With the help of my wife all the windows were fitted today.
She very patiently stuck the sealing strip on
I fitted them into the shell. 138 screws in all and all done the old way. I now have a sore hand.
These are the windows I used I am very pleased with them. Fitting was easy and I hope when they need to come out for repainting they will come out just as easy. Just need some rain now to test for water tightness, although ATM that seems unlikely so the hose might come out.
