Fabulous Fiberglass Window Boxes

Lightweight and enduring, fabulous Fiberglass Window Boxes are built to last. Pound for pound, these lightweight planter boxes are just as rugged as their concrete or stone counterparts but at a fraction of the weight or cost. As such, they make great railing planters, wall planters, and window box planters. Plus, because of flexibility of the fiberglass flower boxes, we can make shapes and sizes that would otherwise not be available in heavier materials. In addition, this flexibility also includes the ability to apply unique finishes that mimic wood, stucco, and sandstone, among others.

Fiberglass window boxes are remarkably durable too. For example, unlike wood or concrete, they won't warp, crack, chip, or rot, lasting season after season, year after year. And the colors; while specific styles may come in a standard color, our custom department can paint whatever shade matches your home's exterior decor. Further, since paint adheres to fiberglass boxes better than a wood substrate, repelling water, the paint does not chip or peel. Sizes, too, are customizable so if you need a larger or smaller planter box to fit your unique space, we can accommodate your request down to the quarter inch.

Most of our fiberglass window boxes come with drainage holes created to drain away excess water so roots don't become waterlogged and rot. Some styles come with drainage mats as well. If the design you select does not, just let us know and we can add it to keep your plants healthy and robust.

Lightweight, Durable Fiberglass Flower Boxes

Finally, many of our lightweight planter boxes include wall mounting brackets that enable you to mount them to any flat surface. And with additional hardware (sold separately,) any of our wall planters can be converted to railing planters, dressing up your balcony or deck out back or the fence at the front of your home. Without a doubt, increasing the curb appeal of any home or business has never been easier with fabulous fiberglass window boxes.
