When you say 'retractable' fly screens, do you mean the roller type ?

Did you use these for windows or doorways ?

Would be interested to see a price for them to compare to the company I used here in Bkk. We used the the roller screens throughout the house, I shall try to find a pic and post below.

Smaller window screens, retract into roller at top, so open and close vertically...but they can also be installed horizontally.
