   The thermal protection wil still be OK, but if the seal is shot and moisture is inside, you will need a new one.

   Bright side, though, is that the new ones are MUCH better than the older ones.

   Quality repairs for your home.

   I'm surprized they can't reseal them.

   No doubt it is possible to reseal them ... but no one does it because it is cheaper to replace them.  I think quite a bit cheaper.

   AH!!, The subject of my first post here a few years back!!

   The "fogging" is actually etched into the galss, NOBODY has ever been able to tell me what the precise mechanism is, and I've not invested the effort/cost to run a microprobe/chromatograph analysis.  Best related knowledge to date is biological, a specific enzyme that reacts with glass and needs moisture.  If it were soley chemical, D. T. would have known.

   I have slit apart the panes with heat gun and custom bent knife and tried to clean, and the surface is literally pebbled,  which is how I found they were etched. Tempered glass has less of an etching problem so may be ameniable to cleaning. Reseal with silicone on a dry day or blow with N2 out of your welding tank while resealing if you are a good DIY.

   If I can get around the $$$ motivated political codes for IG here, the next house I build for myself will have old fashioned storm windows __ with modern type door seals.

   you'd think the glass co.   would at least give you some kind of trade in credit for two pieces of perfectly good tempered glass.

   Check out the warrantee, a lot of them are 10-20 years and a few are lifetime.
