At Superior Door and Glass Services Insulated or thromopane glasses are no problem for us and we provide at least a 10 year limited warranty on our IG units which can be upgraded to 20 years.

Insulated Glass Units with grids (or muntin bars) in between the panes.

To measure for pricing we only need a rough size on the window panes, whether they have grids or not, and what the window frame is made of (wood, metal, vinyl, etc.) to give a quote.  To prevent fogging both panes of glass or the insulated unit itself must be replaced with a new warrantied unit.  Unfortunately there is no way to reseal just one piece of glass in the window.
