Polycarbonate windows in hardtop
Currently I have a hardtop for my MGB that has glass side and rear windows. I use the car in sprinting the rules do not restrict what I do to the hardtop. My plan is to replace the glass windows with ones that I will make from polycarbonate (perhaps lexan to some of you). The windows will be glued in useing a PU type sealant but I may use some screws as well. The question in my mind is what thickness to use. I have an offcut of 3mm polycarbonate that is big enough to do the 2 small side windows. So my main concern is the rear window. I want to keep the weight down but it needs to be stiff enough not to act like Rolf Harris's wobble board. So anyone know what thickness to go for?

My Parish Plastics hard top uses 1/8" Lexan for the wraparound rear window.

Re: Polycarbonate windows in hardtop
Thanks Jim.
From the pictures I have seen of the Parish hardtop the back window has alot more curve to it than mine. While my hardtop is not a works one the back window is very similar. |

Re: Polycarbonate windows in hardtop
I know many racers here in the states with a lexan rear window will put aluminum strips to keep them from coming out and make them rigid. Sometimes the strips are required.
