Pella's Designer Series of triple-paned windows provides more fire protection than double-paned while also offering a higher level of insulation and Energy Star qualification. The same radiant principle that makes a double-pane window better than a single-pane applies here: The sacrificial outer layers of glass allow the inner layer to heat up more evenly and resist cracking during a fire. The triple-pane windows also come with snap-in, snap–out window shades that are embedded behind the first interior layer of glass. Prices start at $900 for wood-frame models. Pella Corporation,
