Benefits of solid surface window sills

Our solid surface sills are made to order from either high quality CORIAN® or HI-MACS® products. These solid surface sills look as good as granite, marble, or other stone, but are much cheaper and easier to cut and install.

In addition, CORIAN® or HI-MACS® sills have tremendous advantages over wood or vinyl sills.

  • permanent color. No fading or discoloring from UV rays
  • no warping or cracking with temperature changes or moisture
  • durable and long lasting
  • easy to install
  • no painting needed
  • low maintenance requirements
  • coordinate well with other materials such as wood, metal, glass, or tile

Whether you’re looking for an attractive, low-maintenance and durable sill in a shower, bathroom, or kitchen, or for good-looking, contemporary sills to go with your interior décor, we can provide a sill to suit.
