Window Board

When working on new builds or renovating old windows, you’re going to need strong, reliable materials for the window sills. At HSS, you’ll find a wide selection of window boards now available to buy online.

Our high-quality window boards cover the gap between a window and a wall, as well as supporting the weight of the window. Not only are they easy to install but the window boards are also durable, airtight and are made from moisture resistant MDF.

You can use the boards for windows in your living rooms, kitchens, bedrooms & other rooms around your home. As the boards have a smooth finish, once installed you’ll be able to paint, stain, or varnish your new window sills to suit your own personal preference.
