hours to dry, so make sure that you are not driving for that amount of time. In an ideal world, you will want to try and do this on a dry day too. You don’t want there to be water creeping inside during the drying process.

If there is water inside of the delaminated window, then make sure that you dry it off first.

You Will Need The Window Replaced Eventually

Some people have claimed that gluing the two parts of the window back together has held for an exceedingly long time. However, if your windows are suffering from severe delamination, then we suggest that you get the problem dealt with quickly. Use the glue to help you to get back home, but we suggest that you make a beeline for a caravan repair company as soon as you can. They will either be able to permanently fix that window or, if it can’t be fixed, they will replace the window for you.

It, honestly, isn’t that expensive to get that window replaced. 


Delaminated windows can be a huge issue. Not only will a delaminated window provide less insulation for your caravan, but it can blow out while on the road. Thankfully, a bit of glue on the window will keep it in place until you can get a more permanent solution put into place by your local caravan repair company.
