Timberland Shutters: Beautiful poly shutters with a wood stain finish Timberland Shutters are an innovative product from Sunburst Shutters & Window Fashions. Timberland is a poly shutter with all the benefits of a non-wood product: no possibility of cracking, splitting, fading, etc. But unlike poly shutters, Timberland comes in wood stain finishes. You can choose from a Chestnut stain color or a Dark Walnut—both look amazing and can fit a variety of decorating styles. Both stain finishes look like real wood but last like poly. It’s the best of both worlds.
