Doors and Windows - Questions on Skylight Heat Loss

Hi,

I live in Michigan, and lose a lot of heat through my skylights. The walls are wrapped with insulation in the attic, but the snow still melts badly around the skylight. I assume heat is escaping through the glass or through the skylight frame.

Is it possible to apply some sort of glaze or something to the glass to insulate it more?

Also, how would I go about checking for air leaks in the skylight frame? Would I have to tear them all apart or something?

Thanks much!

Jeg.

Heat rises -- the first place the snow will melt is off of the skylite, at the top of it's shaft. And even double or triple paned skylites, they will have less "R" (or insulation) value than a 2X4 or 2X6 shaft wall with insulation in it.

If you have condensation around the skylite, then you probably have an air leak. Otherwise, things are doing just fine.

On the same subject;

I'm planning on have tube skylights installed in my one-story home. What should I expect in regard to heat loss with them?

Thank you for your help.

Heat loss in the tube skylites is very little.

Thank you for the information. That's what I was hoping to hear.
