Question
We are replacing a roof on a property of which there are four units. We own one of the units. We also have decided to replace the skylights.

Question: What are the best manufacturers of skylights to hold up in cold weather at 9,000 ft plus in elevation?

Tks

Answer
Hi Judy:
Wow; 9000 ft.! I'm trying to guess where that could be; maybe a Park Service building in Yellowstone somewhere?
At any rate; one primary consideration at that elevation will be degredation of glazing from UV light.  Many manufacturers of the various 'plastics' used in skylights make various claims regarding this characteristic; if you want to keep costs down and use one of these plastic types, you should check the ability to resist UV carefully.
Otherwise, I would stick with good old fashioned thermal glass (safety glass of course) and one of the major manufacturer's:  Pella, Anderson, etc., which will stand behind their warranties.
Best of luck with your project!
