How do I replace marble window sills with wood ones?
September 14th, 2009 | by admin |Current windows are double paned (side sliders) and installed less than 5 years ago. The problem doesn’t seem to be the window, but the marble, which cold air radiates from. There is blown insulation in the walls, and I’ve checked to verify that there are no gaps between window/wall/marble sill. The house was built around the 1950’s. Would wood help? Should we keep the marble?
Wood doesn’t offer more than a negligible difference in any R value, albeit, may SEEM warmer to the touch. The "Radiant" coming from the sills cannot show in more than a negligible difference in costs to heat or AC, and the process to change them out, will not only be disruptrive to the structure, but labor intensive as well.

The wood may or may not help. You probably should pop off the trim and make sure they insulated around the windows when they installed them. Obviously, any gaps would cause air to get in. If you do find the windows need insulation, DON’T use the expanding foam. It will expand too much and can cause the window to warp. Use some loose fiberglass and lightly pack the cracks.
If you do want to replace the sill with wood, it’s not really that big of a chore. Just pop off the marble sill and replace it with wood. The marble is usually held on with some caulk. You can put new wood in with nails and/or construction adhesive.

Keep the marble. It’s a classy feature and would cost a fortune to do today,
