Poly Design (tm)Shutters are made of superior cellular synthetic material. They are not made of cheap MDF (particle board), composite materials or hollow vinyls. Because the material is made of a solid construction, it will not delaminate or swell and end caps are not needed.
Poly Design (tm) goes the extra mile to ensure the shutters are engineered to last a lifetime. They can be cut, sanded, and painted just like wood shutters. The paint will never crack or peel and the finish will remain steadfast throughout the lifetime of the shutters. The materials are designed to be painted, unlike other synthetics
