Window Box Liners

Window Box Liners - Copper, PVC, Aluminum In PVC, we offer both architectural grade liners as well as light duty window box inserts. Our Flower Window Boxes TM brand architectural grade PVC window box liners are made of a thick material that looks and feels like wood. Unlike other liners, the high grade plastic material will not warp, sag, crack, distort, or fade over time. They're also paintable and will hold any exterior latex for up to 15 years. These architectural window box liners can be custom made in all three dimensions: length, width, and height. We also offer a wide range of standard sizes as well.

PVC window box liners and planter box liners offer a quality upgrade over traditional liners and can be used as inserts for existing wooden window boxes or wrought iron window boxes to help prolong their longevity and enhance their look. Flower box inserts and liners in general are not necessary with any of our window boxes because they can be planted directly into. However, we do offer our exclusive line of light duty window box inserts below for those who like the convenience of using removable inserts for hard to reach windows.

Window Box Inserts and Liners ComparisonFor those looking to hang one of our architectural liners from the wall, we recommend getting our Modern window boxes instead. They are made from thicker materials and have a stronger frame, and are backed with our lifetime warranty.
  • PEAK SEASON: All Liners SHIPS FULLY ASSEMBLED in approximately 4 weeks (not a kit). These are built to order by professional carpenters.

Aluminum and Real Copper Liners
In addition to our PVC liners we also offer metal liners made from aluminum with a copper coated finish (copper tone, dark brown, and silver) as well as liners made from real copper. The real copper liners come in two finishes (untarnished and patina finish). Untarnished copper liners will naturally patina green over time. We also offer a PVC liner with a specialized paint finish using real copper paint and an acid wash for those who want to get the same look of patina copper but at a fraction of the cost.
