About Sill-Rite

Started in 2005 in Ontario, California, Sill-Rite produces vinyl interior window sills for the building industry. Karl Hatrak, President and founder, invented the Sill‑Rite sill as a waterproof product to replace drywall and MDF sills. “Drywall was never intended to be used as a finished sill,” says Karl. “MDF is even worse at protecting the sill area and underlying wall from moisture resulting from window condensation and leaks.”

Sill-Rite products are available through various dealers and select Home Depot locations. Products can also be purchased on-line.
