What are the pros and cons of casement windows versus sliding windows in new home construction?

I'm building a home in Boquete, Panama. Temperatures are 70 to 80 degrees year round.

My plans call for casement windows. The builder has asked whether I want casement windows or whether I want to switch to their standard, sliding windows. As I understand it, both are aluminum.

My inspector tells me casement windows are better: for preventing break-ins and for low maintenance. He says the sliding windows have vinyl rollers that wear out in a year or two and have to be replaced.

One of my concerns is that the house has stone planters under many of the windows, some within six inches or a foot of the bottom of the window.

Which type of window is better for my situation and why?

Thanks for your help.

pros for casements

1) better air infiltration ratings since sash closes against frame
2) more view (no annoying bar in check rail where sashes meet.
3) easier to escape from in case of fire (more room)
4) easier to operate in most cases
5) more air flow when open

cons for casements

1) casements open to the outside which means that they have to have room to open outwards

I personally don't know any good reasons to buy sliders. rollers do wear out eventually.

also i would highly recommend vinyl over solid aluminum. aluminum windows conduct heat and cold and are very low energy efficient material.

if you have any other questions email me.
