A truck off the road is a truck not earning, which is why this work is done where the vehicle is rather than at a workshop.
Truck windscreens differ from car windscreens in more than size. Many are held in a heavy rubber locating seal rather than bonded to the body, and a good number of trucks use a two piece split screen where each half is replaced separately. Cab height also means the job is worked at a different level to a car.
We replace glass on light and medium commercial trucks and on machinery cabs, and we work around the access and safety requirements of the site we are attending.
