We have a nice municipal swimming pool here in the Colorado Rockies, completely enclosed with a metal framework, and what I would call clerestory windows mounted vertically way up high in the framework. They have had problems with condensation on the windows that results in water dripping down on the metal framework, resulting in corrosion.
They originally had double pane windows, but had cracking problems and replaced them with single pane windows. I have not yet tracked down details on the windows, but assume they are mounted in a metal frame. Temperature differences across the windows are quite high, with temperatures as low as -5 F outside and 110 F inside.
Heat is supplied by natural hot springs, and reducing heat loss is not the issue. Rather, reducing condensation is the issue. Single pane windows seem a poor approach to me, due to the very low temperatures of the inner surface of the glass.
They are currently redoing the ventilation system to try to reduce the humidity that collects up high near the windows.
Anybody have thoughts on window designs or manufacturers that might be especially suitable for the high differential temperatures of up to 115 F and very high humidity that would not have cracking issues? |
