Kleer Crown extends visual interest upward by bringing walls and ceilings together with beautiful detail. Kleer’s innovative PVC formula helps its products install just like wood without the worries of bowing, splitting and warping common with wood crown products. Outside, crown moulding can elevate the design of a porch ceiling, a portico or as a custom cap moulding for PVC square columns. Intended for exterior use, PVC can also be used in any damp or wet area, covered or uncovered. KLEER brand PVC mouldings offer long-lasting duability and low maintenance.
