Simonton Prism Platinum Windows Reviews

The Simonton Prism Platinum window is the premium model in the Simonton Prism Series, and nearly identical to the Simonton Reflections 5500 window, although most Simonton distributors will carry one or the other, both not both. The window is a classic and clean vinyl window with clean sightlines for a streamlined appearance.

The Simonton Prism Platinum series comes standard with a 7/8 inch insulating glass unit, an interlocking meeting rail, a stepped sill, integrated lift sash rail, and a tilt in sash for easy cleaning. The window uses a fusion-welded construction and comes with the ProSolar Low-e glass, argon gas fills, intercept spacer and fiberglass mesh screen.

Consumers can choose from a number of different custom exterior frame colors such as bronze, brick, cream, chocolate, driftwood, pine, and tan. In addition, the Prism Platinum comes in a number of upgraded hardware options, including brushed nickel, dark or oil-rubbed bronze and polished brass.

The Prism Platinum model is one of the best offerings from Simonton, although perhaps not quite as nice as the Simonton 9800 Series.
