At JMK Shutters, We Can Offer You Custom Poly Shutters

Polycore custom plantation shutters are elegant and high quality. Polycore shutters leverage a breakthrough technology of polymer construction with a metal core for enhanced strength and durability. Polycore shutters give an attractive painted wood-like appearance, plus the louvers are wider than traditional shutters and have an elliptical profile that adds to the quality and subtle elegance of the product. For many homeowners and commercial properties, polycore shutters offer a price saving over custom wood plantation shutters.


Polycore custom plantation shutters offer the best of both worlds – you get high quality and durability, plus the graceful and elegant look of wood plantation shutters.
