Insulated Glass Unit (IGU) vs Triple Glazing Low-E

Side-by-side comparison of the declared technical data for Insulated Glass Unit (IGU) and Triple Glazing Low-E. Rows are aligned by metric: the properties both sheets share come first, then the rest. Values come from Architheca material sheets; where a material has no datum you’ll see “—”.
