casement windows

Jalousie windows were designed for a life without air conditioning. In Panama, where you cool 24 hours a day, they leak air at five to seven times the rate of any modern replacement window — and your AC fights every cubic foot of it. We walk through the U-factor, SHGC, air leakage ratings, and frame types that matter in a hot-humid climate, what thermally broken aluminum means and why it is non-negotiable here, and what window film can and cannot do for renters who cannot replace what they have.
