Cracked windows

I recently read some posts about broken windows and was curious why this happens.

Having given the van a spring clean before it's first outing I noticed that the windows were very difficult to open and struggled on the front (largest of course) window using the handles to try and push the window open.

A BIG MISTAKE!!!!

I eventually realised that the rubber seal around the window had attached itself to the van and ran a finger around the inside breaking the seal and freeing up the window.

Working on the van yesterday I noticed splits in the window around a handle so decided to dismantle to see the extent of the damage.

Frankly I am utterly appalled at the poor design of the handle/widow lock. In the vertical/unlocked position one would expect the handle to be able to accept the force required to open the window but it's not the case. If you exert ANY force on the handle and 15Kg would not be unusual, this force amplified because of the design of the handle by approx 3.5 times equals 52.5Kg onto the top edge of the bracket where it is attached to the window inner pane. The fixing screws acting as a fulcrum.

If you think of the old fashioned beer can stabber which you hooked under the rim and levered up. It's a similar action that you are putting onto a sheet of acrylic which has probably age hardened anyway. Age hardening generally makes things brittle.

So the moral of the story is NEVER NEVER use the handles to push open the window. ALWAYS ALWAYS run a finger around to break the seal if you feel any resistance and from now on I will be pushing with both hands spread as far open as possible on the window itself.

Does anyone know of a cheap window supplier?

Hello

I realise it's too late now but a smear of vaseline on window rubbers can help prevent the seal sticking to the plastic window. Hope you manage a satisfactory conclusion
