The figures for Kappafloat are for viewing the glass from the coated side, i.e. when the Kappafloat is the inside pane. If the Kappafloat is used as the outside pane then values should be obtained from another source.

The Saflex and Saflex Shadowlite glasses are laminated glass with a 0.38mm interlayer
