This probably sounds like a small thing, but it's turned out to be very important for the comfort of any guests we might have. I love our two guest bedrooms, but the one with the double bed, which faces east, has proven to be very hot in the morning. There isn't a veranda on that side, nor does the roof extend out very far. If we had it to do over again, we'd extend the roof a lot. Anyway, all our shutters are hinged at the side. We've kept the shutter on the east side closed most of the time to keep the sun from beating in. The problem with that is it also keeps the breeze, which generally comes from the east, from blowing in.
When Alejandro and Carlos were here, cutting down the trees, I had them remove the shutter and change the hinges to the top. Now it's propped partially open, protecting the window from the sun and the rain, but allowing us to replace the screen and have the breeze blow in.
Since the weather can be so extreme here. This should definitely be a consideration for anyone wanting to have shuttered windows. I have to add that we love our screened windows and wouldn't trade them for the louvered windows.
