A few images of a BMW windscreen being fitted correctly to an F11 (2012 5 Series Touring). There are many misconceptions about windscreens and how they are installed. The aim of this post is to show the key stages so that you can gain a better understanding of how your windscreen is fitted.
First, the substrate is cleaned and removed of any contaminants as part of the pre-bonding preparation:
Preparation is crucial; get this wrong and it’s only a matter of time before the problems begin to manifest themselves. Here you see the addition of Polyurethane adhesive (PUR) and a thick strip of absorbent material across the bottom of the glass.
The new (OEM) windscreen comes with all the correct hardware:
Special attention to detail includes ensuring the windscreen will be ‘set’ at the recommended height by using the correct buffers, and positioning them according to the manufacturer’s specification:
The windscreen is now set in place and aligned against markers set-out from laying the screen in ‘dry’. This reduces any time spent on measuring to centralise the glass.
No scratches to the paintwork means no black paint to hide them (one of the biggest misconceptions on what ‘black’ adhesion promoter is used for).
Before the A-pillar trims are refitted, a few checks are made just to satisfy that there is good contact of PUR between the two surfaces.
Camera, rain/light sensor, condensation sensor and the rear view mirror assembly are reintroduced:
